Biogas — produced from anaerobic digestion of organic matter — contains a mixture of gases, with methane and carbon dioxide as the predominant components. To use biogas as a fuel source, purification of the gas is typically needed to remove…
Chemical processors are harnessing the powerful fusion of advanced analytics and increasing artificial intelligence capabilities to optimize processes and enhance operational productivity As analytical technology matures throughout the process industries, a new generation of chemical process industries (CPI) engineers are…
As industries and consumers have shown an increasing preference for water and oil repellents that do not include any fluorinated materials, significant efforts and years of research and testing have gone into developing non-fluorinated alternatives. AGC Chemicals Americas, Inc. (AGCCA;…
Safe and cost-effective storage represents one of the major hurdles in the widespread adoption of “clean” hydrogen in energy applications. A hydrogen-storage approach called cryo-compression is being poised as a bridge between high-density (but expensive) hydrogen liquefaction and cheaper (but…
Recycling vehicle tires is complicated because the rubbers used (including butadiene and polyisoprene) are highly cross-linked, and because pyrolysis-based recycling of the rubbers generates environmentally hazardous compounds like benzene and dioxins. Now, researchers at the University of North Carolina at…
The past several years have seen rapid growth in technologies designed to mitigate the effects of climate change. Advances have been made in decarbonization efforts, such as alternatives to petroleum-based fuel sources including biofuels, hydrogen, solar, wind and other renewables;…
The ability to economically produce large scales of graphene will help to enable many high-performance applications, from smart packaging materials and medical devices to safer gas storage. A new process demonstrated at Southwest Research Institute (SwRI; San Antonio, Tex.; www.swri.org)…
Researchers from the Lawrence Berkeley National Laboratory (Berkeley, Calif. www.lbl.gov), along with a host of collaborators, have made progress on an artificial photosynthesis system that converts CO2 into ethane and ethylene using nanostructured copper and perovskite. In a recent publication…
Industrial fermentation using bacteria, yeast and other microbes to produce specific products has the potential to reduce future dependence on fossil-fuel-derived chemicals. To further the economic viability of industrial fermentation processes, engineers have turned to genetic modification to stimulate production…
In adsorption processes using steam to regenerate activated carbon, the carbon’s physical characteristics can greatly impact efficiency and optimization Processes using activated carbon as an adsorbent (Figure 1) can be ideal candidates for regeneration using hot fluids like CO2, CH4,…
