Abstract
A catalyst comprising, in weight % with respect to the total catalyst weight 0.1% to 60% (expressed as the % by weight of oxide) of at least one hydro-dehydrogenating metal selected from the group formed by group VIB and VIII metals; 0.1% to 99% of at least one amorphous or low crystallinity porous matrix; 0.1% to 99.7% of beta zeolite; 0.1% to 20% (expressed as the % by weight of oxide) of at least one promoter element selected from the group formed by boron, silicon and phosphorous; 0 to 20% of at least one halogen; 0 to 20% (expressed as the % by weight of oxide) of at least one group VIIB element, the catalyst being especially useful for cracking hydrocarbon feeds.
