摘要:
There is provided a hydrocarbon conversion process and a process for sorbing a sorbate wherein said conversion and sorption process each comprises the use of a porous material. A process for preparing this material involves adding an amphiphilic compound to the reaction mixture for preparing a crystalline oxide. The amphiphilic compound may be a quaternary ammonium cationic surfactant. These surfactants may be in the form of lamellar liquid crystals, and may function as templates for the formation of the present mesoporous oxide materials.
