Abstract

Ethanol-to-ethylene conversion via catalytic dehydration is optimized using the CircleStar catalyst, whose unique geometry improves heat distribution and site exposure. This enables lower operating temperatures, 99.5% selectivity, and reduced emissions. The process supports renewable feedstocks and yields $70 million in annual profit at scale.
