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 …

Biomass as a zero-carbon fuel plays a pivotal role in global sustainable energy
development. Among diverse biomass-based energy utilization methods, biomass steam …

In this work, the co-pyrolysis of Indonesian coal (sub-bituminous) and two types of biomass,
rice straw and Leucaena leucocepha wood, was studied using a drop tube fixed-bed …

Reactions between char and gasifying agents are usually the controlling step and of a core
role for the overall biomass gasification process due to the relatively low reaction rate. Char …

Abstract Chemical Looping Gasification (CLG) is a dual fluidized bed gasification technique
where an oxygen carrier is used as bed material instead of sand. An optimized process …

Active bed materials are in this work investigated for in situ gas upgrading of biomass-
derived gas. Previous research on in situ gas upgrading has focused on assessing gas …

Cogasification of low rank coal with three kinds of biomass, ie, Japanese cedar, rice straw,
and seaweed, at relatively low temperatures were performed in a fixed bed downdraft …

This paper addresses the solar thermochemical conversion of biomass or waste feedstocks
based on pyro-gasification for the clean production of high-value and energy-intensive fuels …

Iron sand as an industrial by-product has a reasonable iron content (35 wt% Fe) and low
economical cost. The reactivity of iron sand as an oxygen carrier was examined in a …

Alkali and alkaline earth species in biomass have self-catalytic activity on the steam
gasification to produce hydrogen-rich gas. In this study, three types of biomass, ie, brown …
