摘要
对国内外甲醇制烯烃催化剂的开发历程及进展进行了综述。开发无毒模板剂或价格低廉的无机模板剂、降低水用量、有效控制分子筛纯度、提高收率、母液的循环利用,是今后甲醇制烯烃工艺催化剂活性组分制备的发展方向。提高流化床甲醇制烯烃工艺中SAPO-34成型催化剂的催化性能、水热稳定性和耐磨强度、控制粒径分布和球形度,改进固定床甲醇制丙烯工艺中ZSM-5分子筛成型催化剂的催化性能、抗结焦性和水热稳定性、提高压碎强度是甲醇制烯烃工业化催化剂的开发方向。
The development and advances in catalysts for typical technology for methanol to olefins are reviewed. The development orientation of active molecular sieve catalyst is to exploit innoxious and low-price inorganic template, lower water usage, control molecular sieve purity, enhance yield and recycle the mother liquid. The development direction for catalysts used in fluidized bed process for typical technology for methanol to olefins is to enhance SAPO-34＇ s catalytic performance, water and thermal stability, abrasive resistance, and to control the attribution of particle size. The development direction for catalysts used in the fixed bed process is to improve the ZSM-5 ＇ s catalytic performance, coke resistance.water and thermal stability and crush intensity.
