Abstract
Use of a catalyst composition comprising A) a first component containing oxidic compounds comprising aluminum and silicon with a molar ratio of silicon to aluminum of more than 1) B) a second component containing an oxidic compound of silicon wherein the ratio of the number of acidic sites of component A, determined by temperature programmed desorption with ammonia as a base, to the number of acidic sites of component B, determined under the same conditions, is at least 3: in a process for the catalytic depolymerization of plastics waste.
