Toward Carbon–Neutral Methanol: Emerging Technologies, Key Challenges, and the Pathway to Net-Zero Emissions
摘要
The ecologically friendly methanol can be produced using a variety of ways from earth-abundant raw materials and remains simple to handle, store, and logistics, it is regarded as a productive, affordable, and safe substitute for fossil fuels. For reducing carbon emissions in the chemical and energy industries, clean methanol can be a significant contributor to reaching net-zero emission goals. Green methanol is generated from e-methanol, which is made from green hydrogen electrolysis and CO2 collected and biomethanol, which is made by distilling biomass and crop residues. Recent advancements in membrane-based methanol synthesis and purifying technologies are highlighted in the review, covering the use of innovative membrane components such as hybrid framework, ceramics, and polymers. Water can be separated both during and after production using water-selective zeolite membranes. Zeolite membranes within the methanol synthesizing reactor can increase the yield of methanol generation. Furthermore, the present obstacles and potential outcomes for achieving environmentally friendly methanol production on a big scale are examined. In summary, the review highlights topics for further investigation and offers perspectives on the present status of membrane-based techniques for the synthesis and purifying of methanol. The advancement of renewable energies and the enhancement of the technological affordability and productivity depend heavily on the creation of efficient membranes and the optimal configuration of membrane-based activities.
