Methanol production using carbon capture technology: An overview / Mohd Aizad Ahmad and Zulkifli Abdul Rashid

Carbon emission to environment cause global warming problems. Research on carbon capture
technology has been widely established including pre-combustion, post-combustion and oxyfuel
method. Utilisation of carbon from capture process has been developed for methanol production.
Various separation method of CO2 from gas has been highlighted. Challenges and potentials of
methanol production using carbon capture utilisation (CCU) should be taken into account. The
major challenge for methanol production from carbon capture is to produce catalysts which are
selective, lower cost and long term recyclable which will allow the reduction of carbon dioxide to
methanol. Researchers also discussed how to produce minimum cost of sustainable hydrogen
supply to react with CO2. For oxyfuel combustion technology, the challenges are the capital cost
and energy consumption mostly from cryogenic air separation unit (ASU). An overview of
methanol production using various method of carbon capture has been discussed in this paper.
