Gasification of coal-derived chars in synthesis gas mixtures under intraparticle mass-transfer-controlled conditions [PDF]

, 1986
A model has been formulated to describe the quasi-steady-state gasification of coal-derived chars in gas mixtures where both the reactants carbon dioxide and steam, and the gasification products carbon monoxide and hydrogen are present.

Improving the Yield and Quality of Tar during Co-pyrolysis of Coal and Cotton Stalk

BioResources, 2015
Co-pyrolysis of Shenmu coal (SM) and cotton stalk (CS) at different blend ratios were carried out in a tubular furnace. The pyrolysis temperature was up to 600 °C at 5 °C/min and kept for 15 min. The results indicated that there was an interactive effect
