In the production method, semi-coke or coke powder is loaded with a catalyst and reacts with sulfur. The catalyst can be the carbonate of alkali metal or alkali-earth metal, metallic oxide, the sulfate of transition metal or metallic iodides. The method opens up new raw material for producing carbon disulfide, completely replaces charcoal raw material, and avoids results of destroying the environment because of charcoal use. Moreover, the used semi-coke or coke powder is solid residues in the coal gas production with raw coal or leftover coke powder in coke pulverization in a coke plant, and thus, the problem of environmental pollution is solved.
Description
Technical field
The present invention relates to a kind of preparation method of dithiocarbonic anhydride, being specially a kind of is the method that raw material is produced dithiocarbonic anhydride with carbon or carbonaceous material.
Background technology
It is to adopt charcoal and sulphur at high temperature to react to obtain the purpose product that traditional method is produced dithiocarbonic anhydride; but because this production method need consume a large amount of timber; along with the protection of country's increasing to forest; the charcoal raw material reduces day by day; price significantly improves; therefore, the substitute of searching charcoal becomes the task of top priority.
In the prior art, utilize methane very ripe abroad for the technology of raw material production dithiocarbonic anhydride, domestic existing imported technology is being used, but because of being subjected to the restriction of methane feed place of production limitation and transportation difficulty, in China minority area this technology of use of having ready conditions is only arranged.Be difficult to satisfy the demand that day by day increases at present both at home and abroad to dithiocarbonic anhydride.
People once tested and use coal or coke to be raw material production dithiocarbonic anhydride in the past, but because of the physical strength of coal is low, the composition complexity, the foreign matter content height, destructive distillation easily under the dithiocarbonic anhydride temperature of reaction produces coal tar and a large amount of gas, destroys the carrying out and the polluted product of main reaction.Use coke to be raw material, many unfavorable factors are also arranged, higher such as coke ash content, influence yield; Especially carbocyclic ring is dense in the coke, and the bond energy between the carbocyclic ring is difficult to break, and directly influences the reaction of carbon and sulphur, and it is that the yield of raw material production dithiocarbonic anhydride is very low that these two reasons make with coke, can not form industrial capacity.Once enumerated the experimental result that metallurgical coke, refinery coke and pitch coke are used for carbon disulphide production as English Patent GB705724 Improvements in or relating to preparation ofcarbon disulphide and active carbon.Show utilize above-mentioned three kinds of typical carbon or carbonaceous material produce dithiocarbonic anhydride industrial be uneconomic.
English Patent GB649448 disclosed " improved carbon disulphide production method " (Improvedmanufacture of carbon disulfide); Disclosed a kind of method of producing dithiocarbonic anhydride with coke powder; English Patent GB705724 disclosed " production technique of dithiocarbonic anhydride " (Improvements in orrelating to preparation of carbon disulphide and active carbon); What disclose is the technology of producing dithiocarbonic anhydride with a kind of acid sludge Jiao (acid sludge coke).Above-mentioned technology is not all applied industrial.
The inventor once tested the semicoke that uses the direct destructive distillation of raw coal to form and produced dithiocarbonic anhydride, particularly adopt weak cementability coal, test such as the semicoke that brown coal, bottle coal, rich coal or gas-fat coal obtain after without the direct destructive distillation of coal blending, yield can reach more than the 30-35%, though can be in industrial application, economic benefit is not high.Be difficult to replace existing charcoal raw material.
Summary of the invention
The present invention is directed in the present domestic carbon disulphide production traditional raw material source and face the carbon material based on coal out of stock, a large amount of and but have the lower problem of yield, proposed a kind of technical scheme of catalytic activation method production dithiocarbonic anhydride as alternative raw material.
Catalytic activation method of the present invention is produced the method for dithiocarbonic anhydride, react under 800-1000 ℃ of hot conditions by carbon or carbonaceous material and sulphur and to obtain dithiocarbonic anhydride, described carbon or carbonaceous material are semicoke or coke powder, and reaction is to carry out under the condition of semicoke or coke powder supported catalyst.
Described catalytic activation method is produced the method for dithiocarbonic anhydride, and wherein catalyzer is the vitriol or the metal iodide of basic metal or alkaline earth metal carbonate, metal oxide, transition metal.
Described catalytic activation method is produced the method for dithiocarbonic anhydride, semicoke or coke powder equi-volume impregnating supported catalyst wherein, and semicoke behind the supported catalyst or coke powder were dried 2-8 hour down at 100-120 ℃; The charge capacity of described catalyzer is 0.1-10%.
