Fast pyrolysis kinetics of lignocellulosic biomass of varying compositions

Energy Conversion and Management: X, 2021
This study is focused on evaluating the apparent kinetics of fast pyrolysis of different lignocellulosic biomass viz, rice straw, pine wood and empty fruit bunch. The goal of the study is to investigate the effect of biomass composition on kinetics, time

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

Advanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Catalytic Fast Pyrolysis of Biomass Impregnated with Potassium Phosphate in a Hydrogen Atmosphere for the Production of Phenol and Activated Carbon

Frontiers in Chemistry, 2018
A new technique was proposed to co-produce phenol and activated carbon (AC) from catalytic fast pyrolysis of biomass impregnated with K3PO4 in a hydrogen atmosphere, followed by activation of the pyrolytic solid residues.

Stepwise Fast Pyrolysis of Pine Wood

Energy & Fuels, 2012
This paper reports the yields and product composition obtained from the stepwise pyrolysis of pine wood in a fluidized bed reactor. The first step temperature was varied between 260 °C and 360 °C. After the first step, the solid residue was cooled to ambient temperature and pyrolyzed again at 530 °C.

BIO-OIL FROM CATALYTIC AND NON-CATALYTIC PYROLYSIS OF GLYCEROL [PDF]

, 2010
The rapid increasing of fuel consumption cause the resource is depleting fast and threat the continuation of energy supply. That is the reason why petroleum price is rising. Therefore, the variation of alternative fuels are being exploited to sustain the

Fast pyrolysis of hemicelluloses into short-chain acids: An investigation on concerted mechanisms [PDF]

, 2020
The nature of main primary mechanisms involved in lignocellulosic fast pyrolysis is often assumed to be radical mecha-nisms. Here we demonstrated that thermal depolymerization of native hemicelluloses can undergo several primary and secondary concerted ...

Polarizable Vanadium Dipoles Promote Water Dissociation on Vanadium‐Based Metal Organic Framework

Advanced Functional Materials, EarlyView.
The polarization of unpaired V 3d electrons weakens the H─O bond to improve water dissociation by the dual Vδ+:O─H and Pλ−:H─O coupling hydrogen bonds formation and relaxation. P@V‐MOF electrocatalyst shows low overpotentials (94 mV in acid, 178 mV in neutral, and 77 mV in alkaline solutions) with excellent stability for effective overall water ...
