Syngas production via biomass self-moisture chemical looping gasification

Biomass and Bioenergy, 2017
Abstract Fresh biomass self-moisture gasification (BSMG) is a promising route for biomass utilization. Unlike conventional biomass steam gasification (BSG), BSMG used the moisture content in biomass as the gasifying agent. In this work, the performance of biomass self-moisture chemical looping gasification (BSM-CLG) was compared with dry biomass ...

The behavior of organic sulfur species in fuel during chemical looping gasification

Environmental Pollution, 2022
Uncoupling chemical looping gasification (CLG), the organic sulfur evolution was simulated and explored qualitatively and quantitatively using typical sulfur compounds on TG-MS and temperature-programmed fixed bed. The HS radical in the reductive atmosphere easier converted to H2S and COS.

Investigation of Gasification Chemical Looping Combustion Combined Cycle Performance

Energy & Fuels, 2008
A novel combined cycle based on coal gasification and chemical looping combustion (CLC) offers a possibility of both high net power efficiency and separation of the greenhouse gas CO2. After pressurization, a coal slurry enters a pipe-type gasifier immersed in the CLC air reactor and takes in the heat released from the air reactor.

Gasification inhibition in chemical-looping combustion with solid fuels

Combustion and Flame, 2011
Chemical-looping combustion (CLC) is a novel technology that can be used to meet growing demands on energy production without CO2 emissions. The CLC process includes two reactors, an air and a fuel reactor. Between these two reactors oxygen is transported by an oxygen carrier, which most often is a metal oxide.

Thermodynamic analysis of chemical looping gasification coupled with lignite pyrolysis

Energy, 2019
Abstract A poly-generation system integrating coal pyrolysis and chemical looping gasification (CLG) is proposed to realize the multi-generation of value-added chemicals, synthetic gas fuels and heat/electricity. In this system, the models including coal pyrolysis, coal drying, air reactor (AR) and fuel reactor (FR) are employed to simulate the ...

Experimental Investigation in Autothermal Chemical Looping Gasification

In light of the current climate change efforts to reduce the emission of greenhous gases (GHGs) to the atmosphere are required. The sustainable utilization of biomass as carbon carrier and energy carrier opens up the possibility of carbon neutral or even carbon negative technologies.
