Innovative Approach to Hydrogen Purification: A Review on the Role of Metal Hydrides

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Metal hydrides, renowned for their unique hydrogen bonding capabilities, have emerged as pivotal materials in the energy sector, particularly for hydrogen storage and purification applications. Their ability to store hydrogen reversibly under moderate conditions has positioned them at the forefront in hydrogen‐based energy systems. This review

Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Life Cycle Assessment of Sweet Sorghum as Feedstock for Second-generation Biofuel Production [PDF]

, 2017
There exist few life cycle assessments (LCAs) in the literature that focus on the second-generation biofuel production from sweet sorghum, a non-food-source feedstock that offers several advantages in terms of farming requirements compared to corn or ...

Metabolic engineering of Moorella thermoacetica for thermophilic bioconversion of gaseous substrates to a volatile chemical

AMB Express, 2021
Gas fermentation is one of the promising bioprocesses to convert CO2 or syngas to important chemicals. Thermophilic gas fermentation of volatile chemicals has the potential for the development of consolidated bioprocesses that can simultaneously separate

Biological conversion of carbon monoxide to ethanol: Effect of pH, gas pressure, reducing agent and yeast extract [PDF]

, 2012
A two-level full factorial design was carried out in order to investigate the effect of four factors on the bioconversion of carbon monoxide to ethanol and acetic acid by Clostridium autoethanogenum: initial pH (4.75–5.75), initial total pressure (0.8–1 ...

Volumetric mass transfer and dilution rate as key parameters for sustainable industrial syngas fermentation to isopropyl alcohol: modeling and parametric assessment

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Synthesis gas fermentation is a promising route for the valorization of steel mill off‐gas and for replacing conventional fossil‐based isopropyl alcohol (IPA) production. A recent 120 L pilot‐scale study reported 85% gas conversion at 90% product selectivity and claimed a negative global warming potential (GWP) without detailed process design.

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 ...

Parametric study on the heating values of products as via steam gasification of palm waste using CaO as sorbent material [PDF]

, 2016
In Malaysia, due to abundance of oil palm waste, it is a good candidate to be used as a feedstock for syngas and hydrogen production. Biomass steam gasification is one of the promising methods for syngas production.
