石油化工厂产生的废铋钼硅催化剂为淡黄色粉末。经有关部门分析,其中含铋(Bi)和钼(Mo)分别为46%和12%(均以氧化物计)。我们对其进行了小型的再生试验并扩大到投料一公斤的试验。研究的目的在于用简单的化学方法比较经济地回收其中的稀
Waste bismuth molybdenum-silicon catalyst produced in the petrochemical plant is light yellow powder. According to the analysis of the relevant departments, the contents of Bi and Mo are respectively 46% and 12% (all based on oxides). We conducted a small regeneration test and expanded it to a one kilogram feed. The purpose of the study was to recover the leanness more economically using simple chemical methods
