“…25 The GtL process provides an effective mechanism in increasing the supply of domestic transportation fuels by reducing dependence on oil imports, thus enhancing energy security. 6 Studies have shown that the GtL process exhibits carbon conversion efficiency (i.e., carbon in the feedstock that is converted to fuels) as high as 52%, 26 which is significantly higher than those from CtL (28%-34% 27 ) and BtL (43% 28 ), as shown in Table 1. In addition to high carbon efficiency from GtL, significant drivers for the development of the GtL technology could be attributed to the following factors: 29 • The GtL process has high exothermicity, where the excess heat generated could be configured to produce electricity and steam.…”

With the increased availability of low-cost natural gas, the co-conversion of natural gas and biomass-to-liquid fuels has attracted attention from industry due to its potential for improving liquid fuel yields while lowering greenhouse gas emissions. This study provides an understanding of Fischer-Tropsch kinetics, improvements in processing strategies for hydrocarbon production, and of its impact on cost for the co-conversion of natural gas and biomass-to-transportation fuels. Studies that investigate the effect of Fischer-Tropsch reaction kinetics on techno-economic analysis can be used to develop process models that consider reaction stoichiometry and account for the effect of the paraffin-to-olefin ratio. We consider two processing scenarios: (1) one that does not employ a hydrocracker, and (2) the other where a hydrocracker serves as an integral part of the process scheme. Our analysis shows that co-processing natural gas not only facilitates the economic benefits of converting biomass-to-liquid fuels but also facilitates flexibility in process integration. The resulting minimum fuel selling price ranged from $2.47-$3.47/GGE (gallon gasoline equivalent) without the hydrocracker and ranged from $2.17-$3.60/ GGE with the inclusion of the hydrocracker, for a 50 million GGE hydrocarbon fuel production facility and for varying blending ratios for biomass from 0-100% with natural gas. The hydrocracker helps to increase the production of diesel and jet fuels substantially, with carbon efficiencies of 50% attained for a chain growth probability of 0.87. The cost penalty comes from the capital expenses of the hydrocracker, and the

The Fischer–Tropsch (FT) process is an alternative route to produce petroleum crude equivalent, as this process converts carbonaceous feedstock‐derived (e.g. coal, biomass, natural gas) syngas to synthetic liquid fuels and chemicals. The technology also is known as gas‐to‐liquid (GTL), coal‐to‐liquid (CTL) and biomass‐to‐liquid (BTL) depending on the source of the syngas. Global demand for clean transportation fuels, volatile oil prices, unstable market scenarios and dwindling reserves of petroleum crude are the major drivers for fostering the FT process. FT‐derived synthetic liquid fuel has enormous potential to replace petroleum crude‐based transportation fuels. There is a possibility that individual countries can produce significant shares of their fuel using CTL, GTL and BTL technologies which help during shortages/peak oil circumstances. The present article summarizes the development of conversion of the different carbonaceous feedstock to liquid fuel including syngas generation, as well as catalytic conversion to liquid fuel via the FT route. © 2020 Society of Chemical Industry
