CATALYST CONTAINING AT LEAST TWO ALUMINIZED ZEOLITES Y AND CONVENTIONAL HYDRO-CONVERSION OF PETROLEUM FRACTION USING THE CATALYST

摘要

PROBLEM TO BE SOLVED: To provide a catalyst capable of performing the hydro-conversion of a petroleum fraction in high selectivity while holding low reaction temp. SOLUTION: A carrier consists of at least one matrix, at least one zeolite Y(Y1) with a crystal parameter of 24.15-24.38Åand at least one zeolite Y(Y2) with a crystal parameter of 24.38 to 24.51Å. A catalyst contains at least one matrix, at least one zeolite Y(Y1) with a crystal parameter of 24.15-24.38Å, at least one zeolite Y(Y2) with a crystal parameter of 24.38-24.51Åand at least one hydrogenating/dehydrogenating element.
