用于甲苯甲醇侧链烷基化反应的催化剂及其工艺方法
摘要：
本发明涉及一种用于甲苯甲醇侧链烷基化反应的催化剂及其工艺方法，主要解决现有用于甲苯甲醇侧链烷基化制乙苯和苯乙烯反应的催化剂对甲醇的利用率低、甲苯转化率低以及催化剂稳定性差的问题。本发明通过一种用于甲苯甲醇侧链烷基化反应的催化剂及其工艺方法，该催化剂以改性X或Y分子筛为活性组分，采用碱金属元素中的至少一种，以及稀土元素中的至少一种作为改性组分，催化剂中V元素的质量含量少于900ppm，Ti元素的质量含量少于900ppm，Os元素的质量含量少于900ppm的技术方案，较好地解决了该问题，可用于甲苯甲醇侧链烷基化反应制备乙苯和苯乙烯的工业生产中。
摘要（英）：

The invention relates to a catalyst for alkylation reaction at methylbenzene methanol side and a technical method thereof; the invention mainly solves the problem of low methanol utilization rate, low methylbenzene conversion rate and bad catalyst stability of the catalyst for preparing ethylbenzene and styrene by alkylation reaction at methylbenzene methanol side. Through the catalyst for alkylation reaction at methylbenzene methanol side and the technical method thereof, the catalyst takes modified X or Y molecular sieve as the active component, and adopts at least one of alkali metals and at least one of rare-earth elements as the modifying component; the mass content of V element in the catalyst is less than 900 ppm, the mass content of Ti element is less than 900 ppm, and the mass content of Os element is less than 900 ppm; the technical scheme well solves the problem, and the catalyst and the technical method can be applied to the industrial production of preparing ethylbenzene and styrene by alkylation reaction at methylbenzene methanol side.
