MOLECULAR SIEVE TABLET

摘要

PROBLEM TO BE SOLVED: To provide molecular sieve tablets which are used as a catalyst for the synthesis of methylamines, etc., and has good strength and high catalytic activity. SOLUTION: Molecular sieve powder of 20 wt.% or below in water content and 0.3-0.7 g/cm3 in bulk density is molded into tablets having 0.9-1.2 g/cm3 in density and 400-600 m2/g in specific surface area.
