【Abstract】 In view of deficiency in technique for production of formaldehyde using silver as catalyst, Jiangyin Huayan Petrochemical Mechanical Equipment Co., Ltd. introduced advanced technique for producing formaldehyde into our country based on exhaust gas cycling using silver as catalyst. And its process flow sheet, process characteristics, and “three wastes” treatment were described in detail. Finally, a comparison between the two technologies catalytic by silver and iron molybdenum was made, merits of exhaust gas cycling technique for production of formaldehyde were shown significantly.更多还原
