从甲醛催化剂的改进,展望甲醛工业发展前景

A View of Development Prospect of Formaldehyde Industry Throuth the Change of Formaldehyde Catalysts

甲醛生产所用催化剂经历了铂催化剂、铜催化剂、浮石银、银网、电解银、铁钼氧化物催化剂的变迁,从不断提高设备生产能力,降低物料消耗,减少环境污染起了积极的推动作用。通过对催化剂性能和制作工艺的比较,简述了我国甲醛工业工艺技术的进展和新技术的前景。

The catalysts used in formaldehyde production changed platinum catalyststo copper catalysts, pumice silvers, silver nets, iron- molybdenum oxides and electrolysis silver etc. , which made active pushing forward in continuously enhancing output capacity of the equipment, reducing the consumption of the raw materials and minimizing the pollutions the environment. A brief description of the technology progress and the new technology prospect of formaldehyde industry in the country with comparison of catalysts activity and their product processes made in this paper.
