摘要:
A process for conversion of hydrocarbon feed by contacting the feed with a catalyst containing heteropoly acid supported on a carrier at reaction conditions being effective in the conversion of the feed, wherein the carrier is selected from substantially inert inorganic amorphous or crystalline material, which retains characteristic structure of the heteropoly acid as evidenced by vibration frequencies around 985 and 1008 cmnull1, and which has a surface area larger than 15 m2/g excluding surface area in pores below 15 null in diameter.
摘要:
Method of preparing zeolite single crystals comprising the step of applying a synthesis gel with zeolite precursor composition within pore system and on surface of a particulate matrix material having a predetermined pore structure and particle size; subjecting the precursor composition to crystallising conditions; and isolating porous single crystals of the zeolite by removing the matrix material.
