Abstract(s)
One of the wastes generated in the tanning industry is hide fleshing, 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 these two materials. Tests were carried out at 750 and 800 °C and the gas obtained was quantified and analyzed by gas chromatography. The results showed that dolomite improves the performance of the gasification process, with an increase in carbon and hydrogen conversion efficiencies, cold gas efficiency and dry gas yield. It was also possible to verify the catalytic capacity of this material in the cracking of hydrocarbons and its potential to promote the production of H2. In addition, the use of the mixed bed improved the results of the gasification parameters obtained at 800 °C without compromising the degradation of the dolomite verified at higher temperatures.
