The concentration of residual O2 in oxy-fuel combustion flue gas needs to be reduced before CO2 transportation, utilization, or storage. An original application of the printed circuit heat exchanger (PCHE) for catalytic combustion with natural gas (c

The replacement of the blast furnace—basic oxygen furnace (BF-BOF) steelmaking route with the direct reduced iron—electric arc furnace (DRI-EAF) route reduces the direct CO2 emissions from steelmaking by up to 68%; however, the DRI shaft furnace

To achieve net-zero emissions by the year 2050, carbon capture, utilization, and storage technologies must be implemented to decarbonize sectors with hard-to-abate emissions. Pressurized chemical looping (PCL) with a novel reactor design called a plu

Abstract We explore the driving of LEDs by untransformed AC. An extreme case is driving 1.9 V threshold (red) LEDs with UK mains, peak voltage 325 V. Commonly, driving is by transformed, rectified (DC) supply with a series resistor (where a significa

The goal of this work was to investigate the impact of pressure and the presence of fine particles (i.e., a surrogate for pulverized fuel) on the overall surface-to-bed heat transfer coefficient in relation to an oxygen-fired pressurized fluidized be

Thermal cracking involves the breakdown of large hydrocarbons to smaller hydrocarbons via the scission of carbon–carbon, carbon–nitrogen, and carbon–sulfur bonds. Mild thermal cracking reactions occur between 350 and 450 °C and primarily in th

Pressurized Chemical Looping Combustion (PCLC) is a promising technology for mitigating CO2 emission from fossil fuel combustion. This work investigates the oxidation kinetics of a natural ilmenite ore to assess the PCLC of natural gas since process
