A、X、Y型分子筛
A、X、Y型分子筛
A, X and Y-type Molecular Sieves
中文说明：
4A分子筛采用特殊工艺制备，具有结晶完善、选择性吸附、深度干燥等特性，无毒、无味，具有较好流动性，是制备3A、5A分子筛的原粉。
A、X型分子筛在气体、液体及有机物的干燥、净化、分离、提纯方面有着广泛应用；Y型分子筛主要用于制备石油化工行业的催化裂化、加氢裂化等催化剂。
英文说明：
4A type Molecular Sieves is special processed, with the characters of perfect crystallization, choice adsorption, deep dry, non-toxic, tasteless and good fluidity. It's the raw material of 3A, 5A molecular sieves.
A, X-type zeolite is widely used in the drying, cleaning, separation and purification of gas, liquids and organics. Y-type zeolite is mainly used in petrochemical industry, as catalytic cracking and hydrogenation catalysts.
