TL;DR: In this article, thermogravimetric (TG) analyses along with thermal and catalytic fast pyrolysis experiments of cellulose, hemicellulose, lignin and their mixtures were carried out in order to investigate their pyroolysis products and whether the prediction of the pyrolys behavior of a certain lignocellulosic biomass feedstock is possible, when its content in these three constituents is known.

TL;DR: In this paper, an equilibrium, commercial diluted ZSM-5 catalyst was used as the base case, in comparison with a series of nickel (Ni) and cobalt (Co) modified variants at varying metal loading.

TL;DR: In-situ catalytic upgrading of biomass fast pyrolysis vapors was performed in a fixed bed bench-scale reactor at 500°C, for catalyst screening purposes, showing the most balanced performance having a moderate selectivity towards hydrocarbons, reducing undesirable compounds and producing organic liquid products at acceptable yields.

TL;DR: In this article, the authors investigated low-cost, naturally derived basic MgO materials as catalysts for the catalytic fast pyrolysis of lignocellulosic biomass as alternatives to classical acidic zeolite catalysts.

TL;DR: In this article, the authors evaluated commercial ZSM-5 catalysts (diluted with a silica-alumina matrix) in the in situ upgrading of lignocellulosic biomass pyrolysis vapours and the validation of their bench-scale reactor performance in a pilot scale circulating fluidized bed (CFB), and further promoted with cobalt (Co, 5% wt%).
