Title
Preparation of hydrocarbon dispersible HZSM-5 nanocrystals by hydrothermal crystallization of organofunctionalization seeds
Abstract

Organofunctionalization of zeolitic seeds was used to synthesize hydrocarbon dispersible HZSM-5(HDZ) nanocrystals, in which organic groups grafted on seeds not only limit the growth of nanocrystals but also change surface hydrophobicity of nanocrystals. The high dispersion of the prepared HZSM-5 nanocrystals in n-dodecane was observed and further confirmed by TEM. The quasi-homogeneous catalytic cracking of n-dodecane with HDZ showed about 30% improvement in the catalytic activity with organofunctionalization seeds, which is promising for the potential applications in some special fields.
