Abstract
An organic sulfur hydrolysis catalyst and a preparation method thereof. The catalyst consists of 4-20 wt% of titanium dioxide and gamma-alumina. The preparation method is that refined aluminum hydroxide and titanium hydroxide are mixed according to a proportion and then are rolled into balls for molding. Treating the semi-finished ball with a special washing solution, activating and calcining. The catalyst has good hydrolysis effect on carbonyl sulfide, carbon disulfide, mercaptan, thioether and the like, and can further convert hydrogen sulfide generated by hydrolysis into elemental sulfur for recycling. At airspeed of 1800 DEG C-1The content of COS reaches 5000 mg/m3Under the condition, the hydrolysis conversion rate is more than or equal to 90 percent, and the organic sulfur hydrolysis catalyst can be widely used for hydrolyzing organic sulfur in desulfurization devices in various industries.
Description
The invention belongs to the catalyst class, relate to organic sulfur hydrolyst and preparation method thereof.
The nineties, China introduces advanced foreign technology, builds up tens covers in succession and adopts the coke oven gas purification that ammonia decomposes and the Sulfur Recovery Unit technology combines to reclaim new technology.Wherein in the claus reaction device except that filling sulfur recovery catalyst, also must load the part organic sulfur hydrolyst, (mainly be cos, content is at 3000～5000 milligrams/meter to be used for organic sulfur with acid gas
3) be hydrolyzed into hydrogen sulfide, and further be converted into elementary sulfur.China's first cover adopts CR type sulfur recovery catalyst, the CRS-21 type organic sulfur hydrolyst of the device imported France Rhone-Poulenc production once of this new technology.From relevant documents and materials, CR type catalyst is full alumina balls, and CRS-21 type catalyst is to make with CR type catalyst soakage titanium compound.Domestic also have similar catalyst, for example LS-811 type, a LS-821 type catalyst.The same with CRS-21 type catalyst, LS-821 type catalyst is to make with LS-811 type catalyst soakage titanium compound.Restricted by manufacturing condition, CRS-21 type catalyst and LS-821 type catalyst have a common characteristic, and promptly active component titanium dioxide mainly is distributed in catalyst coating, and titanium dioxide easily runs off in the use, cause catalytic performance to descend.
Domestic have in the TG series that a class organic sulfur hydrolyst such as the Ministry of Chemical Industry's chemical fertilizer researched and developed in addition, the low temperature organic sulfur hydrolyst, and inlet cos content is at 100～200 milligrams/meter
3Organic sulfur hydrolyst (Chinese patent CN1069673A) disposal ability of Hubei Prov. Chemical Research Inst research and development is littler, only 1～5 milligram/meter of inlet cos content
3This class catalyst all is to adopt alkali metal such as alumina balls dipping sodium, potassium, is used for that Fischer-Tropsch is synthetic, the smart desulfurization of ammonia factory and other unstripped gas.
The purpose of this invention is to provide a kind of hydrolyst and the unique preparation process thereof that can handle the high level organic sulfur.This activity of such catalysts uniform component distribution is difficult for running off, and longer service life is of a specified duration.
Technical scheme of the present invention is that titanium hydroxide and the aluminium hydroxide that will refine mix, roller forming, handles with the weak acid solution cyclic washing that contains ammonia, and catalyst of the present invention is made in activated, calcining.Catalyst main active component content of titanium dioxide is 4～20% (weight), and crystalline form is a Detitanium-ore-type, and carrier is a gama-alumina.
At first refining titanium oxide.Titanium-containing compound is handled with mixing ammonium salt solution, put into centrifugal separator and dry, repeatable operation is up to qualified.The wet cake that makes is put into oven for drying, is crushed to≤0.045 millimeter (330 order), obtains the titanium hydroxide of content of titanium dioxide 〉=80% (weight).
The synthetic method of aluminium hydroxide is a lot, can be according to the working condition method production of choosing any one kind of them, granularity should≤0.045 millimeter (330 order), and the dehydration back stirs in mixer by a certain percentage with titanium hydroxide, keep 70～150 ℃ of mixed material temperature, roller forming.The weight ratio of aluminium hydroxide and titanium hydroxide is 7～15.
Preparation contains the weak acid solution (PH4～7) of ammonia in the sink that can lead to the even heating of steam, the semi-finished product ball is put into groove wash.Logical an amount of steam is kept the wash solution temperature at 70～100 ℃ in the washing process; Join the wash solution washing again after changing clear water washing, qualified up to impurity contents such as pore structure and sodium, iron.Wash solution is with preparations such as deionized water and ammonium salt, acetic acid, prepares variable concentrations according to the impure situation of semi-finished product ball, and PH is 4～7.
200～300 ℃ of activation 2～3 hours in activation furnace of titanium aluminium ball oven dry back by said process preparation place calcining kiln to calcine then, 500～600 ℃ of calcining heats, and calcination time 3～5 hours makes catalyst of the present invention.
Catalyst of the present invention is the spheric granules of 3～8 millimeters of diameters, is made up of the anatase titanium dioxide and the gama-alumina of 4～20% (weight), and impurity contents such as sodium, iron, magnesium, calcium, silicon all are lower than 0.1% (weight).This catalyst has higher specific surface area (180～300 meters/gram) and pore volume (0.4～0.6 milliliter/gram), crush strength 〉=130 newton/.
Embodiment:
The aluminium hydroxide that takes by weighing 2 kilograms of granularities and be 0.045 millimeter carries out processed, and other takes by weighing 180 gram granularities is 0.045 millimeter refining titanium hydroxide, stirs roller forming, about 80 ℃ of mixed material temperature in mixer.Wet bulb is put into polybag and was left standstill 16 hours.
Take by weighing ammonium chloride 80 gram and be dissolved in 8 liters of deionized waters, add acetic acid and transfer to PH in right amount and 5 be made into wash solution; The semi-finished product ball is put into cleaning solution, logical Steam Heating, the cleaning solution temperature maintenance is at 80～90 ℃; Change the clear water washing after one hour.It is qualified up to middle control detection to repeat aforesaid operations.
The titanium aluminium ball that washing is good is dried back 300 ℃ of activation 2 hours, and 580 ℃ of roastings got final product in 4 hours.
Catalyst of the present invention contrasts with CRS-21 type catalyst result of use under identical industrial operation condition of French Rhone-Poulenc: certain coke-oven plant uses CRS-21 type catalyst, when stopping, for the first time annual overhaul gets a little detection of active, conversion ratio less than 50%, accumulative total is used and is changed catalyst of the present invention after 2 years, used more than 2 years up till now, effect is fine always, does not find to exceed standard phenomenon.
The activity of such catalysts test is carried out in the glass reactor of 28 millimeters of internal diameters.The employing original catalyst particle size detects, 20 milliliters of loadings, and 220 ℃ of reaction temperatures are during air speed 1800
-1, normal pressure, activity is represented with the COS hydrolysis conversion.When in the unstripped gas during COS content 0.2% (volume), catalyst of the present invention is suitable with CRS-21 type catalyst activity, all 〉=90%.
Catalyst of the present invention has that reactivity is good, working strength is high and is steady The qualitative good characteristics that are difficult for inactivation. The specific area of catalyst of the present invention Greatly, pore structure is good, has hydrolysis and sulfur recovery dual-use function.
Catalyst of the present invention also can be used for sour crude oil and natural gas processing, Organic sulfur removal in various synthesis gas or the town gas preparation process.
