Abstract
There is provided a catalyst comprising a heteropoly acid, such as phosphotungstic acid, supported on a mesoporous crystalline material, such as M41S. A particular form of this M41S support is designated as MCM-41. There is also provided a method for preparing this catalyst by impregnating the heteropoly acid on the support. There is also provided a process for using this catalyst to catalyze acid catalyzed reactions, such as the isomerization of paraffins and the alkylation of aromatics.
Claims9
A process for converting an organic compound, said process comprising contacting an organic compound with a catalyst under sufficient conversion conditions, said catalyst comprising a heteropoly acid supported on a porous support material comprising an inorganic, porous, crystalline phase material having pores with diameters of at least about 13 Angstroms and which exhibits, after calcination, an X-ray diffraction pattern with at least one d-spacing greater than about 18 Angstroms with a relative intensity of 100.
An isomerization process comprising contacting a feed comprising a C.sub.4 -C.sub.9 linear paraffin with a catalyst under sufficient conversion conditions, said catalyst comprising a heteropoly acid supported on a porous support material comprising an inorganic, porous, crystalline phase material having pores with diameters of at least about 13 Angstroms and which exhibits, after calcination, an X-ray diffraction pattern with at least one d-spacing greater than about 18 Angstroms with a relative intensity of 100.
An aromatic alkylation process comprising contacting an aromatic with an alkylating agent and a catalyst under sufficient alkylation conditions, said catalyst comprising a heteropoly acid supported on a porous support material comprising an inorganic, porous, crystalline phase material having pores with diameters of at least about 13 Angstroms and which exhibits, after calcination, an X-ray diffraction pattern with at least one d-spacing greater than about 18 Angstroms with a relative intensity of 100.
An isoparaffin/olefin alkylation process which comprises contacting an isoparaffin and an olefin with a catalyst under sufficient alkylation conditions, said catalyst comprising a heteropoly acid supported on a porous support material comprising an inorganic, porous, crystalline phase material having pores with diameters of at least about 13 Angstroms and which exhibits, after calcination, an X-ray diffraction pattern with at least one d-spacing greater than about 18 Angstroms with a relative intensity of 100.
