Abstract
To enhance the performance of SEWGS system by holding the WGS catalyst in a SEWGS reactor, a spring type bed insert was developed. In this study, effects of operating variables such as steam/CO ratio, gas velocity, syngas concentration on CO conversion were investigated in a fluidized bed reactor using the spring type bed insert to hold the WGS catalyst as tablet shape. CO conversion increased initially as the steam/CO ratio increased. But further increment of the steam/CO ratio caused decreasing of CO conversion because of increment of gas velocity and decrement of syngas concentration. Moreover, CO conversion decreased as the gas velocity increased and the syngas concentration decreased at the same steam/CO ratio. Continuous operation up to 48 hours (2 days) was carried out to check reactivity decay of WGS catalyst supported by spring type bed insert. The average CO conversion was 99.04% and we could conclude that the WGS reactivity at those conditions was maintained up to 48 hours.
