Abstract
The study proposes a novel approach for the synthesis of granular MCM-22 zeolite with a hierarchical micro–meso–macroporous structure. This approach is based on the crystallization of zeolite granules consisting of powdered MCM-22 and synthetic amorphous aluminosilicate. The synthesized material had 97% crystallinity and volumes of micro-, meso-, and macropores of 0.18, 0.22, and 0.46 cm3/g, respectively. The H-form of the hierarchical MCM-22 exhibited high activity and selectivity in dimerization of α-methylstyrene.
期刊介绍：
Petroleum Chemistry (Neftekhimiya), founded in 1961, offers original papers on and reviews of theoretical and experimental studies concerned with current problems of petroleum chemistry and processing such as chemical composition of crude oils and natural gas liquids; petroleum refining (cracking, hydrocracking, and catalytic reforming); catalysts for petrochemical processes (hydrogenation, isomerization, oxidation, hydroformylation, etc.); activation and catalytic transformation of hydrocarbons and other components of petroleum, natural gas, and other complex organic mixtures; new petrochemicals including lubricants and additives; environmental problems; and information on scientific meetings relevant to these areas.
Petroleum Chemistry publishes articles on these topics from members of the scientific community of the former Soviet Union.
