Roles of Activated Carbon and Tetrahydrofuran on Methane Hydrate Phase Equilibrium

Chemical Engineering Transactions, 2014
This work studied the effects of activated carbon and tetrathydrofuran (5.56 mol % THF) on methane hydrate phase equilibrium and hydrate dissociation. The hydrate formation was carried out in the quiescent condition and close system at 4 °C.

Chlorella vulgaris biorefineries: sustainable biofuels and high‐value carbon capture

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Global reliance on fossil fuels has created urgent economic and environmental challenges, yet large‐scale use of algal biomass remains limited by production costs. Industrial scaling is constrained by inefficient harvesting and the technical challenges of processing recalcitrant cell walls.

Comparative field‐scale assessment of TLUD and Kon‐Tiki biochar systems: agronomic performance and net CO2e‐based techno‐economics

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Post‐harvest agricultural residues in Latin America are commonly underutilized, leading to greenhouse gas emissions and lost opportunities for bio‐based value creation. This study tests the hypothesis that decentralized, farmer‐scale pyrolysis technologies can deliver comparable agronomic benefits while exhibiting distinct techno‐economic and ...

Comparative Study of Methane Hydrate Formation and Dissociation with Hollow Silica and Activated Carbon

Chemical Engineering Transactions, 2018
Natural gas hydrates are ice-like crystalline compounds and non-stoichiometric, and methane is trapped inside the water cages of the hydrates. In recent years, the hydrates have received much attention for natural gas storage and transportation. However,

Emerging research directions in nanoparticle‐based foam control for bioprocessing: a bibliometric approach

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Overfoaming remains a critical challenge in industrial bioprocesses, compromising mass transfer, operational stability, and downstream efficiency in bioreactors and wastewater treatment systems. This study provides a bibliometric and scientometric assessment of nanoparticle‐enabled foam control to map technological trends and identify research

The effect of hydrate content on seismic attenuation: A case study for Mallik 2L-38 well data, Mackenzie delta, Canada

, 2004
Observations of velocities in sediments containing gashydrates show that the strength of sediments increases with hydrate saturation. Hence it is expected that the attenuation of these sediments will decrease with increasing hydrate saturation.

Porous Carbon Materials for Carbon Dioxide Capture

Carbon Energy, EarlyView.
This work aims to address the current status and challenges associated with the regulation of pore structures, as well as the influence of pore structures on CO2 capture. Systematic quantitative analysis of structure–property relationships, combined with machine learning approaches, can effectively evaluate the contributions of structural ...
