Green Methanol Production Process from Indirect CO2 Conversion: RWGS Reactor versus RWGS Membrane Reactor

The Potential for Electrons to Molecules Using Solar Energy

“…M. Liu et al 2020). Typically, the H2 to CO2 ratios required to promote the RWGS reaction or to produce a specific syngas composition range from 1 to 4 (Pastor-Pérez et al 2017;Samimi, Hamedi, and Rahimpour 2019;Dzuryk and Rezaei 2020;Knighton et al 2020;C. M. Liu et al 2020).…”

“…In addition to considering advancements in RWGS catalyst performance, recent research has focused on intensifying the RWGS process because of its low equilibrium constant and poorer CO2 conversions at high space velocities. Packed bed membrane reactors have been investigated as the removal of produced water shifts the equilibrium to the right and removes the need for downstream water separation units (Samimi, Hamedi, and Rahimpour 2019;Dzuryk and Rezaei 2020). Also, NASA has investigated Precision Combustion Inc's RWGS reactor prototype based on patented Microlith technology to address issues such as reactor size and heat transfer associated with conventional RWGS reactors (Vilekar et al 2012;Abney et al 2016).…”

Electrocatalysts for direct methanol fuel cells to demonstrate China's renewable energy renewable portfolio standards within the framework of the 13th five-year plan

“…is unfavored, thereby requiring higher temperatures to drive it, which also promotes the reverse water gas shift relative to hydrogenation of CO 2 to methanol. The current approach focuses on liquid phase methanol synthesis rather than gas-phase methanol hydrogenation [ 116 ]. The major metal catalyst for methanol synthesis is based on copper, zinc oxide, and alumina [ 117 ].…”

Improved the Methanol Electro-Oxidation and Carbon Monoxide Tolerance for Direct Methanol Fuel Cells Using Strontium Molybdate

“…The European Union's energy and climate policy requires energy system transformations to reduce greenhouse gas emissions in 2050 to less than 80% of 1990 levels [1]. The conversion of carbon dioxide produced by feedstock into green methanol [2] is a key strategic factor for renewable energy and creating a low-carbon economy. The manufacturing cost of renewable methanol will be gradually reduced by 2030, making it cheaper than coal and natural gas [2].…”
