“…When high quantities of moisture are present in the initial RDF, the oxidant supply rate must be enhanced to generate sufficient heat to sustain the gasification reaction, resulting in lower syngas heating value (Materazzi et al, 2016a). As temperature within the bed has to be limited to below ash softening point, upstream oxygen enrichment can also be used, although issues arise for the potential hazards associated with oxygen-rich mixtures at high temperatures (Leclerc and Larachi, 2015).…”

“…Allothermal gasification processes will typically use steam, or in future CO2, as gasification agents in an externally heated reactor, fast internally circulated fluidised beds (FICFB) or dual fluidised beds (DFB) (Wilk et al, 2011;Leclerc and Larachi, 2015). In this latter configuration, air is used to burn char and/or secondary fuels in a separate chamber to provide heat to an inert bed material (e.g.…”

Hydrogen is seen as a key element of the future energy mix because it does not generate greenhouse gas emissions at the point of use. Understanding the technologies that can generate low carbon hydrogen is essential in planning the development of future gas networks and energy generation via fuel cells. One promising approach is hydrogen production by gasification of waste, referred to as biohydrogen. This paper summarises work undertaken to design a commercial Waste-to-Hydrogen (WtH2) plant, which includes an assessment of future markets for hydrogen, the identification of an appropriate scale for the plants, and development of specifications for process design and output streams. An experimental programme was undertaken to demonstrate bioH2 production from refuse derived fuel (RDF) at pilot scale and provided experimental data to underpin commercial designs. On this basis, a reference design for small commercial plants was developed for bioH2 production for heating and transport utilisation. A preliminary carbon assessment shows that carbon savings for 2 biohydrogen in a commercial scale are more than four times greater than alternative technologies.

“…The H2:CO ratio is important for further catalytic hydrogenation to bio-hydrocarbons and this ratio in case of oxygen/steam gasification will be in the order of 1.0 to 1.5 depended on biomass steam ratio [48]. As temperature within the bed has to be limited to below ash softening point, upstream oxygen enrichment can also be used, although issues arise for the potential hazards associated with oxygen-rich mixtures at high temperatures [49].…”

This work explores the use of advanced thermal technologies for the conversion of refuse derived fuel prepared from MSW into clean syngas suitable for catalytic transformation into light hydrocarbon products. In particular, the possibilities for the specific production of C1-C4 hydrocarbons utilising a good quality syngas produced by two-stage plasma assisted gasification method are investigated. A number of catalytic tests were prepared with modified chemistry to evaluate the preliminary component activities on real waste-derived syngas. C1-C4 paraffines formed in all cases as a main products, with different product distribution for different conditions examined (up to 95% bioSNG on hydrocarbon product for supported nickel, 40% bioLPG for Cu-Zn/ZSM-5 catalysts mix). CO2 was the main byproduct with outlet concentrations ranging from 10 to 50% in volume. When increasing H2:CO in the syngas by external addition of hydrogen, CO conversion increases, as well as paraffin selectivity and hydrocarbons yield. Projections on a 65 MW thermal input bioSNG plant show that if 40 MW of electrical output from renewable sources are used to power a PEM stack during high power availability, the production of bioSNG could be increased by more than 33%, with a simultaneous reduction in CO2 emissions of more than 43%.
