Steam gasification of oil sludge with calcined olivine

Abstract

Steam gasification of solid/liquid fuels is an efficient method for producing hydrogen and syngas. The purpose of this work was to examine the catalytic behavior of olivine in steam gasification of oil sludge. To achieve this, an Aspen Plus model was developed based on Gibbs free energy minimization. Results showed that the concentration of H2, CO and CH4 increased with adding the olivine particle, while CO2 showed an opposite trend. With ER increasing from 0.12 to 0.36, H2, CO and CH4 decreased significantly, while CO2 increased from 10.97 to 21.87. ER is an important parameter in the gasification process.
