Preparation of Porous Catalyst Support with Gangue of Bauxite Tailing

Abstract:

Porous catalyst support was prepared using gangue of bauxite tailing which was a solid waste material. It was found that the mass ratio of gangue of bauxite and knar clay was 4: 1. The masses of cellulose and water were individually 1 wt% and 25 wt% of the total mass of gangue of bauxite tailing and knar clay. The pore forming agent M was optimum among the selected pore forming agents. The pore forming agent M didn’t residue in support after sintering so that the support wasn’t polluted. The appropriate addition of the pore forming agent M was 4%, and the catalyst support with the porosity of 41.3% was preparated. The appropriate sintering temperature and holding time were 1250 °C and 2.0 h, respectively. Mullite and quartz were the main mineral phase of the porous catalyst support and the catalyst support have good chemical stability and heat-resisting property.
