Abstract
The present invention provides a renewable fuel production system by biomass conversion by integrating a bio-oil production system with a conventional refinery, co-processing bio-oil with petroleum-derived streams in the refinery to produce renewable fuels in commercially desirable quantities; the technology used to integrate the bio-oil production system with the conventional refinery is selected according to the quality of the bio-oil and the product required by the refinery.
Description
Technical Field
The present invention relates to a system for producing renewable fuels by biomass conversion, and more particularly to a system for integrating a biomass conversion facility with a conventional oil refinery to efficiently produce renewable fuels.
Background
Renewable energy sources are becoming increasingly important as the costs associated with fossil fuels rise and environmental concerns. The development of renewable fuels provides a means to reduce the dependence on fossil fuels. Many different areas of research are therefore currently of particular importance in exploring and developing renewable fuels.
Biomass is increasingly being listed by researchers as an ideal feedstock for renewable fuel research due to its low cost and wide availability. Accordingly, related chemical research agencies have developed many different conversion processes that utilize biomass as a feedstock to produce useful biofuels or specialty chemicals. Existing biomass conversion processes include combustion, gasification, slow pyrolysis, fast pyrolysis, liquefaction, and enzymatic conversion. One of the useful products that may be produced during the above-described biomass conversion process is the liquid product bio-oil, commonly referred to as "bio-oil," which can be processed into transportation fuels, hydrocarbon chemicals, and specialty chemicals.
Despite the advances in research and research in biomass conversion processes, many of the existing biomass conversion processes produce low quality bio-oils that are extremely unstable and often contain large amounts of oxygen. These bio-oils require extensive secondary upgrading for use as transportation fuels or as fuel additives due to their instability. In addition, the quality of transportation fuels or fuel additives derived from bio-oil depends on factors that affect the stability of the bio-oil, such as the original oxygen content of the bio-oil. In order to process bio-oil into renewable fuels and/or fuel additives, various upgrading treatments can be performed on the bio-oil. However, current upgrading processes are relatively inefficient and the use of the produced renewable fuels or fuel additives in today's market is very limited.
Disclosure of Invention
The present invention relates to a method for producing a renewable fuel, wherein the method comprises the steps of: providing one or more bio-oils selected from the group consisting of high stability bio-oils, medium stability bio-oils, and low stability bio-oils, wherein the high stability bio-oil has a stability parameter of less than 30 centipoise/hour (cp/h), the medium stability bio-oil has a stability parameter between 30 and 75 cp/hour, and the low stability bio-oil has a stability parameter greater than 75 cp/hour; processing at least one bio-oil in a refinery according to one or more of the following: (1) combining at least a portion of the high stability bio-oil with a first petroleum-derived stream at a refinery to form a first combined stream, hydrotreating the first combined stream to produce a first hydrotreated stream, and fractionating the first hydrotreated stream; (2) combining at least a portion of the high stability bio-oil with a second petroleum-derived stream from the refinery to form a second combined stream, catalytically cracking the second combined stream to produce a second cracked stream, and fractionating the second cracked stream; (3) combining at least a portion of the intermediate stability bio-oil with a third petroleum-derived stream from the refinery to form a third combined stream, hydrotreating the third combined stream to thereby produce a third hydrotreated stream, catalytically cracking at least a portion of the third hydrotreated stream to thereby produce a third cracked stream, and fractionating the third cracked stream. (4) Combining at least a portion of the medium stability bio-oil with a fourth petroleum-derived stream from the refinery to form a fourth combined stream, hydrotreating the fourth combined stream to produce a fourth hydrotreated stream, thermally cracking at least a portion of the fourth hydrotreated stream to produce a fourth cracked stream, and fractionating the fourth cracked stream; (5) combining at least a portion of the low stability bio-oil with a fifth petroleum-derived stream from the refinery to form a fifth combined stream, thermally cracking at least a portion of the fifth combined stream to produce a fifth cracked stream, and fractionating the fifth cracked stream; (6) combining at least a portion of the low stability bio-oil with a sixth petroleum-derived stream of the refinery to form a sixth combined stream, fractionating at least a portion of the sixth combined stream into at least a sixth heavy bio-fraction and a sixth light bio-fraction, hydrotreating at least a portion of the sixth light bio-fraction to thereby produce a sixth hydrotreated bio-fraction, and thermally cracking at least a portion of the sixth heavy bio-fraction to thereby produce a sixth thermally cracked bio-fraction.
Drawings
FIG. 1 is a schematic diagram of an integrated biomass conversion and petroleum refining system according to one embodiment of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, fig. 1 illustrates a biomass conversion system 10 integrated with a refinery 12 via an integrated system 14. The manner in which the biomass conversion system 10 is integrated into the refinery 12 may vary depending on the bio-oil produced and various properties of the desired products of the refinery 12 (e.g., stability or oxygen content). As shown in fig. 1, integration of the biomass conversion system 10 and the refinery 12 may allow for commercial scale production of renewable fuels, such as bio-gasoline, bio-jet fuel, biodiesel, bio-fuel oil, or bio-coke. The biomass conversion system 10 includes a biomass source 16 for supplying a biomass feedstock to be converted into bio-oil. For example, the biomass source 16 may be a hopper, a storage silo, or any other device that can hold or store biomass. The biomass provided by biomass source 16 may be in the form of solid particles. The biomass particles can be a fibrous biomass material comprising cellulose.
As shown in fig. 1, solid biomass particles from biomass source 16 may be supplied to biomass feed system 18. Biomass supply system 18 may be any system capable of supplying solid particulate biomass to biomass conversion reactor 20. While in biomass feed system 18, the biomass material may undergo a number of pre-treatments to facilitate subsequent conversion reactions. Such pre-treatments may include drying, roasting, oven drying, demineralization, mechanical agitation, or any combination thereof. The biomass is combined with the catalyst in the biomass feed system 18 prior to introduction of the biomass into the biomass conversion reactor 20, or the catalyst may be introduced directly into the biomass conversion reactor 20. The catalyst may be fresh or regenerated. Biomass feed system 18 introduces a biomass feedstock into biomass conversion reactor 20. In the biomass conversion reactor 20, the biomass undergoes a conversion reaction to produce bio-oil. The biomass conversion reactor 20 may facilitate various chemical conversion reactions, such as fast pyrolysis, slow pyrolysis, liquefaction, gasification, or enzymatic conversion. The biomass conversion reactor 20 may be, for example, a fluidized bed reactor, a cyclone reactor, an ablative reactor, or a riser reactor.
When fast pyrolysis is performed in the biomass conversion reactor 20, the conversion products 21 typically comprise solid particles of coke, ash, or spent catalyst. The conversion product 21 may be introduced into a solids separator 22. The solids separator 22 may be any conventional device capable of separating solids from gases and vapors, such as a cyclone separator or a gas filter. Solids separator 22 removes a majority of the solids (e.g., spent catalyst, coke, or heat carrier solids) from conversion products 21. The solid particles 23 recovered in the solids separator 22 may be introduced into a regenerator 24 for regeneration, typically by combustion. After regeneration, at least a portion of the thermally regenerated solids may be introduced directly into biomass conversion reactor 20 via line 26. Alternatively, the thermally regenerated solids may be directed to biomass feed system 18 via line 28 for combination with the biomass feed prior to introduction into biomass conversion reactor 20.
