Often improvements in shipped quality levels can be made by plugging obvious holes in a device’s test suite, sometimes simply by increasi...

Sorption-enhanced gasification (SEG) is a promising route for the conversion of biomass into synthetic fuels. There are important aspects regarding syngas quality (e.g. tar composition and/or gaseous contaminants such as H2S) that may influence scaling-up process and should be assessed. Experiments were performed in 30 kWth bubbling fluidised gasifier to evaluate effect feedstock used, temperat...
