一种铁钼法甲醛生产工艺及其催化剂

本发明涉及一种铁钼法甲醛生产工艺及其催化剂。所述方法采用列管反应器，反应器上端为铁钼催化剂、下端为金-铁钼催化剂，制备甲醛过程中，尾气中的CO被催化氧化为CO2，CO2循环回反应器入口稀释原料,并起到抑制甲醇深度氧化的作用，提高整体甲醛的收率。本发明同时还提供了所述金-铁钼催化剂的制备方法。 The invention relates to an iron-molybdenum method formaldehyde production process and a catalyst thereof. According to the method, a tubular reactor is...
