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

The minimum fluidization velocity (Umf), bubble size characteristics, and tube-to-bed heat transfer coefficient (hc) of ilmenite particles are investigated at pressures up to 2000 kPa. The Umf was found to decrease with pressure for dsv ≥ 236 μm a

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

Chemical looping reforming is a promising option for the conversion of gaseous fuels to high quality syngas suitable for gas-to-liquids (GtL) processes. This work evaluates the potential for syngas, heat, power, and steam generation for diluent produ

Chemical looping combustion is a promising option for the conversion of fossil fuels with inherent separation of CO2 and efficient use of energy. Nevertheless, key process challenges such as oxygen carrier reaction rates, costs, and environmental con

The co-combustion of a high-sulfur lignite and biomass blend (up to 50% by weight) has been studied in a small oxy-fired circulating fluidized bed combustion (CFBC) pilot plant. Here the goal is to examine the effect of biomass share on NOx, SO2 and

Calcium looping is CO 2 capture technology that is considered to be technically feasible at an industrial scale using a variety of fuels such as natural gas, coals, biomass, refuse derived fuels, and biofuels. Unfortunately, many of these fuels conta

Fluidized bed combustors generally exhibit good mixing characteristics, but there can be localized regions where there is insufficient oxygen to fully combust the fuel. Through incorporation of an oxygen carrier into a high pressure, pulverized fuel

The Canadian regulations on carbon dioxide emissions from power plants aim to lower the emissions from coal‐fired units down to those of natural gas combined cycle (NGCC) units. Since coal is significantly more carbon intensive than natural gas, co

In this paper, a naturally occurring ilmenite ore and the same ore modified with NiO were employed as oxygen carriers for chemical looping reforming of CH4 for syngas production. The reactivity of the oxygen carriers and the syngas selectivity with C
