DESIGN, SIMULATION, AND SUPPLY CHAIN OPTIMIZATION OF HYBRID COAL, BIOMASS, AND NATURAL GAS TO LIQUID (CBGTL) PROCESSES

摘要

The challenges to reduce dependence on petroleum as energy sources, coupled with efforts to reduce greenhouse gas (GHG) emissions, are exigent problems faced by the US transportation sector. Alternative processes that utilize domestically abundant sources and exhibit better environmental performances than petroleum based processes are necessary for sustainable production of transportation fuels. Hybrid energy processes emerge as viable options to address the given challenges due to their capabilities to produce liquid fuels via the thermochemical conversions of multiple energy sources such as coal, biomass, and natural gas. The gasification route involves synthetic gas (syngas) production from coal and biomass gasification or natural gas reforming process. Syngas can subsequently be converted to liquid fuels via Fischer-Tropsch (FT) reactions.
