PREPARATION OF γ-ALUMINA AS A SUITABLE SUPPORT FOR HDS CATALYST

In this article γ-Alumina as a favorable hydrodesulphurization (HDS) catalyst support was experimentally synthesized. Aluminum sulfate and sodium aluminate were used as raw materials whose aqueous solutions were reacted to produce aluminum oxide gel. The resulting gel is phase-separated, filtrated, extruded and finally dried to form solid γ-Alumina. In order to measure the surface area of produced sample, liquid nitrogen adsorption/desorption isotherms were achieved and introduced in the well-known equation of BET. The results show that the surface area of produced support in comparison with the similar commercial types was in the moderate range.
