摘要：

Co-gasification of bagasse wastes mixed with coal is technically feasible, without major installation changes. The effect of experimental conditions on co-gasification process was analysed, to enhance gas production and improve its composition and energetic content. The rise of bagasse content increased tars and gaseous hydrocarbons contents, which can be reduced by increasing gasification temperature and/or air flow rate. The rise of temperature till 890 degrees C favoured hydrocarbons further reactions and allowed an increase of 45% in hydrogen release and a decrease in gaseous hydrocarbons of 55%. A reduction of around 30% in gaseous hydrocarbons was also achieved by rising O-2/fuel ratio till 0.6 g/g daf, which decreased gas heating value, due to nitrogen diluting effect. Though no significant changes in gaseous hydrocarbons composition were obtained, the presence of dolomite in the fluidised bed had the benefit of decreasing tars content and rising gas yield, being the gas richer in hydrogen content.
