Pyrolysis of Wood/Biomass for Bio-oil: A Critical Review
TLDR
A review of the recent developments in the wood pyrolysis and reports the characteristics of the resulting bio-oils, which are the main products of fast wood pyrotechnics, can be found in this paper.Abstract:
Fast pyrolysis utilizes biomass to produce a product that is used both as an energy source and a feedstock for chemical production. Considerable efforts have been made to convert wood biomass to liquid fuels and chemicals since the oil crisis in mid-1970s. This review focuses on the recent developments in the wood pyrolysis and reports the characteristics of the resulting bio-oils, which are the main products of fast wood pyrolysis. Virtually any form of biomass can be considered for fast pyrolysis. Most work has been performed on wood, because of its consistency and comparability between tests. However, nearly 100 types of biomass have been tested, ranging from agricultural wastes such as straw, olive pits, and nut shells to energy crops such as miscanthus and sorghum. Forestry wastes such as bark and thinnings and other solid wastes, including sewage sludge and leather wastes, have also been studied. In this review, the main (although not exclusive) emphasis has been given to wood. The literature on woo...read more

Oxygen-removal of dibenzofuran as a model compound in biomass derived bio-oil on nickel phosphide catalysts: Role of phosphorus
Juan Antonio Cecilia,Antonia Infantes-Molina,Enrique Rodríguez-Castellón,Antonio Jiménez-López,S. T. Oyama,S. T. Oyama +5 more
TL;DR: In this paper, the formation of the nickel phosphide phase as well as the textural, structural and acidic properties of the catalysts were evaluated by X-ray fluorescence (XRFS), H 2 -temperature programmed reduction (H 2 -TPR), X-Ray diffraction (XRD), CO chemisorption at 35-°C, N 2 adsorption-desorption isotherms at −196 ǫ c, NH 3 -tPD and elemental analysis (CNHS).
