Estimation of biofuels produced by pyrolysis of coffee husk

"The increasing consumption of energy around the world, along with pollution and climate changes caused by the use of fossil fuels, has generated extensive research and usage of cleaner alternative energy sources. Agro-industrial residue biomasses are one of such sources, as they can be used as feedstock in different processes for the production of alternative fuels. Liquid fuels similar to petroleum refined products can be obtained through Pyrolysis. The objective of this research was to study the potential of Coffe Husk (CH) as feedstock for the production of alternative liquid fuels employing pyrolysis. Samples of CH were thermochemically characterized using ultimate, proximate, and thermogravimetric analyses. Parametric experimental studies on heating rate, final pyrolysis temperature, and particle size were carried out in a fixed-bed pyrolysis reactor, in order to estimate their effects on production yields and thermochemical characteristics of bio-fuels produced through pyrolysis of Colombian CH. Similarly, a computational study was conducted in order to obtain a numerical model to estimate the temperature profiles of the fixed-bed reactor and the composition of gases leaving the reactor."--Tomado del Formato de Documento de Grado
