高速碰撞共沉淀法铜基甲醇合成催化剂的研制

THE PREPARATION OF Cu BASED CATALYSTS FOR METHANOL SYNTHESIS BY HIGH SPEED COLLISION COPRECIPITATION METHOD

开发出高速碰撞共沉淀制备铜基甲醇催化剂的新方法。用此法一步共沉淀制得的ｂ 催化剂，其分散度和催化剂表面单位Ｃｕ 原子的ＣＯ 转化数比ｅ 催化剂分别增加２０％ 和１４ ％ 。在催化剂Ｃｕ 质量分数减少３７％ 的情况下，其催化剂活性仍相当高，因此这是一种值得推广应用的催化剂制备新方法。

New method of high speed collision coprecipitation for preparing catalysts have been developed.Prepared catalysts by means of the method can increase the dispersion and CO conversion of unit Cu atom on catalyst surface by 20% and 14%,respectively.Catalytic activity still was efficient when Cu component was decreased by 37%,therefore this is worth applied new method for preparing catalysts.
