The sulfur removing capacities of Al-based sorbents prepared promoted with molybdenum and nickel were tested in various hot coal gas compositions (H2S, CO2, CO, H2 andN2) using a fixed-bed reactor at 650oC. Firstly, the sulfur removing capacities of Al-based sorbents were tested in the Shell and Texaco process conditions. Also, the concentrations of the H2S and CO2 gases were fixed to 1 % and 2 %, and those of H2 and CO gases were changed from 0% to 55%, respectively. The sulfur removing capacity of Al-based sorbent was not affected with the concentration of CO gas. However, the sulfur removing capacity was a little decreased by absence of H2. The results showed that H2 gas. The sulfur removing capacity of Al-based sorbent was not affected by gas condition much more eventhough commercial sulfidation sorbents were affected by H2 and CO gases. |
