Integrated and closed‐loop biorefinery strategies for efficient waste valorization and biofuel production

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Advancements in biofuel production technologies are essential for reducing global dependence on fossil fuels and addressing their overexploitation. Many valuable components of biomass, such as cellulose, hemicellulose, and lignin, remain underused in traditional biorefineries, which typically rely on a single feedstock to produce a primary ...

Chemical-looping combustion characteristics of Zhundong coal semicoke with hematite oxygen carrier and transformation of alkali and alkaline earth metals

Meitan xuebao
The low-carbon, clean, and efficient utilization of the Zhundong coal is greatly limited by some severe problems such as ash accumulation, slagging, and CO2 emissions in the conventional combustion and utilization processes. The adoption of low-rank coal

Process Control Strategies in Chemical Looping Gasification—A Novel Process for the Production of Biofuels Allowing for Net Negative CO₂ Emissions

Applied Sciences, 2020
Chemical looping gasification (CLG) is a novel gasification technique, allowing for the production of a nitrogen-free high calorific synthesis gas from solid hydrocarbon feedstocks, without requiring a costly air separation unit.

Economic assessment of chemical looping oxygen production and chemical looping combustion in integrated gasification combined cycles

International Journal of Greenhouse Gas Control, 2018
Abstract Chemical looping promises significant reductions in the cost of CO2 capture and storage (CCS) by enabling energy conversion with inherent separation of CO2 at almost no energy penalty. This study evaluates the economic performance of a novel power plant configuration based on the principle of packed bed chemical looping.

Mechanism study on the high-performance BaFe2O4 during chemical looping gasification

Fuel, 2022
Abstract As an attractive oxygen carrier, BaFe2O4 shows an outstanding chemical looping gasification (CLG) performance with a high CO yield, but the reaction mechanisms of BaFe2O4 during CLG process are still not clear. The present work aims to reveal the reaction mechanisms of BaFe2O4 with solid carbon (C) and carbon monoxide (CO) by means of ...

Sulfur Tolerance of CaxMn1–yMyO3−δ (M = Mg, Ti) Perovskite-Type Oxygen Carriers in Chemical-Looping with Oxygen Uncoupling (CLOU) [PDF]

, 2014
Perovskite-structured oxygen carriers of the type CaxMn1–yMyO3−δ (M = Mg, Ti) have been investigated for the CLOU process. The oxygen carrier particles were produced by spray-drying and were calcined at 1300 °C for 4 h.

A study of Ni‐Co/CeO2 catalyst derived from metal–organic framework for dry reforming of methane

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The efficacy of cobalt‐doped, MOF‐derived catalysts for dry reforming of methane (DRM) was examined. The focus was on the influence of varying nickel and cobalt molar ratios on catalytic performance. Three catalysts with Ni:Co ratios of 1:1, 1:0.5, and 0.5:1, were synthesized and tested with cerium oxide as a constant support. The DRM reaction

Bottlenecks‐Breaking in Zinc‐Iodine Batteries Toward Practical Implementation: A Review and Perspective

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Aqueous zinc–iodine batteries (Zn–I2Bs) offer promise for grid storage due to safety and cost advantages yet face critical bottlenecks: severe self‐discharge (polyiodide shuttling and HER), limited energy density, sluggish kinetics, and zinc anode instability.
