Water Gas Shift Reaction Characteristics Using Syngas from Waste Gasification
Journal Title: International Journal of Engineering and Science Invention - Year 2017, Vol 6, Issue 5
Abstract
The characteristics of a high temperature water gas shift reaction over a commercial Fe-based catalyst using syngas from waste gasification were investigated using lab equipment tests and found to be feasible for producing valuable chemical products. The CO conversion and H2/CO ratio were observed using various values for the gas hourly space velocity(GHSV), steam/CO ratio, and temperature. The CO conversion and H2/CO ratio increased with increasing temperature, increasing steam/CO ratio and decreasing SV. The CO conversion values were 32.95% and 46.84% and the H2/CO ratios were 1.8 and 2.09 with temperatures of 350 C and 400C, respectively, when the steam/CO ratio was 2.4 and SV was 458 h-1 . The H2/CO ratio and CO conversion were 1.42 and 30.14%, respectively, when the steam/CO ratio was 1.45, and increased with an increase in the steam/CO ratio. The H2/CO ratio increased to 2.36 and the CO conversion increased to 51.70% when the steam/CO ratio was 3.44. However, the increase in the CO conversion was insignificant when the steam/CO ratio was greater than 2.9.
