摘要

A novel sorption-enhanced steam reforming (SESR) process of hot coke oven gas (HCOG) was proposed for tar removal and H_2 amplification, and was studied with the comparison of conventional steam reforming (SCR) process. Both of the processes could remove tar effectively and improve the H_2 amount in the COG obviously. For CSR process, after the temperature and the S/HCOG ratio reached 700°C and 2.4 respectively, the H_2 amplification factor kept 4.30 around, with its concentration less than 75%. However, for SESR process, the H_2 amount and concentration get improved further, with the optimal temperature moving toward low temperature. At 600°C and the S/HCOG ratio of 2.4, the H_2 amplification factor and concentration could reach 4.91 and 97.55% respectively when the CaO/C ratio was 2.0. Under the respective optimal reforming conditions of the two processes, the energy consumption of the SESR process was lower than that of CSR process.
