Method to remove metals from residuals

A process for the preparation of an olefins-containing mixture of hydrocarbons, which process comprises contacting a hydrocarbonaceous feedstock with a zeolitic catalyst at a temperature above 480.degree. C. during less than 10 seconds, whereby the zeolitic catalyst comprises a mixture of a zeolite I and a zeolite II in a matrix, wherein zeolite I has a pore diameter of 0.3 to 0.7 nanometers and zeolite II has a pore diameter greater than 0.7 nanometers, and wherein the catalyst contains at least 25% by weight of zeolitic material. The invention further relates to a catalyst composition comprising a mixture of a zeolite I and a zeolite II in a matrix material, wherein zeolite I has a pore diameter of 0.3 to 0.7 nanometers, zeolite II has a pore diameter greater than 0.7 nanometers, and the composition contains at least 25% by weight of zeolitic material.
