Biomass has great potential as a clean, renewable feedstock for producing modern energy carriers. This paper focuses on … the process of biomass gasification, where the synthesis gas may subsequently be used for the production of electricity …, fuels and chemicals. The gasifier is one of the least-efficient unit operations in the whole biomass-to-energy technology …

The best catalysts for promoting char gasification are Group I metals, particularly lithium and potassium, although … other metals are active to a lesser extent. The most prevalent metal naturally in biomass char is potassium, which is not … carbon/potassium complex is frequently proposed. Calcium is the other most common active metal found in biomass, but is far …

In this work, a possible way for partial CO2 emissions reduction from gas turbine exhausts by co-firing with biomass is … to produce syngas to mix with natural gas fuel. As biomass is a CO2 neutral fuel, the fraction of replaced natural gas is …

The paper deals with waste gasification as a technology allowing for indirect co-firing of large quantities of … biodegradable wastes in coal-fired power boilers. In contrast to common landfilling and direct co-firing, gasification of wastes … partly retained in the gasification residues. …

gasification process of a particular feedstock. In total four models were tested in order to determine the syngas composition. One … determined using published experimental data. The other two models, M3 and M4 were based in correlations, while model M4 was … based in correlations to determine the equilibrium constants, model M3 was based in correlations that relate the H2, CO and …

compared with biomass utilization via (IGCC) integrated gasification combined cycle electrical production. In the IGCC scenario …Use of agricultural biomass (switchgrass, prairie grasses) through Fischer–Tropsch (FT) conversion to liquid fuels is …, biomass is co-fired with coal, with biomass comprising 10% of the fuel input by energy content. In this case, the displaced …

This paper presents an exergy analysis of SNG production via indirect gasification of various biomass feedstock …, including virgin (woody) biomass as well as waste biomass (municipal solid waste and sludge). In indirect gasification heat … needed for endothermic gasification reactions is produced by burning char in a separate combustion section of the gasifier …

small–medium scale plants including a realistic biomass gasification model. The model provides five different configurations …The present paper develops a simple but rigorous trigeneration plant model for designing, optimizing and simulating … internal combustion engine and different kinds of absorption chiller (single- and double-effect) modeled using the …

In industrialized countries, it is expected that the future generation of bioenergy will be from the direct combustion … of residues and wastes obtained from biomass. Bioenergy production using woody biomass is a fast developing application … method for the separation of unburnt carbon present in bottom ash obtained from a fixed-bed combustion system, followed by …

Presently, the biomass gasification and centralised gas-supply system fed by crop stalks is still at the stage of … experimental results, the resources-utilisation way of biomass tar from crop stalks and the key technology of biomass gas …
