TL;DR: In this paper, the apparent activation energy needed to break the bonds of hemicelluloses and cellulose of rice husk and elephant grass during the thermal conversion was evaluated according to the kinetics models of Flynn and Wall and Model Free Kinetics developed by Vyazovkin.

TL;DR: In this article, the Elephant Grass (Pennisetum purpureum Schum) was pretreated by two independent processes, through washing with hot water (W-EG) and acid solution (AW-EG), to improve its energy properties to apply it in a thermochemical process conversion into fuel.

TL;DR: In this paper, the influence of the concentrations of nickel and iron and the reaction temperature in catalysts tested in the dry reforming of methane, using a factorial design to optimize the H2 yield (Y H 2 ).

TL;DR: In this paper, a molecular sieves MCM-41 was synthesized from rice husk ash (RHA) as alternative sources of silica, which was characterized by X-ray powder diffraction, FTIR, TG/DTG and surface area determination by the BET method.

TL;DR: In this article, the catalytic pyrolysis products of Elephant Grass (EG) using WO 3 catalysts supported on rice husk ash (RHA) silica and RHA-MCM-41, being low cost materials derived from agro industrial waste, and evaluate the catalysts activity in the formation of deoxygenated compounds.
