“…When the syngas is produced from coal, iron-based materials are used industrially to catalyse this process, [1][2][3][4][5][6] where structural and chemical promoters, such as silica, potassium, sodium, copper, calcium, zinc, zirconium and chromium, 5,[7][8][9] are added to improve the catalyst selectivity, activity and stability toward sintering. Mn is widely used as the promoter of choice for iron FTS catalysts, particularly when used for producing lower olefins.…”

“…Dry reported the H2/CO ratio (by moles) into slurry reactor for iron catalyst was 1.7 [34]. But in other studies, the H2/CO ratio seemed in favor of 0.67 [35,36]. And then, a series of iron based catalysts were improved and ran at the mole ratio from 1.0 to 1.7 in the pilot plant test.…”

Abstract-Integrated systems of FT liquids processes and waste energy utilization based on Shell, GSP and GE gasification are designed and simulated. The results show that under the condition of 1 000 t/hr coal feedstock, the yields of the liquids, including diesel, naphtha and LPG, are 205.2t/hr, 73.2t/hr and 40.1t/hr, respectively based on shell; 205.1t/hr, 73.2t/hr and 40.1t/hr, respectively based on GSP; 183.8t/hr, 65.6t/hr and 35.9t/hr respectively based on GE. However, the electricity generation equivalent to about 2% of coal thermal value cannot meet the power needs of the three systems. Based on LHV, the highest system thermal efficiency of 47.7% comes from the system based on Shell. The lowest system thermal efficiency, resulting from the system based on GE, has decreased 7.1% compared with that of the system based Shell. The proportion of carbon capture to the total carbon entering the systems is 58.7% (for the system based on Shell), 58.6% (for the system based on GSP) and 59.5% (for the system based on GE), respectively.

“…It is known that Fe based catalyst has several advantages in comparison with Co based catalyst. Fe based catalyst is cheaper than Co based catalyst, and it is less sensitive to impurities in synthesis gas [13][14][15]. Consequently, the choice of catalysts should be dependent on the economics of the GTL process, the selectivity of product distributions and the operating conditions of the process.…”

Abstract. GTL (Gas-to-liquid) process is becoming an attractive technology which can produce liquid petroleum products using natural gas. As a part of preliminary design of GTL-FPSO application, process simulation analysis for conceptual design and optimization of reformers and F-T reactors are performed in GTL-FPSO applications by implementing the user made subroutine programs of kinetic equations into PRO/II PROVISION simulator. As for the F-T reactors, Plug Flow Reactor (PFR) model is used with detailed kinetics equations over two different Fe based catalysts (Fe-Cu-K and K/Fe-Cu-Al). Dry reformer is also studied with Plug Flow Reactor (PFR) model. In this study, simulation results are compared with available experimental data and found well agreed with experimental data for both reformer and FT reactor. The Peng-Robinson equation of state is also used to calculate the vapor phase nonidealities and vapor-liquid equilibrium. The optimum operating conditions and process simulation analysis are also presented.
