shape selective catalyst的意思|示意

The olefin conversion of FCC naphtha to produce light olefins over regular carrier catalyst preparated from shape-selective molecular sieve was studied in a regular fixed-bed reactor.

以择形分子筛制备的规整载体催化剂，在规整固定床反应器上，进行催化裂化汽油中烯烃转化产低碳烯烃的裂化反应。

We effectively improve the MMT thermal stability of solid acid catalyst and the shape-selective catalysis by transforming the two-dimensional layered structure to the three-dimensional pore structure.

有效地提高了蒙脱土固体酸催化剂的热稳定性；通过从二维层状结构到三维孔道结构转变，切实提高了材料自身择形催化的特性。
