Title: Method for precisely controlling inlet pore size of zeolite
Inventor: MURAKAMI YUICHI
IPC: C01B39/14
Filed: 1986-01-31
Abstract: PURPOSE:To adjust the amt. of silica to be supported by zeolite and to facilitate the precise control of the inlet pore size of the zeolite, by adjusting the reaction temp. of chemical vapor deposition to a temp. within a fixed range, when silica is supported by zeolite by the chemical vapor deposition method using a silanizing agent. CONSTITUTION:Silica is supported by zeolite by the chemical vapor deposition method using a silanizing agent (e.g. tetramethoxy silane) after evacuating zeolite such as mordenite. In this case, the amt. of silane to be supported is adjusted by regulating the reaction temp. of the chemical vapor deposition in the first vapor-deposition stage to 10-100 deg.C, thus the inlet pore size of the zeolite is controlled precisely. By this method, the supported amt. of silica can be controlled precisely without requiring severe temp. control, and consumption of energy is saved because the process is proceeded at lower temp. The obtd. zeolite is useful suitably as cracking catalyst for petroleum, etc.
