Is the Liquid-Phase H2O2-Based Ethylene Oxide Process More Economical and Greener Than the Gas-Phase O2-Based Silver-Catalyzed Process?

Abstract: An ethylene epoxidation process concept that employs methyltrioxorhenium (MTO) as catalyst and H 2 O 2 as oxidant and selectively produces EO (with no CO 2 as byproduct) has been demonstrated recently by researchers at the University of Kansas Center for Environmentally Beneficial Catalysis (CEBC). On the basis of a plant-scale simulation of the CEBC process using Aspen HYSYS, preliminary economic and environmental assessments of the process are performed, both of which are benchmarked against the conventional… Show more

“…The total project capital cost of the BEP has a mean value of 22 • 10 6 USD, which is in agreement with the economic assessments reported by Cardona et al (2018) and Moncada et al (2014), who reported a total project cost of 73 • 10 6 USD and 56 • 10 6 USD for two biorefineries with 200 t h −1 and 10 t h −1 of feedstock mass flow, respectively. The presented results could have an uncertainty between of 30 and 50% associated with the capital investment calculations due to the complexity of the analysis (Ghanta et al 2013a(Ghanta et al ,2013b, thus they have to be interpreted with caution.…”

“…Recently, we reported a homogenous catalytic process for ethylene epoxidation that uses methyltrioxorhenium (MTO) as catalyst and H 2 O 2 as oxidant providing almost total epoxide selectivity with no CO 2 formation as byproduct [2]. Detailed economic analysis indicates that the use of less expensive and earth-abundant catalytic materials (compared to Re) could improve process economics and practical viability [3]. This motivated us to explore such alternative epoxidation catalyst candidates.…”

“…Recently, we reported a liquid phase ethylene epoxidation process (also referred herein as the CEBC process) that eliminates ethylene burning and produces EO with nearly total selectivity. 1,6,7 Under mild operating conditions of 40°C and 50 bar, the catalyst (methyltrioxorhenium, MTO) shows high activity (1610-4970 mg EO h −1 (g Re)…”
