Resumo(s)
In this work, the co-gasification of treated crude glycerol and animal fat was studied using steam as the gasifying agent. Tests were performed in a downflow fixed bed reactor with a bed composed of catalyst particles of dolomite. The gasification process was studied using a mixture with 59% of glycerol, 3% of fat and 38% of water and tests were carried out at 700 ºC and 750 ºC.
The producer gas was quantified and analysed by gas chromatography obtaining, for the tested temperatures, between 48% and 47% of H2, about 13% of CO, 11% of CH4 and CO2 content between 30% and 27%. The results showed that the use of dolomite as a catalyst promotes the production of a gas rich in H2 and CO2.
The results also show that the gasification parameters increase with temperature having obtained at the maximum working temperature a gas production yield of 0.92 m3/kg at 750ºC, a cold gas production efficiency of 70.6% and for the carbon and hydrogen conversion efficiencies the values obtained were 58.0 % and 40.9% respectively.
