Abstract
The present invention is a kind of sweetening agent that removes multiple organosulfur composition from gas, contains by at least a at least two kinds in Manganse Dioxide, ferric oxide and the zinc oxide hosts of forming, cupric oxide and the rare-earth oxides to form for assistant agent and conventional weighting agent.This sweetening agent also has the function that removes micro amount of oxygen in the gas simultaneously except that desulfidation.
Description
What the present invention relates to is the sweetening agent of organic sulfide removal from gas.
Along with the development of modernization oil chemical industry technology, a lot of high activated catalysts are very strict to the content requirement of sulphur in the unstripped gas (Sweet natural gas, synthetic gas, lightweight gas-liquid attitude hydro carbons etc.).The method of organic sulfide removal composition generally has oxidation style from these unstripped gases, and hydroconversion process and hydrolysis conversion method are several, and commonly used is back two kinds at present.The subject matter that these sweetening agents exist, one is to use the mode limitation big, and versatility is poor, and the 2nd, desulphurizing activated temperature is higher.For example: a kind of iron-manganese-zinc sweetening agent has continued among the Chinese patent CN85103555A, though similar sweetening agent with other is than the advantage with organic sulfide removal species wide ranges, but desulfurization method is mainly hydrogenolysis and pyrolysis transforms, adopt the gas of this kind mode desulfurization then can't use to being not suitable for, and its desulphurizing activated temperature is also higher, greater than 350 ℃.Other hydrolysis at present transform the class transforming agent except that have equally that the mode of action is single can not be general, also must remove converted product hydrogen sulfide thereafter with other sweetening agent.
The present invention's purpose at first provides and a kind ofly organosulfur composition in the gas is transformed in many ways and absorbs, and has the sweetening agent of good low temperature active.
A further object of the present invention provides a kind of sweetening agent that can also remove the micro amount of oxygen in the gas when having above-mentioned same desulfurization performance.
The effective constituent of sweetening agent of the present invention comprises host and assistant agent two portions, host is Manganse Dioxide, at least two kinds of compositions in three kinds of compounds of ferric oxide and zinc oxide, assistant agent is at least a in cupric oxide and the rare-earth oxide, wherein rare-earth oxide can be the oxide compound of various rare earth elements such as neodymium, lanthanum, thorium, cerium, and be with the form of mixtures of multiple rare-earth oxide for well, needn't separation and purification.In this sweetening agent, host content should be 30-90%(weight), assistant agent is a 0.5-20%(weight), rest part in addition is conventional weighting agent, as compositions such as carriers such as aluminum oxide, silicon oxide, graphite, clay, cement, lubricant, binding agents.For sweetening agent of the present invention can also being had from containing carbon monoxide or/and remove the function of micro amount of oxygen the gas of hydrogen when extensively removing multiple organosulfur composition, suggestion should contain Manganse Dioxide at least or/and contain cupric oxide in the assistant agent at least interior in the host of above-mentioned effective constituent.
An outstanding feature of the above-mentioned sweetening agent of the present invention is exactly to make Special Circumstances and the needs of same sweetening agent according to gas with various, can take cracking respectively, different modes such as hydrogenation or hydrolysis transforms multiple organosulfur composition such as thiophene, mercaptan, thioether, carbonylsulfide, disulphide and absorbs and be removed, and have good low temperature active and penetrate Sulfur capacity, the selectivity height, long service life.For example: take off light oil with hydrogenolysis and pyrolysis way essence, (total sulfur can reach 500-1000mgs/Nm when Sweet natural gas, organosulfur in coke(oven)gas and the hydrogen
3) active temperature reaches more than 300 ℃ and get final product, and can reduce about 50 ℃ than present similar sweetening agent; With hydrolysis method remove be rich in carbon monoxide gas (as coal gas, water-gas, synthetic gas, during organosulfur composition conversion gas etc.), can have good conversion assimilating activity from 100 ℃, also hang down about 50 ℃ than similar sweetening agent, and selectivity is good, carbon monoxide disproportionation and methanation side reaction are atomic.At least include in the composition Manganse Dioxide and/or cupric oxide at interior sweetening agent in desulfurization under the active temperature, can also remove the micro amount of oxygen in the gas satisfactorily.For example: when 100-200 ℃ lesser temps, the micro amount of oxygen in the coal gas is removed by optionally changing into carbonic acid gas with carbon monoxide; Make oxygen and hydrogen be combined into water and be removed in that 150-250 ℃ temperature is next, the decreasing ratio of micro amount of oxygen all can solve the particular requirement that need remove the micro amount of oxygen composition as some gases such as methyl methanol syngas in desulfurization again well more than 80%.
That below introduce is some embodiment as content of the present invention.The composition of each example (weight %) sees the following form, and various components can be from industrial raw material or/and the oxide compound of natural component or carbonate.Behind each component mixing, promptly become operational sweetening agent after adopting dried mixed extruded moulding, the roller forming under the conventional industrial condition or beating the sheet shaping and roasting.
Claims (3)
1, a kind of sweetening agent of forming by metal oxide that removes organosulfur composition in the gas, it is characterized in that containing by at least two kinds in Manganse Dioxide, ferric oxide and the zinc oxide and be assistant agent two constituents at least a in host and cupric oxide, the rare-earth oxide, wherein host content (weight) is 30-90%, assistant agent is 0.5-20%, and all the other are conventional weighting agent.
2, sweetening agent as claimed in claim 1 is characterized in that should containing Manganse Dioxide in the said host.
