    摘要： A catalytic composition for use in fluid catalytic cracking has an effective heat capacity of at least about 0.29 BTU/lb. .degree.F. over the range from 950.degree. F. to 1300.degree. F. The composition may include microspheres containing in situ crystallized Y-faujasite and fluidizable particles consisting essentially of dimagnesium borate. The catalytic composition may include a heat retention component selected from the group consisting of dimagnesium borate, aluminum borate, magnesium tetraborate, magnesium orthoborate, lithim aluminum borate, lithium magnesium borate, lithium aluminum silicate, and lithium aluminate.
