Abstract
The invention relates to a hydrogenation catalyst carrier for coal liquefaction oil, a catalyst as well as a preparation method and application of the hydrogenation catalyst carrier and belongs to the field of hydrogenation catalysts. The carrier comprises the following components (counted by 100% of total weight of the carrier): 5-60wt% of carbon nanotube, 32-90wt% of aluminum oxide, 0-8wt% of silicon dioxide and 0-8wt% of titanium dioxide. When the hydrogenation catalyst carrier for the coal liquefaction oil is used for carrying out a hydrorefining reaction for directly liquefying low-grade oil by coal, after the reaction is continuously carried out for 48 hours, the desulfurization rate can reach 99.7%, the denitrification rate can reach 95.1%, and the deoxygenation rate can reach 99.5%; after the reaction is continuously carried out for 168 hours, the desulfurization rate can reach 98.9%, the denitrification rate can reach 94.6%, and the deoxygenation rate can reach 98.6%; the hydrogenation catalyst carrier has high catalytic activity and stability.
Description
Technical field
The present invention relates to a kind of liquefied coal coil catalyst carrier for hydrgenating, Catalysts and its preparation method and application, belong to catalyst field, particularly relate to a kind of hydrogenation catalyst for liquefied coal coil hydrofining technology, and prepare this catalyst carrier, with and preparation method separately.
Background technology
Along with the accelerated development of process of industrialization, worldwide oil shortage cannot be avoided.Coal resources in China is the most sufficient in three macrofossil energy resources, makes full use of the coal resources of China's abundant, and Devoting Major Efforts To Developing coal for replacing oil, coal liquefaction technology, be to reduce the effective way that oil lacks risk.At present, liquefied coal coil technology is to realize the main method of coal for replacing oil, coal liquefaction.Liquefied coal coil technology is under HTHP, and hydrogenation makes the organic matter in coal be converted into liquid fuel, and this liquid fuel is liquefied coal coil.Liquefied coal coil, by further hydrofinishing, can form the fuel oil such as gasoline, diesel oil.
