“…Water is not only a reactant involved in the reaction, but also a catalyst with significant impacts on the supercritical water gasification (SCWG) reaction process. Using supercritical water for biomass gasification is attracting growing interest for H2 and/or CH4 production and much progress has been made in the technical aspects of the processes, because it is safe, non-toxic, readily available, inexpensive, and environmentally-benign (Kruse, 2008;Guo et al, 2010;Heidenreich and Foscolo, 2015). Furthermore, SCWG is applied to wet biomass without the need for pre-drying, which is a major advantage over conventional gasification techniques.…”

Please cite this article as: Farzad S., Mandegari M.A., Görgens J.F. A critical review on biomass gasification, co-gasification, and their environmental assessments. Biofuel Research Journal 12 (2016) HIGHLIGHTSConventional and new gasification technologies were compared. Studies dealing with co-gasification of different feedstocks were summarized. Life cycle assessments of biomass gasification and co-gasification were studied. Gasification is an efficient process to obtain valuable products from biomass with several potential applications, which has received increasing attention over the last decades. Further development of gasification technology requires innovative and economical gasification methods with high efficiencies. Various conventional mechanisms of biomass gasification as well as new technologies are discussed in this paper. Furthermore, co-gasification of biomass and coal as an efficient method to protect the environment by reduction of greenhouse gas (GHG) emissions has been comparatively discussed. In fact, the increasing attention to renewable resources is driven by the climate change due to GHG emissions caused by the widespread utilization of conventional fossil fuels, while biomass gasification is considered as a potentially sustainable and environmentally-friendly technology. Nevertheless, social and environmental aspects should also be taken into account when designing such facilities, to guarantee the sustainable use of biomass. This paper also reviews the life cycle assessment (LCA) studies conducted on biomass gasification, considering different technologies and various feedstocks. ARTICLE INFO ABSTRACT

“…At reaction temperatures below 450 °C, CH4 is the main component in the produced gas, whereas at reaction temperatures above 600 °C hydrogen is dominant. At temperatures above 600 °C, water is a strong oxidant and reacts with the carbon and releases hydrogen (Guo et al, 2010;Heidenreich and Foscolo, 2015).…”

Hydrogen is notable for its unique properties making it the most viable alternative fuel for electricity generation and engine power. This element is highly abundant and is being used in numerous applications industrially. But hydrogen can be an important source of fuel and with the proper knowledge of its different technologies, innovations for hydrogen fuel production can then be addressed. Steam reforming of natural gas is the widely used hydrogen production technology. But environmentally safe production had been a pressing issue. Hence, a shift to a cleaner and more sustainable primary energy source is very essential. This paper gives brief background of the different hydrogen production techniques using two primary energy resources as well as the developments, the gaps, and the further improvements needed to be made. Note however, that comprehensive R&D details should be sought in specialist papers for a more thorough background. The sustainability of hydrogen production technology lies from where it is produced, thus this paper also aims to highlight the hydrogen fuel production from biomass citing its developments and its potential for high hydrogen yield.

H2SO4 and NaOH Pretreatment to Enhance Bio-Oil Yield of Pine Wood Liquefaction in Methanol

et al. 2017

Pine wood was pretreated with H2SO4 and NaOH, followed by liquefaction in methanol at temperatures ranging from 200 to 350 °C, to produce biooil. Composition analysis and scanning electron microscopy (SEM) observation were performed to study the impact of the pretreatment on the pine wood structure. The SEM images showed that the structures of the samples were destroyed by pretreatment. After being pretreated by H2SO4, the size of holes generated was smaller than that with pretreatment by NaOH. Furthermore, the influences of the temperature, methanol content, and residence time on the yield of the water-soluble fraction (WS), ethersoluble fraction (ES), and bio-oil were determined. Shorter residence time and higher amounts of methanol favored the products of WS, ES, and biooil. Gas chromatography-mass spectrometry (GC-MS) analysis showed that phenols, ketones, aromatics, and aldehydes are the main components of bio-oil.
