Catalytic adsorber for arsenic collection and selective hydrodesulphurisation of catalytic cracked gasoline

摘要

Catalytic adsorbent, comprises a metal (M1) from group VIB, and metals (M3 and M2) from group VIII deposited on a porous carrier, where: a molar ratio of the metal (M2+M3)/M1 is 1-6; the amount of M1 is 3-14 wt.%; the amount of M2 is 1-20 wt.%; and the amount of M3 is 5-28 wt.%. An independent claim is included for process for hydrodesulfurization of a hydrocarbon feedstock, comprising contacting hydrogen with hydrocarbon feedstock in presence of the catalytic adsorbent.
