Implications of increasing the mol% CO₂ in the feed gas for MeOH synthesis. a) Rate via MeOH synthesis reactions decreasing with more CO₂ in feed. b) Yield of water formed with increasing CO₂ content in the feed, proportionately increases with increasing CO_2. c) Feed %CO_x or CO + CO₂ converted to MeOH with increasing CO₂ in the feed, less with increasing CO₂. d) Percent feed CO₂ conversion (%CO₂) via RWGS (negative indicates WGS occurring) showing that less and less WGS occurs as CO₂ increases favoring RWGS and positive CO₂ conversion
