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

Arsenic removal from water/wastewater using adsorbents—A critical review
Dinesh Mohan,Charles U. Pittman +1 more
TL;DR: Strong acids and bases seem to be the best desorbing agents to produce arsenic concentrates, and some commercial adsorbents which include resins, gels, silica, treated silica tested for arsenic removal come out to be superior.

Effect of heating rate on the pyrolysis yields of rapeseed
TL;DR: In this paper, the effect of heating rate on the mass losses from the rapeseed were examined using the derivative thermogravimetric analysis profiles, which showed that important differences on the pyrolytic behavior of rapeseed are observed when heating rate is changed.

Kinetic evidence for five-coordination in AlOH(aq)2+ ion.
Thomas W. Swaddle,Jörgen Rosenqvist,Ping Yu,Eric J. Bylaska,Brian L. Phillips,William H. Casey +5 more
TL;DR: The kinetics of proton and water exchange on aqueous AlIII, coupled with Car-Parrinello simulations, support a five-coordinate Al(H2O)4OH2+ ion as the predominant form of AlOH(aq)2+ under ambient conditions, which contrasts AlIII with other trivalent metal aqua ions, for which there is no evidence for stable pentacoordinate hydrolysis products.
