A proprietary hydrometallurgical process known as Re-2Ox —originally conceived for the production of high-grade cobalt sulfate from mineral resources — is now showing promise in the field of battery recycling. “We did some preliminary test work and the technology was…
Conventional propane dehydrogenation (PDH) is an endothermic, equilibrium-limited reaction that requires high temperatures to achieve commercially viable per-pass yields of propylene. Oxidative propane dehydrogenation has the potential to form propylene at much lower temperatures and more selectively by controlling the…
After a rough past year, petroleum refineries are seeking profit opportunities through the use of renewable feedstocks, such as vegetable oils and waste fats, as well as with new alkylation technologies and by increasing “crude-to-chemicals” (C2C) approaches The past 18…
