APPLICATION OF MESOPOROUS CRYSTALLINE SILICATES TO A GOOD CATALYST SUPPORT FOR GASOLINE SYNTHESIS

Rapid synthesis of branched alkanes in the gasoline range from propene was conducted using a series reactor. Alkenes in the gasoline range produced on the MFI type H-Fe-silicate packed in the first-stage reactor were successively hydrogenated on various Pt-modified catalysts packed in the second-stage reactor. Even at high space velocity, the selectivity to branched alkanes including cycloalkanes in the gasoline range was greatly increased by adopting the Pt-modified mesoporous silicate, compared with that of Pt-modified MFI type non-metal silicate and/or silica gel having a distribution of pores in the mesoporous range. The mesoporous silicate was synthesized from kanemite by repeated ion-exchange treatment with an aqueous solution of hexadecyltrimethylammonium chloride.
