活性氢物质存在时丁硫醚在HZSM催化剂上的催化脱硫转化反应研究

摘要

The catalytic desulfurization of a model organic sulfurous compound n-butyl-sulfide in a fixed bed micro-reactor is studied in the presence of catalyst and a hydrogen provider. The experimental results show that the appropriate reaction conditions are: a mixed catalyst of HZSM-5 zeolite and Co-Mo/Al2O3-TiO2, a reaction temperature of 300℃, atmosphere pressure, a feed speed of 50 mL/h and a mass hourly space velocity of 3.0 h-1. A higher catalytic property and desulfurization efficiency of the mixed catalyst of HZSM-5 zeolite and Co-Mo/Al2O3-TiO2 is achieved. The adsorption and desulfurization efficiency of the FCC gasoline from Shenghua Refinery, which is affiliated to China University of Petroleum (East China), is 53.0%.
