As a new branch of MOFs which are composed of biocompatible metal ions and organic ligands, bio-metal-organic frameworks (bio-MOFs) have attracted much attention recently. Bio-MOFs feature multiple Lewis basic sites which have strong interaction with CO2 molecules, thus they have great potential in the separation and purification of gas mixtures containing CO2. In this work, molecular simulatio...

Transitioning to energy-saving and renewable energy sources is impossible without accelerated development of hydrogen technologies. This review summarizes the state-of-the-art recent advances various production processes, including but not limited thermochemical electrolytic processes. Their opportunities limitations, operating conditions, catalysts are discussed. Nowadays, most still produced ...

The genome of Halobacterium sp. strain NRC-1 contains a large gene cluster, gvpMLKJIHGFEDACNO, that is both necessary and sufficient for the production of buoyant gas-filled vesicles. Due to the resistance of gas vesicles to solubilization, only the major gas vesicle protein GvpA and a single minor protein, GvpC, were previously detected. Here, we used immunoblotting analysis to probe for the p...

The article proposes the improvement of adsorption and absorption plants for recovery naphtha vapors through use a sulfur compounds purification unit. This unit allows you to remove environmentally hazardous components from vapors, which adversely affect filters, without increasing temperature significant pressure drop gas-air mixture. relevance study is due fact that marine terminals are objec...

An in depth analysis of gold nanoparticle (AuNP) synthesis and size tuning, utilizing carbon monoxide (CO) gas as a reducing agent, is presented for the first time. The sizes of the AuNPs are tunable from ~4 to 100 nm by altering the concentration of HAuCl4 and inlet CO gas-injection flow rate. It is also found that speciation of aqueous HAuCl4, prior to reduction, influences the size, morpholo...

Electrochemistry on gases originated in 1839 with Grove's "gaseous voltaic battery". Over 90 years later, Bacon built a demonstration fuel cell consisting of porous nickel electrodes. He is credited with creating a stable three phase reaction zone of electrode, gas, and electrolyte. Today's fuel cell electrodes are far more sophisticated and lend themselves to other important electrochemical pr...

We develop a novel superstructure of algal biorefinery processes for biological carbon sequestration and utilization, encompassing off-gas purification, algae cultivation, harvesting and dewatering, lipid extraction, remnant treatment, biogas utilization, and algal oil upgrading stages. Based on the superstructure, we propose a mixed-integer nonlinear programming (MINLP) model to minimize the u...

In this study, hydrogen production performances of groundnut shells in a circulating fluidized bed gasifier is evaluated by employing previously developed and validated model. Basically, we simulate gasification system that connected to water-gas shift reactor, for purification with the temperature 1150 K. We find amount gas produced from increases 49.25 kmol 68.83 (per 1000 kg raw shells) when...
