Alkylation catalyst, its preparation and use

摘要

Process for the preparation of a catalyst comprising the steps of: (a) calcining solid acid-containing particles at a temperature in the range of 400-575°C, (b) incorporating a Group VIII noble metal into the calcined particles to form noble metal-containing particles, and (c) calcining the noble metal-containing particles at a temperature in the range of 350-600°C. The use of two calcination steps in the above temperature ranges results in alkylation catalysts with improved performance.
