Single-Pass Demonstration of Integrated Capture and Catalytic Conversion of CO from Simulated Flue Gas to Methanol in a Water-Lean Carbon Capture Solvent.

Here, we demonstrate an integrated semibatch simultaneous CO capture and conversion to methanol process using a water-lean solvent, -(2-ethoxyethyl)-3-morpholinopropan-1-amine (2-EEMPA), that serves as both the capture solvent and subsequent condensed-phase medium for the catalytic hydrogenation of CO. CO is captured from simulated coal-derived flue gas at a target >90 mol % capture efficiency, with a continuous slipstream of CO-rich solvent delivered to a fixed bed catalytic reactor for catalytic hydrogenation. A single-pass conversion rate >60 C-mol % and selectivity >80 C-mol % are observed for methanol at relatively low temperatures (<200 °C) in the condensed phase of the carbon capture solvent.

Integrated Capture and Conversion of CO to Methane Using a Water-lean, Post-Combustion CO Capture Solvent.

Integrated carbon capture and conversion of CO into materials (IC M) is an attractive solution to meet global energy demand, reduce our dependence on fossil fuels, and lower CO emissions. Herein, using a water-lean post-combustion capture solvent, [N-(2-ethoxyethyl)-3-morpholinopropan-1-amine] (2-EEMPA), >90 % conversion of captured CO to hydrocarbons, mostly methane, is achieved in the presence of a heterogenous Ru catalyst under relatively mild reaction conditions (170 °C and <15 bar H pressure). The catalytic performance was better in 2-EEMPA than in aqueous 5 m monoethanol amine (MEA).

Single-step syngas-to-distillates (S2D) process based on biomass-derived syngas--a techno-economic analysis.

This study compared biomass gasification based syngas-to-distillate (S2D) systems using techno-economic analysis (TEA). Three cases, state of technology (SOT), goal, and conventional, were compared in terms of performance and cost. The SOT case represented the best available experimental results for a process starting with syngas using a single-step dual-catalyst reactor for distillate generation.
