Hydrodesulphurization of gasoils: Advantages of counter-Current gas-Liquid contacting (original) (raw)

2002

Abstract

Hydrodesulphurization (HDS) of gasoils is conventionally carried out in the petroleum industry in co-current trickle bed reactors. The important disadvantage of co-current operation is that the build-up of H2S along the reactor height is detrimental to the desulphurisation reaction; this is because of inhibition effects. In this paper we examine the benefits of carrying out the HDS reaction in a
