Effect of mass flow rate and temperature on the gasification of animal fat
Araújo, A.L.; Paiva, E.; Silva, F.T.; Ribeiro, A.; Campos, J.B.L.M.; Pilão, R.M.In this work, gasification of animal fat was studied. Tests were performed with an emulsion of fat and water and temperature and mass flow rate effects were evaluated. Gas chromatography was used to analyze the composition of producer gas. Carbon and hydrogen conversion efficiencies, dry gas yield, cold gas efficiency, and higher heating value of producer gas were determined. The results showed that temperature...
Co-pyrolysis of brown macroalgae and pinecones in a fixed bed reactor
Silva, F.T.; Nascimento, M.; Pilão, R. M.; Neto, M.P.; Ribeiro, A.M.This study presents results on the slow co-pyrolysis of Laminaria digitata (LD) and pinecones (PC), at an average temperature of 560 °C, for mass ratios LD/PC of 100/0, 50/50, 30/70, 10/90 and 0/100. The biochar yields varied from 35.3 to 31.2 %, for bio-oils, the yields were in the range of 23.3 to 39.9 %, and for the gas phase, between 41.4 to 28.9 %, as the amount of PC increased in the feeding mixture. The ...
Gasification of animal fat using dolomite as particle bed in a downdraft fixed ...
Pilão, R.; Araujo, A.L.; Silva, F.T.; Ribeiro, A.M.; Campos, J.B.L.M.One of the wastes generated in the tanning industry is hide fleshings, which contains 40% of animal fat, currently being deposited in landfills. The objective of this work was to study the catalytic capacity of dolomite in the gasification of this waste. The tests were carried out in a downflow fixed bed reactor using steam as gasification agent and used as bed of particles, alumina, dolomite and a mixture of t...
Effect of temperature on the gasification of animal fat: Preliminary results
Araujo, A.L.; Silva, F.T.; Ribeiro, A.C.; Campos, J.B.L.M.; Pilão, R.M.In this work, steam reforming of animal fat was studied using a fixed bed reactor. The effect of temperature was evaluated in the range of 750 and 950°C. Gas chromatography was used to analyze the gas sample and determine the gas composition. The results showed that the temperature greatly influences the gas composition and gasification process. The gasification parameters increased with the temperature rise, a...
