【摘要】 烷基化反应中一直沿用的催化剂H2 SO4,HF对环境污染较大 ,腐蚀设备与产物分离困难。文中详细讨论了影响固体酸催化剂PW12 在炭化树脂吸附过程中受预处理的影响。通过实验确定此催化剂制备过程中的适宜预处理条件 ,如预处理溶剂 ,预处理溶剂的浓度。并结合理论进行了分析。更多还原

【Abstract】 Existing industrial alkylation processes employ corrosive and environmental hazardous HF and H2SO4 as catalysts The catalysts have many disadvantages such as pollution , corrosion and difficulty of separating the product and the catalyst For these safety and environmental reasons their substitution with a noncorrosive solid catalyst is desirable This research focuses on the adsorption of the PW12 on carbonized resin which has high activity and is environmental friendlyThe relationship between the acid pretreatment and the activity of catalyst has been studied experimentally and the best pretreatment condition was obtained A theoretical analysis is made更多还原
