چکیده
Abstract 5 The techno-economic potential of the UK poplar wood and imported oil palm empty fruit 6 bunch derived bio-oil integrated gasification and Fischer-Tropsch (BOIG-FT) systems for the 7 generation of transportation fuels and combined heat and power (CHP) was investigated. The 8 bio-oil was represented in terms of main chemical constituents, i.e. acetic acid, acetol and 9 guaiacol. The compositional model of bio-oil was validated based on its performance through a 10 gasification process. Given the availability of large scale gasification and FT technologies and 11 logistic constraints in transporting biomass in large quantities, distributed bio-oil generations 12 using biomass pyrolysis and centralised bio-oil processing in BOIG-FT system are technically 13 more feasible. Heat integration heuristics and composite curve analysis were employed for once14 through and full conversion configurations, and for a range of economies of scale, 1 MW, 675 15 MW and 1350 MW LHV of bio-oil. The economic competitiveness increases with increasing 16 scale. A cost of production of FT liquids of 78.7 Euro/MWh was obtained based on 80.12 17 Euro/MWh of electricity, 75 Euro/t of bio-oil and 116.3 million Euro/y of annualised capital cost. 18

Development of an Integrated Structure of CHP and Heavy Hydrocarbons Liquids Using Fischer-Tropsch Synthesis
Recent developments in gas-to-liquid conversion industry lead to reduction in initial investment, and it is expected by growth in demand for refined products in countries and the need to import these products in the countries. Implementing such projects can prevent currency outflow. In this article an integrated structure is developed for producing liquid fuels from natural gas through Fischer-...

Nano-sized iron-based catalyst was prepared by the micro-emulsion method. The composition of the final nano-sized iron catalyst, in term of the atomic ratio contains: 100Fe/4Cu/2Ce. Experimental techniques of XRD, BET, TEM and TPR were used to study the phase, structure and morphology of the catalyst. Fischer-Tropsch Synthesis (FTS) reaction test was performed in a fixed bed reactor at pressure...

In this research, the performance and kinetics of an iron/manganese oxide catalyst in a fixed-bed reactor by Fischer-Tropsch Synthesis is studied. The range of operating conditions are; P = 1 – 12 bar, T = 513 - 553 K, H2/CO ratio = 1 - 2 and GHSV = 4200 – 7000 ((〖cm〗^3 (STP))/h/g_cat). The effect of these independent variables, on Fischer-Tropsch product were performed by using a statistical m...

متن کاملA review of Fischer-Tropsch synthesis on the cobalt based catalysts
Fischer-Tropsch synthesis is a promising route for production of light olefins via CO hydrogenation over transition metals. Co is one of the most active metals for Fischer-Tropsch synthesis. Some different variables such as preparation parameters and operational factors can strongly affect the selectivity of Fischer-Tropsch synthesis toward the special products. In the case of preparat...
