“…The char is gasified in the range of 700 • C and 1000 • C to deliver syngas. Producer gas or syngas is produced during the process with a calorific value of 4.0 to 5.0 MJ/m 3 (Kosov et al, 2015).…”

“…Thus, the designed unit has a high efficiency of energy conversion of woody biomass into synthesis gas, but it has a low thermal efficiency. The main ways to increase efficiency are to increase the degree of using biomass energy and reduce heat losses with the flue gases [22,23]. The problem of reducing heat losses with the flue gases can be solved both by increasing the efficiency of heat exchange processes inside the unit (improving the flow parts of heat exchangers by using developed fins and optimizing the geometry of the coolant channels), and by recuperating part of the thermal energy of flue gases for heating air, which then goes into the solid fuel furnace for combustion.…”

The widespread adoption of biomass as an energy fuel is hindered by a number of its significant drawbacks, such as low heating value, low ash melting point, low bulk density etc. Technological solutions that allow to fully overcome these shortcomings and ensure high economic performance have not yet been proposed, although there is a significant demand for them. A new technology for thermal processing of biomass into gas fuel, based on the pyrolysis process, has been developed at the Joint Institute for High Temperatures of the Russian Academy of Sciences (JIHT RAS). The degree of energy conversion of the processed raw materials in the proposed technology is about 75%. The gas fuel yield is ∼1.3 m3/kg of biomass, and its heating value, on average, is 11 MJ/m3. The content of the liquid phase in the energy gas obtained by the developed technology is not more than 50 mg/m3. The gas produced by the technology under consideration on average consists of 90% hydrogen and carbon monoxide. According to existing standards, this gas can be used as a fuel for mini-CHP with gas-piston engines. A promising direction for using this gas is the production of liquid motor fuels.

“…The cost contingency is considered to have a triangular distribution with a lower limit, mode, and upper limit of 2, 4, and 6 US$/kW/year [40], respectively. The electrical efficiency of gas engine is considered to have a triangular distribution with a lower limit, mode, and upper limit of 25%, 30%, and 35%, respectively [42]. The syngas to power conversion efficiency is typically about 25% [43].…”

The management and disposal of livestock manure has become one of the top environmental issues at a global scale in line with the tremendous growth of poultry industry over the past decades. In this work, a potential alternative method for the disposal of chicken manure from Singapore local hen layer farms was studied. Gasification was proposed as the green technology to convert chicken manure into clean energy. Through gasification experiments in a 10 kW fixed bed downdraft gasifier, it was found that chicken manure was indeed a compatible feedstock for gasification in the presence of wood waste. The co-gasification of 30 wt% chicken manure and 70 wt% wood waste produced syngas of comparable quality to that of gasification of pure wood waste, with a syngas lower heating value (LHV) of 5.23 MJ/Nm 3 and 4.68 MJ/Nm 3 , respectively. Furthermore, the capability of the gasification derived biochar in the removal of an emerging contaminant (artificial sweetener such as Acesulfame, Saccharin and Cyclamate) via adsorption was also conducted in the second part of this study. The results showed that the biochar was effective in the removal of the contaminant and the mechanism of adsorption of artificial sweetener by biochar was postulated to be likely via electrostatic interaction as well as specific interaction. Finally, we conducted a cost-benefit analysis for the deployment of a gasification system in a hen layer farm using a Monte Carlo simulation model.
