Abstract
In this work the combined effect of temperature and gasifying agent composition (oxygen and steam concentrations) on gas production and other process parameters, during high pressure coal gasification was studied. Temperature and oxygen concentration were the most influential variables during the gasification process. As temperature increases, there is an improvement in coal conversion and in the production of H{sub 2}+CO. Higher levels of oxygen produced more CO{sub 2} and less H{sub 2}, as expected. The increase of the steam content in the reactive gas led to an increase in H{sub 2} and a decrease in CO production. In addition, co-gasification tests of binary (coal-petcoke) and ternary (coal-petcoke-biomass) blends were conducted in order to study the effect of blending on gas production and carbon conversion. 10 refs., 3 figs., 3 tabs.
