Thermodynamic equilibrium analysis of H2-rich syngas production via sorption-enhanced chemical looping biomass gasification

H 2 -rich syngas production by sorption enhanced steam gasification of palm empty fruit bunch

“…This increases the concentration of H 2 in the syngas. The optimal temperature based on literature studies is 500-750 °C under atmospheric pressure [21][22][23][24][25]. This is related to CO 2 absorption so that syngas rich in H 2 and low in CO 2 concentration is obtained.…”

Thermodynamic assessment and techno-economic analysis of a liquid indium-based chemical looping system for biomass gasification

“…It can be employed for gasification of high-grade feedstock such as natural gas, or low-grade feedstock, such as pyrolysis oil, biomass, municipal waste and coal. As an example, Chein et al [13] carried out thermodynamic modelling showing that gasification of biomass feedstock, such as Miscanthus or peach stone, can be achieved at 500 to 750 °C using CLG systems. However, the performance of the process was limited by the reactivity of CaO, which is reduced by increasing the temperature of the gasification reactor [13] .…”

A thermo-gravimetric analysis was conducted by Yan et al [14] to investigate the chemical looping gasification process for corn straw using iron-based oxygen carrier.…”

CaO-Assisted Alkaline Liquid Waste Drives Corn Stalk Chemical Looping Gasification for Hydrogen Production

“…In a fuel reactor (FR), OC plays multiple roles, including catalyzing tar and hydrocarbon reforming and oxidizing biomass and volatile compounds into CO, CO 2 , CH 4 , and H 2 O. 5 , 6 Syngas can be used to synthesize hydrocarbons under the Fischer–Tropsch process. Then, the reduced OC is transferred into the air reactor (AR), where it is oxidized by air for the next CLG cycle.…”

“…CLG utilizes an oxygen carrier (OC) (e.g., the metal oxides of Cu, Ni, Fe, Mn) rather than O 2 to transfer oxygen to partially oxidize biomass into syngas. − As shown in Figure , a CLG system consists of two interconnected reactors. In a fuel reactor (FR), OC plays multiple roles, including catalyzing tar and hydrocarbon reforming and oxidizing biomass and volatile compounds into CO, CO 2 , CH 4 , and H 2 O. , Syngas can be used to synthesize hydrocarbons under the Fischer–Tropsch process.
