The aim of this study is to develop a process for the removal of Hg 0 using H 2 S over iron oxides sorbents, which will be located just before the wet desulfurization unit and catalytic COS converter of a coal gasification system. It is necessary to understand the reactions between the iron oxide sorbent and other components of the fuel gas such as H 2 S, CO, H 2 ,...
The characteristics of a novel method for Hg removal using H 2 S and sorbents containing iron oxide were studied. Previously, we have suggested that this method is based on the reaction of Hg and H 2 S over the sorbents to form HgS. However, the reaction mechanism is not well understood. In this work, the characteristics of the Hg removal were studied to clarify the reaction mechanism...
The recycling of waste lubricant oil from automobile industry was found to be best alternative to incineration. Silica (SiO 2 ), alumina (Al 2 O 3 ), silica–alumina (SiO 2 –Al 2 O 3 ) supported iron oxide (10wt% Fe) catalysts were prepared by wet impregnation method and used for the desulphurisation of waste lubricant oil into fuel oil. The extent of...
The dechlorination of chloroorganic compounds from PVC-containing mixed plastic-derived oil was studied over iron oxide and iron oxide-carbon composite catalysts. The catalysts are characterised by nitrogen adsorption and X-ray diffraction. The catalysts are deactivated initially due to the adsorption of HCl gas that is produced during the reaction. Continuous adsorption of HCl on iron oxide leads...
