Product Description

1. Features and Scope of Application Some catalysts used in hydrocarbon-based large-scale ammonia plants is sensitive to sulfur compounds and prone to be poisoned and deterioration in activity when sulfur content in feed gas exceeds certain value. Cobalt –molybdenum hydroconversion catalyst and zinc oxide are usually used for desulfurization of feed gases or oils. T**1 hydroconversion catalyst, with high organic sulfur conversion capability, is applicable to hydroconversion of feed gases for large-scale ammonia plants. It can bring down organic sulfur in feed gases to less than 0.1 ppm. Main hydroconversion reactions involved are as follows: RSH+H2 = RH+H2S R1SSR2*3H2 = R1H+R2H+H2S R1SR2*2H2 = R1H+R2H+H2S C4H4S*4H2 = C4H*0+H2S COS+H2 = CO+H2S where R=alkyl groups. This product is also applicable to organic sulfur hydroconversion of light oils or gaseous hydrocarbons in petrochemistry
