TL;DR: In situ catalytic upgrading of biomass derived fast pyrolysis vapours in a fixed bed reactor using mesoporous materials is described in this article, where a fixed-bed reactor is used.
262 citations
TL;DR: In this article, the catalytic properties of Al-MCM-41 type mesoporous catalysts were modified by pore enlargement that allows the processing of larger molecules and by introduction of Cu cations into the structure.
254 citations
TL;DR: In this article, a series of x Cr SBA-15 and x Cr 2 O 3 catalysts were used for dehydrogenation of propane (DHP) to gain a better understanding of the nature and distribution of Cr species and their catalytic function.
149 citations
TL;DR: In this article, multiphase light scattering and transient-dynamic rheometry were used in combination in order to control the stability, rheology and gelation of aqueous Aerosil 200 suspensions with regard to the influence of pH, particle and electrolyte concentrations.
95 citations
TL;DR: In this paper, a review of magnetically driven methods available for nanoparticle recovery, or nanoparticle purification, are discussed with respect to their efficiency and possibilities for optimization, and safety concerns regarding the use of the nanoparticles in industrial work environments and potential risks of exposure are presented in the last section.

TL;DR: 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...

TL;DR: In this paper, an updated review on fast pyrolysis of biomass for production of a liquid usually referred to as bio-oil is provided, including the major reaction systems.
Abstract: This paper provides an updated review on fast pyrolysis of biomass for production of a liquid usually referred to as bio-oil. The technology of fast pyrolysis is described including the major reaction systems. The primary liquid product is characterised by reference to the many properties that impact on its use. These properties have caused increasingly extensive research to be undertaken to address properties that need modification and this area is reviewed in terms of physical, catalytic and chemical upgrading. Of particular note is the increasing diversity of methods and catalysts and particularly the complexity and sophistication of multi-functional catalyst systems. It is also important to see more companies involved in this technology area and increased take-up of evolving upgrading processes. © 2011 Elsevier Ltd.
