What does this research mean for the field?

Substituting natural gas with captured CO2 in Fischer-Tropsch diesel production significantly reduces direct process emissions but increases indirect emissions due to higher energy demands, with combined heat and power (CHP) integration achieving the lowest overall emissions.

This research aims to quantitatively analyze the GHG emission characteristics of Fischer-Tropsch fuel production processes using different feedstocks.
Utilized Aspen Plus for process simulations to evaluate a natural gas-based FT process as reference.
Developed four scenarios including captured CO2 utilization and CHP integration.
Adopted a gate-to-gate system boundary to focus on emissions during fuel production.
Feedstock substitution reduced direct process emissions (Scope 1) to 5% and 1% in respective scenarios.
The CHP-integrated scenario achieved the lowest overall emissions by minimizing external energy dependence.
The fully integrated scenario increased emissions due to higher complexity and energy needs.
