Clean Hydrogen Production from Low Rank Coal: Novel Integration of Drying, Gasification, Chemical Looping, and Hydrogenation

Chemical Engineering Transactions, 2015
State-of-the-art integrated processes for hydrogen production from low rank coal (LRC) consisting of drying, gasification, chemical looping, and hydrogenation is proposed based on enhanced process integration (EPI).

Enhancement of char gasification in CO2 during chemical looping combustion

Chemical Engineering Journal, 2018
Three chars were gasified in CO2 in a fluidised bed of inert sand or Fe2O3 as an oxygen carrier (either derived from an ore or prepared in the laboratory). Rates of gasification were found to increase with temperature and the presence of active oxygen carriers. The observed change varied both with the chars’ and carriers’ reactivity.

Evaluation of ilmenite, manganese ore, LD slag and iron sand oxygen carriers for chemical looping gasification with microalgae

Fuel Processing Technology
Microalgae could be a sustainable feedstock for production of liquid biofuels. However, as such fuels contain significant fractions of reactive ash species, it is necessary to deploy synthesis routes which can handle such “dirty” fuels.

Investigation of Chemical-looping Gasification Characteristics of Chinese Western Coals with Hematite-CuO Oxygen Carrier [PDF]

E3S Web of Conferences, 2020
In order to realize highly efficient conversion of Chinese western bituminous coals into syngas, a series of chemical-looping gasification experiments was conducted with hematite-CuO oxygen carrier in a laboratory-scale fluidized-bed reactor. The results
