Gasification of biomass in a downdraft reactor
… commission and operate a laboratory scale gasifier system that could be used to investigate the parameters that influence the gasification process. The gasifier is of the open-core variety and is fabricated from 7.5 cm bore quartz glass tubing. Gas cleaning is by a centrifugal contacting …

Fluidized bed gasification of biomass
… at 0.3. The optimum higher heating value of the gas produced was 6.5 MJ/Nm3, while the thermal efficiency was 70%. Reasonably good agreement was found between the experimental results, theoretical results from a thermodynamic model and data from the literature. It was found that the attainment of …

Einbindung von Alkalimetallen bei der Druckkohlensstaubfeuerung
… cycles with efficiencies > 50%, in which the gases from the coal combustion are used to drive a gas turbine. A mayor problem of the PPCC is the high alkali content of the hot flue gases. The alkalis released during coal combustion can react with gaseous sulphur to alkali sulphates. These …

Short-term supply chain management in upstream natural gas systems
Natural gas supply chain planning and optimization is important to ensure security and reliability of natural gas supply. However, it is challenging due to the distinctive features of natural gas supply chains. These features arise from the low volumetric energy density of natural gas and the …

Hydrothermal gasification of human feces as an alternative means of waste mitigation and hydrogen production
Non-catalytic and catalytic gasification have been recently studied as a means of converting waste biomass into value-added gaseous products while concomitantly minimizing the emission of harmful pollutants. With the incorporation of a homogeneous or heterogeneous catalyst, gas products with a …

Enhanced anaerobic digestion of combined wastewater sludges through solubilization of waste activated sludge
… reflected in a higher methane content of the gas. The effect of solubilizing the WAS, prior to digestion, was also reflected in a higher unit gas production (L/kg VSS reduced) in both experimental units. Results obtained in the second phase proved that WAS pretreatment enhanced volatile mass …

Critical Analysis of Pyrolysis and Gasification Applied to Waste Fractions with Growing Energetic Content
… alternative processes such as pyrolysis and gasification. Over more the development of an original integrated municipal solid waste scenario model that integrates the experimental results obtained in the thesis have a practical meaning suitable for large scale application. The experimental …
