Description
Technical field
Warm hydrolytic catalyst of carbonyl sulfur and preparation method thereof belonged to catalyst and preparation field thereof with purposes during the present invention was a kind of, relate in particular to a kind of in warm hydrolytic catalyst of carbonyl sulfur and preparation method thereof, be mainly used in and remove organic sulfur in the unstripped gas.
Background technology
As everyone knows, organic sulfur particularly cos (COS) extensively to be present in coal, natural gas and oil etc. be in the Chemical Manufacture unstripped gas of raw material, its existence can cause catalyst poisoning inactivation in the subsequent production process.Particularly present, be used for preparation and new technology or The Study on New Technology, exploitation and the uses such as coal gas Poly-generation and the conversion of water at low temperature steam of synthetic raw gas along with colm and oven gas, in the meticulous technology of cos that removes in the gas of temperature paid much attention to, and meticulous to remove in the cos technology effective method be middle temperature cos catalyzing hydrolysis.At present both at home and abroad the patented technology of relevant cos catalyzing hydrolysis is many, is broadly divided into three classes according to its serviceability temperature: normal low temperature (room temperature～150 ℃) carbonyl sulfide hydrolysis catalysis patented technology, middle low temperature (80～250 ℃) carbonyl sulfide hydrolysis catalysis patented technology and middle temperature (200～400 ℃) carbonyl sulfide hydrolysis catalysis patented technology.Normal low temperature (room temperature～150 ℃) the carbonyl sulfide hydrolysis catalysis technique patent application time early and many, as the CN1704145A of the CN1095309A of the CN1102420C of the CN1189394A of the CN1069673A of Hubei Prov. Chemical Research Inst and CN1844326A, Institutes Of Technology Of Taiyuan and CN1680025A, Shanxi Inst. of Coal Chemistry, Chinese Academy of Sciences, SINOPEC Qilu Petro-Chemical Corp and CN1056096C, Changchun Dongshi Technology and Trading Industrial Co., Ltd. etc.Catalyst all is to select γ-Al for use basically in these patented technologies
2O
3Carrier or γ-Al
2O
3-TiO
2Complex carrier, what the load active component alkali metal compound was prepared on the carrier of selecting for use then, what the use of catalyst was primarily aimed at all is normal low temperature fine desulfurizing technology.Though catalyst serviceability temperature difference in the different patented technologies, serviceability temperature is in room temperature to 150 ℃ scope basically, and catalyst mainly is to be used for low concentration cos catalyzing hydrolysis.
Middle low temperature carbonyl sulfide hydrolysis catalysis patented technology is as CN1134312A, the CN1403197A of East China University of Science, CN1323735A, the CN1593751A of Tongji University of Hubei chemistry institute, the CN1564710A of Axens, the CN1602998A of Weifang Lianxin Chemical Co., Ltd. etc. of Catalyst Plant, Nanjing Chemical Industry (Group) Corp..Catalyst mainly also adopts γ-Al in these patented technologies
2O
3-TiO
2Composite oxides or rare-earth oxide are carrier, add cobalt then, the molybdenum oxide makes, and is mainly used in the catalyzing hydrolysis of cos in the Sulfur Recovery Unit process, and serviceability temperature is mainly in 80～250 ℃ of scopes.
At present warm carbonyl sulfide hydrolysis technology abroad pay much attention to, CN1675337A as Mitsubishi Heavy Industry Ltd., for cos in the gas that reduces the gasification generation, serviceability temperature is at 200～400 ℃, external Fr2236555, UK1307875, US4500668, WO9943195 etc. in addition, in these patents, catalyst mainly is used in the Sulfur Recovery Unit process, serviceability temperature is all more than 100 ℃, and great majority are more than 200 ℃.
The use of normal low temperature carbonyl sulfide hydrolysis catalysis technique has following characteristics: the suitable hydrolysis of low concentration cos gas, equilibrium conversion height, can avoid sulfation to poison, be used widely in the gas fine desulfurizing technology.
In warm cos catalyzing hydrolysis technology compare with normal low temperature hydrolysis technology and have following characteristics: 1. technological process coupling, advanced person's the low temperature coal gas steam conversion process operating temperature that for example has high conversion efficiency removes warm cos catalyzing hydrolysis technology during cos need adopt in the gas after the conversion so between 200～400 ℃; Synthol ether catalyst serviceability temperature during the Poly-generation that gasification gas and pyrolysis coal gas are made synthetic raw gas is altogether used also requires at middle temperature catalyzing hydrolysis to best at carbonyl sulfide removal in the unstripped gas before synthetic between 250～350 ℃ so.2. can be flux matched, the technical process that we mention from the front as can be seen, if adopt normal low temperature cos catalyzing hydrolysis technology, the gas temperature that at first needs to contain cos reduces by indirect heat exchange, reaches the needed temperature of normal low temperature cos catalyzing hydrolysis technology, and the gas after the desulfurization improves temperature to reach follow-up synthetic requirement through indirect heat exchange more then, there be twice energy exchange in the carbonyl sulfide hydrolysis sulfur removal technology thus, energy utilizes unreasonable, complicated operation, and equipment is huge.
But when present carbonyl sulfide hydrolysis catalysis technique is used in middle temperature, there is the poisoning problem.We think that the hydrolytic catalyst of carbonyl sulfur mechanism of poisoning mainly contains to experimental study with analyzing the back: 1. the sulphur deposition is the main cause of catalyst poisoning under the low temperature (200 ℃); It is the main cause of catalyst poisoning that high temperature (200 ℃) is gone up sulfation; 2. has only H
2S and O
2Make the time spent catalyst simultaneously and just produce poisoning; 3. temperature has tangible influence to catalyst poisoning, and temperature high catalyst is more poisoned obvious more; 4. oxygen concentration also has appreciable impact to catalyst, and oxygen concentration improves catalyst deactivation rate and increases.Thus, the anti-poisoning performance of warm carbonyl sulfide hydrolysis technology is the innovation part of middle temperature cos Preparation of Catalyst and technique for applying in the raising.For example two patents of invention of the CN1844326A of the CN1675337A of Mitsubishi Heavy Ind. Ltd. and Hubei Inst. of Chemistry are exactly to eliminate oxygen the gas from technology, make the cos catalyst in the gas of anaerobic, carry out the cos catalyzing hydrolysis, finally improve the anti-poisoning capability of carbonyl sulfide hydrolysis technology.Comprise O among the CN1675337A
2Remove catalyst and COS reforming catalyst, described COS reforming catalyst is with respect to described O
2The removal catalyst is placed in the downstream of gasification air-flow.Utilize O
2Remove O in the catalyst burning gases
2, prevent O
2Cause the activity of COS reforming catalyst to reduce.But, be used for O in this method
2The precious metal catalyst that burning removes costs an arm and a leg, and is easy to H
2S poisons, and causes performance to descend, and the heat that produces on the combustion catalyst produces immense pressure to peripheral unit on the other hand.The modified activated carbon of packing among the CN1844326 is to eliminate O in the gas
2Influence to follow-up COS hydrolyst poisoning.As from the foregoing, use on the technology innovation to eliminate in the gas oxygen, have complex process, the equipment requirement is high and remove O the cos catalyst poisoning
2Catalyst or deoxidier cost an arm and a leg and the anti-O of COS catalyst
2The weak deficiency that waits of poisoning capability.Therefore innovate from the cos Preparation of Catalyst, carry out the modification of catalyst performance, invent a kind of can be significant at middle temperature decline low-sulfur fouled catalyst.
