mesoporous aluminas with high thermal stability and their method of preparation.

摘要

mesoporous aluminas with high thermal stability and their preparation process.; The process comprises mixing a source of aluminum with an organic solvent, a nonionic surfactant derived from polyoxides alkene and an amine, and hydrolysis of the aluminum source by adding to the mixture an hydrolyzing solution. engageable materials are obtained both as catalysts and catalyst support for various processes of industrial interest, especially those which run at relatively high temperatures or require harsh conditions of regeneration.
