Effect of Biomass Char Additives on the Hydrogasification Behavior of a Bituminous Coal
BioResources, 2016 The hydrogasification behavior of a Chinese bituminous coal with three different biomass char additives, i.e., sargassum char (SG char), saw dust char (SD char), and wheat straw char (WS char), was studied in a pressurized fixed bed reactor.

Simultaneous removal of SO2 and NOx with ammonia combined with gas-phase oxidation of NO using ozone [PDF]
Chemical Industry and Chemical Engineering Quarterly, 2015 A process for simultaneous desulfurization and denitrification was proposed, which was made up of ozone as the oxidizing agent for NO and ammonia solution as absorbent. The results showed that the presence of SO2 and the concentration changes of

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
