Claim 15:
16. A method for preparing the alkylation catalyst according to claim 13, comprising the steps of:
i) providing a shaped solid acid catalyst,
ii) loading a metal having a hydrogenation capability onto the solid acid catalyst to obtain a catalyst precursor, and
iii) drying and calcining the catalyst precursor obtained in step ii) to obtain the alkylation catalyst,
wherein the solid acid catalyst has a macropore specific volume in a range of about 0.30-0.50 ml/g, a ratio of macropore specific volume to specific length of catalyst particles in a range of about 1.0-2.5 ml/(g·mm), and a ratio of specific surface area to length of catalyst particles in a range of about 3.40-4.50 m2/mm, wherein the macropore refers to pores having a diameter greater than 50 nm.
