Carbon Efficiency Targets for Methanol Production from a Hybrid Solar -Carbonaceous Feedstocks Process

摘要

The carbon efficiency of a methanol production process that utilises concentrated solar power has been determined using basic process synthesis tools. The relationship between the hydrogen and oxygen content of the carbonaceous feed material and the carbon efficiency as well as the energy requirements has been explored. The target carbon efficiency of gasification-based methanol production from carbonaceous materials can be increased by 10-20% by employing concentrated solar power (CSP) depending on the hydrogen and oxygen content of the feed material. Further improvement in carbon efficiency can be attained by considering process that may not be gasification-based, but rather employ a novel overall mass balance.
