Homogenous catalytic hydrolysis of high-concentration COS in CO atmosphere

LI Xiuping,LI Chunhu,YANG lin,WANG Linxue (Key Laboratory of Marine Chemistry Theory and Technologyof Ministry of Education,Ocean University of China,Qingdao 266003,Shandong,China)  
Homogenous catalytic hydrolysis reaction of COS in CO atmosphere was studied in a bubble column reaction system.The influence of catalyst concentration,gas-to-liquid ratio and temperature on the COS hydrolysis activity and stability of the catalyst system were investigated.The results showed that,the higher the temperature and gas-to-liquid ratio,the lower the COS conversion;COS conversion increases with concentration of the catalyst.The optimum reaction condition was as follows: 10% aqueous solution of the catalyst,gas-to-liquid ratio 150 h-1,ambient pressure and room temperature.
