PROCESS FOR PREPARING A CATALYST

摘要

A process for the preparation of a catalyst or catalyst precursor for use in a reactor, comprising the steps of: (a) admixing: (i) a catalytically active component or precursor therefor; (ii) one or more carrier materials; (iii) particles of fresh, optionally calcined, catalyst or catalyst precursor material, said particles having a size of 1 to 100 micrometer; and (iv) optionally one or more promoters and/or one or more co-catalysts; (b) shaping the mixture of step (a), and (c) calcining the shaped product of step (b). The introduction of micro-particles into the catalyst or catalyst precursor provides a number of advantages including increased activity, strength, and possible uses of waste material.
