چکیده | ||
The anatase TiO2-supported Ni–Cu bimetallic catalyst was prepared by Co-impregnation method and after shaping by three binders (bentonite, polyethylene glycol and poly vinyl alcohol) into extrudes, the effect of calcining temperature (200 °C, 400 °C, 600 °C and 800 °C) and calcining time (1, 3, 5 and 7 h) on the extrudes were investigated. According to the obtained results, the catalyst prepared at calcining temperature of 600 °C and calcining time of 5 h was selected as the optimal catalyst due to its anatase pure phase, high crystallinity and relatively high surface area. The as-prepared shape catalyst was evaluated as a Claus catalyst for conversion of H2S, CS2 and SO2 into elemental sulfur and provides high conversion of H2S 72.67%, CS2 69.77% and SO2 84.78%. The results indicated that the shaped catalyst with 75.50% of gas conversion efficiency is more active than the commercial Claus catalyst with 62.05% of conversion efficiency. | ||
