硫磷硅毒物共存对甲醇催化剂失活的影响

STUDY OF DEACTIVATION EFFECT ON METHANOL CATALYST BY COEXISTENCE OF THE SULFUR, PHOSPHORUS AND SILICON CHEMICALS

摘要: 本文采用电子能谱仅、x光衍射仪、BET吸附仅、原子吸收光语仪等分析仪器，对硫、磷、硅共存时对甲醇催化剂中毒失活情况进行研究和剖析。结果表明：硫、磷、硅共存时甲醇催化剂的中毒与硫或硫氯存在时甲醇催化剂的中毒明显不同，毒物完全破坏了催化剂原有的表面结构。

Abstract: The investigation and anatomy have been made with Methanol catalyst using several physical-chemical instruments and chemical analytical methods. The results show that the use life of the catalyst is affected much badly while the sulfur, phosphorus and sil
