“…However, Zhong et al and Li et al reported in recent research the activity of the Co 2 C nanoprism, which is selective toward smaller olefins (C 2 –C 4 ). Other inactive species identified in Co-based catalysts include CoAl 2 O 4 and Co 2 O 4 Si, which are formed due to strong metal–support interactions (MSI) and may be present when using conventional supports, such as Al 2 O 3 and SiO 2 , respectively. , Although catalyst deactivation may vary according to the process, mechanism, and catalyst design, Co-based catalysts have generally been reported to experience a slower deactivation process compared to Fe-based materials, promoting higher lifetimes for Co-based catalysts ,, due to the lower reoxidation and coke deposition rates of Co-based catalysts compared with Fe-based catalysts. , …”

Fischer–Tropsch (FT) synthesis is an important reaction for the alternative production of high-quality liquid fuels, which promote sustainable development by enabling economical decarbonization. The one-stage FT process involves both hydrocarbon growth and hydrocracking/isomerization in a single step and is more energy and cost efficient than the two-stage process. Bifunctional catalysts, composed of acid and metal sites, are needed in order to achieve one-step synthesis. In this review, we discuss the state of the art concerning the use of bifunctional catalysts for the one-stage FT process, focusing on the effect of metal and acid sites on the catalytic performance. Several supports with potential utility for the one-stage FT process were analyzed, including zeolites, clays, alumina, silica, aluminosilicates, and carbons, and the advantages and disadvantages of each are evaluated.

“…To optimize the process both thermodynamically and kinetically, industrial WGS reaction application are conducted in multiple adiabatic stages consisting of a high temperature shift (HTS) followed by a low temperature shift (LTS) with intersystem cooling. Thus two equilibrium reactors may be desired; the first being HTS to ensure the complete conversion of carbon monoxide and about 3% carbon monoxide exit composition and a later LTS equilibrium reactor is needed to produce carbon monoxide exit composition of less than 1% thus increasing hydrogen production [12].…”

Gas-to-Liquids (GTL) technologies have the potential to convert associated flare gases into premium transport liquids, creating a market for the otherwise stranded resource. However, the capital cost of GTL plants has over the years hampered the choice of the project. The drive for GTL is improved by optimization of the plant such that its efficiency and profitability is increased. One such notable improvement in GTL plant configuration is the integration of power production unit in the GTL process plant such that GTL liquids production and electricity production can occur concurrently in the same plant. This method generally called GTL-power co-production will increase the overall efficiency and profitability of existing GTL plant process and present ways to economically optimize the heat loss through the by-product streams (steam and flue gas streams). The utilization of the by-product streams will account for reductions in thermal inefficiencies within the GTL plant process. In this work, additional unit is added to the 863.3 m3 /d GTL product plant configuration to utilize the by-product steam stream for electricity generation. This additional electricity unit generated 10 MW of electricity increasing the net present value (NPV) of the plant by 4.72% while the net cash recovery (NCR) increased by 3.87%. Furthermore the pay-out time reduced by 2%. The GTL-Electricity co-production has proven to be a means of optimizing GTL plant, having capability to yield more profits due to reduced capital and operational expenses than if the plants were operated separately.

“…162,163 Sasol also made several major modifications in reactor design and developed an advanced fluidized bed reactor for using fused Fe catalyst for CTL synthesis. 164 The Mossgas plant started in South Africa in 1992 to produce FT products from natural gas using Fe-based catalyst sat higher temperature. Thereafter, in 1993, a FT synthesis plant based on natural gas with a capacity of 12 500 bpd was placed into operation in Bintulu, Malaysia.…”

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
