 Type JT203 hydroconversional dearseinder catalyst is a new developed product by our factory. It is made of Nio-MoO3-AL2O3 with the specific promoter. The producing process used the most advanced together immersion technology in our country. The product has more hydroconversional ability for organic sulphide. Oxygen and organic nitrde, especialy for all kinds of orgainc arsenider and inorganic arsenider, the product has excellent ability for hydroconversional and dehydrogenization. Type JT201 catalyst can be used in all large sizes ammonia syntehticmanufactory. Smelt factory for purifying and refining raw material.

The main reaction of Hydroconversion as follows:
|
R3As+3H2→3RH+AsH3
AsH3+M→MAs+3/2H2
RSH+H2→RH+H2S
R1SSR2+3H2→R1H+R2H+2H2S
C4H4S+4H2→C4H10+H2S
CnH2n+H2→CnH2n+2
COS+H2→CO+H2S (R=alkyl, M=active metal)
