We have studied a high temperature steam gasification process to generate hydrogen-rich fuel gas from woody biomass. In this study, the performance of the gasification system which employs only high temperature steam exceeding 1200 K as the gasifying agent was evaluated in a 1.2 ton/day-scale...

Pilot scale ring and die pelletizing of reed canary grass (Phalaris arundinacea L.) was performed in experimental designs for screening and optimization of pellet quality parameters bulk density and durability and for determination of specific energy consumption under different settings. Control...

Pilot scale pelletizing of torrefied Norway spruce was performed in a factorial design with controlled factors at two levels: material moisture content (11% and 15%) and torrefaction temperature (270 and 300°C), and die temperature as an uncontrolled factor (60–105°C). Compared to commercial...

This paper explored the feasibility of CO2 as alternative gasifying agent of steam to obtain higher thermal efficiency in biomass gasification. The effect of the gasifying agent on gas evolution and thermal efficiency was examined by using a lab scale downdraft gasifier. The results were also...

Torrefaction of plant biomass has the capacity to produce a fuel with increased energy density and homogeneity, but there are reports that it changes the pelletizing properties of the biomass, making it more difficult to obtain high quality pellets. A parametric study was therefore conducted in...

High temperature steam gasification (HTSG) is a gasification technology which utilizes super-heated steam at a temperature above 1273K. This paper addresses the performance analysis of an updraft HTSG gasifier using a numerical model. The experimental data obtained from a demonstration-scale...
