This study compares the short-term economic feasibility of six conversion pathways for renewable jet fuel (RJF) production. The assessment combines (i) a harmonized techno-economic analysis of conversion pathways expected to be certifi ed for use in commercial aviation by 2020, (ii) a pioneer plant analysis taking into account technological immaturity, and (iii) a quantifi ed assessment of the merits of co-producing RJF alongside existing European supply chains in the pulp, wheat ethanol, and beet sugar industries. None of the pathways assessed are able to reach price parity with petroleum-derived jet fuel in the short term. The pioneer plant analysis suggests that the hydroprocessed esters and fatty acids (HEFA) pathway is currently the best option; the technology achieves the lowest minimum fuel selling price (MFSP) of 29.3 € GJ -1 (1289 € t -1 ) and the technology is deployed on commercial scale already. In the short term, n t h plant analysis shows hydrothermal liquefaction (HTL) and pyrolysis emerging as promising alternatives, yielding MFSPs of 21.4 € GJ -1 (939 € t -1 ) and 30.2 € GJ -1 (1326 € t -1 ), respectively. The pioneer plant analysis shows considerable MFSP increases for producing drop-in fuels using HTL and pyrolysis as both technologies are relatively immature. Hence, further RD&D efforts into these pathways are recommended. Co-production strategies decrease the MFSP by 4-8% compared to greenfi eld production. Integration of process units and material and energy fl ows is expected to lead to further cost reductions. As such, co-production can be a particularly useful strategy to progress emerging technologies to commercial scale.

“…As fuel, it can be blended with gasoline, it can be further transformed and blended with diesel, and it may be used in fuel cells. Recent studies demonstrate an interest on alcohols use as fuel in sectors like maritime [25] and aviation [26]. The production of MeOH is especially attractive in emerging economies, as a liquid fuel to replace conventional sources of energy.…”

Methanol synthesis using captured CO2 as raw material: Techno-economic and environmental assessment

et al. 2016

h i g h l i g h t sA carbon utilisation plant that synthesise methanol is simulated in CHEMCAD. The total amount of CO 2 demand is 1.46 t/t methanol . The CO 2 not-produced compared to a conventional plant is 0.54 t/t methanol . Production costs results too high for a financially attractive project. There is a net potential for CO 2 emissions reduction of 2.71 MtCO 2 /yr in Europe. g r a p h i c a l a b s t r a c t a b s t r a c t The purpose of this paper is to assess via techno-economic and environmental metrics the production of methanol (MeOH) using H 2 and captured CO 2 as raw materials. It evaluates the potential of this type of carbon capture and utilisation (CCU) plant on (i) the net reduction of CO 2 emissions and (ii) the cost of production, in comparison with the conventional synthesis process of MeOH Europe. Process flow modelling is used to estimate the operational performance and the total purchased equipment cost; the flowsheet is implemented in CHEMCAD, and the obtained mass and energy flows are utilised as input to calculate the selected key performance indicators (KPIs). CO 2 -based metrics are used to assess the environmental impact. The evaluated MeOH plant produces 440 ktMeOH/yr, and its configuration is the result of a heat integration process. Its specific capital cost is lower than for conventional plants. However, raw materials prices, i.e. H 2 and captured CO 2 , do not allow such a project to be financially viable. In order to make the CCU plant financially attractive, the price of MeOH should increase in a factor of almost 2, or H 2 costs should decrease almost 2.5 times, or CO 2 should have a value of around 222 €/t, under the assumptions of this work. The MeOH CCU-plant studied can utilise about 21.5% of the CO 2 emissions of a pulverised coal (PC) power plant that produces 550 MW net of electricity. The net CO 2 emissions savings represent 8% of the emissions of the PC plant (mainly due to the avoidance of consuming fossil fuels as in the conventional MeOH synthesis process). The results demonstrate that there is a net but small potential for CO 2 emissions reduction; assuming that such CCU plants are constructed in http://dx.Europe to meet the MeOH demand growth and the quantities that are currently imported, the net CO 2 emissions reduction could be of 2.71 MtCO 2 /yr.

“…[6] Various (Me)MoS 2 -based catalysts can be used for catalytic synthesis gas conversion. [7][8][9][10] A high content of sulfidic impurities in the feedstock (50-100 ppm H 2 S) helps inhibits sulfur removal from these catalysts, preventing deactivation and extending catalyst life. [11,12] Sulfide catalysts are more resistant to carbon deposition, than conventionally applied oxide ZnCu and ZnCr catalysts.…”

Effect of Promoter Nature on Synthesis Gas Conversion to Alcohols over (K)MeMoS₂/Al₂O₃ Catalysts

et al. 2020

The influence of the promoter nature and of a modifier in (K)(Me)MoS2/Al2O3 (Me=Fe, Co, Ni) catalysts on the conversion and selectivity of products of synthesis gas conversion to alcohols and jnl oxygenates was investigated. Relationships between promoter nature, hydrocarbon chain length and selectivity in the formed alcohols were established. Electronic structure of a promoter atom in an active site (AS) was found to strongly affect selectivity of alcohol formation. Promotion of the S‐edge by Fe, Co or Ni suppressed hydrogen activation, which resulted in a lower synthesis gas conversion. Promotion of the M‐edge by Fe, Co, or Ni entailed the formation of double vacancies which are active sites of synthesis gas conversion. Potassium affected the oxophilicity of Mo atoms and reduced Co/Ni‐promoted MoS AS. It decreased the probability of C−O bond breaking in the adsorbed intermediate and shifted selectivity from the formation of alkyl towards alkoxide fragments over these catalysts.
