Abstract

Highlights: Conversion technologies of eGTC and cCTF are considered to an integrated process. Simulation model of the integrated process is developed based on the experiments. Mass and energy integration are performed for the integrated process. Economic feasibility of the integrated process is analyzed. Two process strategies (eGTC-only vs. integrated process) are compared. Abstract: This study presents two biomass conversion strategies: electrocatalytic glycerol-to-chemicals (eGTC) and catalytic corn stover-to-fuels (cCTF). The effect of process integration combining eGTC with cCTF on a commercial scale is investigated to improve energy efficiency and economics of the strategies. In the integrated process strategy, most of the heat requirements for eGTC are supplied by cCTF, and most of the hydrogen requirements for cCTF are provided by eGTC. Process integration leads to higher energy efficiency (27.6%) of integrated process strategy compared to the eGTC-only process (11.4%). The minimum selling price for the integrated process strategy is estimated to $2.35/kgGLA which can be more economically feasible than the eGTC-only process strategy ($2.55/kgGLA ).
