“…Given the Raney Ni catalyst could be poisoned by water in the hydrogenation process [36], the water in the raw bio-oil samples should be removed. Since n-heptane severed as the vital medium in the hydrogenation process [35], two phase of mixed bio-oil samples was separated by the optimum solvent (n-heptane).…”

“…Nonetheless, aromatics and cycloalkanes cannot be generated by the two technologies. On the other hand, the promising pathway for the production of cycloalkanes are the hydrocycloaddition of aromatic hydrocarbons [35][36][37][38]. To pursue the precursors of renewable cycloalkanes for jet fuels, highly desirable aromatic hydrocarbon in the jet fuel range (C 8 -C 16 ) should be generated.…”

Enhanced carbon yields of jet fuel range alkanes were manufactured from cofeeding of lignocellulosic biomass with plastics. The consecutive processes proceeded via the cofeed catalytic microwave-induced pyrolysis and hydrogenation process. In the co-feed catalytic microwave pyrolysis by using ZSM-5 as the catalyst, parent ZSM-5 fabricated by hydrothermal and calcined treatments contributed to the increase of surface area as well as the formation of more mesopores. Liquid organics with enhanced carbon yield (40.54%) were more principally lumped in the jet fuel range from the co-feed catalytic microwave pyrolysis performed at the catalytic temperature of 375 °C with the plastics to biomass ratio of 0.75. To manufacture homemade Raney Ni catalyst, the BET surface area, pore surface area, and pore volume of the homemade Raney Ni catalyst were considerably improved when the Ni-Al alloy was dissolved by the NaOH solution. In the hydrogenation process, we observed the three species of raw organic derived from the co-feed catalytic microwave pyrolysis were almost completely converted into saturated hydrocarbons under a low-severity condition. The improved carbon yield (38.51%) of hydrogenated organics regarding co-reactants of biomass and plastics predominantly match jet fuels. In the hydrogenated organics, over 90% selectivity toward alkanes with the carbon number in the jet fuel range was attained. In this respect, these hydrogenated organics with high amounts of renewable cycloalkanes can be potentially served as high-density jet fuels or additives for

“…Nowadays, most of the jet fuel that is commercialized is derived from the refining process of conventional crude oil . Hydrocarbon fuels for aviation can also be produced by biomass gasification, aqueous‐phase catalytic transformation of soluble sugars, Fischer‐Tropsch synthesis, and/or hydrogenation of biodiesels or vegetable oils .…”

Short‐chain esters enriched biofuel obtained from vegetable oil using molecular distillation

et al. 2017

Aviation fuels used in gas‐turbine engine powered aircraft are mainly obtained from the distillation of mineral oil. These jet fuel molecules present carbon chain length of C8 to C16 in the same range of fossil kerosene and have high calorific values and a great cold behaviour. With the increase in consumption of jet fuels, it has become extremely important to develop alternative fuels with adequate properties that could be capable of fulfilling the aviation industry requirements. In this context, aviation alternative fuel originated from sustainable raw materials must meet a set of safety requirements and should exhibit similar physicochemical properties to mineral kerosene. In this study the production of a short‐chain esters enriched biofuel using molecular distillation of FAME obtained from babassu oil was evaluated. Operational conditions were assessed to obtain high mass yields and high ester content in the carbon chain length range of kerosene. A fuel with properties close to those of aviation biofuels was obtained at 140 °C. At this temperature, more than 80 % of the esters in the product composition were within the desired range and there was a mass recovery higher than 88 %. In addition, the short‐chain esters enriched biofuel was blended with fossil kerosene at different concentrations and its properties were analyzed in order to study the effects of the gradual addition of this biofuel stream to commercial aviation kerosene. Density, heating value, freezing temperature, and pour point were evaluated. A mixture up to 6.0 % g/g accomplished the specification limits established by ASTM D1655.

“…For the natural gas scenario, it requires 202 metric tons of natural gas per day to meet the CO demand. The high amount of char produced can be gasified to supply a fraction of the total CO requirement for the calcium formate regeneration process . However, we find that it is difficult to separate char from the pyrolysis heating medium calcium oxide.…”

“…The catalytic pyrolysis process has been proposed to address the shortcomings of RGD fuel production from cellulosic feedstock via fast pyrolysis . In the catalytic pyrolysis process, oxygen is removed as carbon dioxide by physically contacting biomass with the ZSM‐5 group of catalysts at temperatures between 400°C and 500°C.…”

An economic analysis was performed to determine the economic potential and commercialization barriers of producing renewable gasoline and diesel (RGD) fuel blendstocks via formate‐assisted pyrolysis (FAsP) followed by hydrodeoxygenation processes. A process model was simulated using Aspen Plus® to estimate material and energy balances for the conversion of 2000 dry MT per day of pine sawdust. Scenarios were considered for the regeneration of formate salts from either ‐biomass‐derived and natural‐gas‐derived carbon monoxide. The material and energy balances were used to calculate capital and operating costs of RGD fuel production. An economic model was built using capital and operating costs to estimate the minimum selling price (MSP) of RGD fuel. The MSP of RGD fuels were estimated at $4.58 per gallon of gasoline equivalent (GGE) and $4.80 per GGE for natural gas and biomass‐derived CO scenarios, respectively. The total capital investments of these plants were $448 million and $497 million. The feedstock cost was found to be the major cost contributor to the MSP of RGD fuel. Improving FAsP process yields will significantly reduce the production cost of RGD fuel. It has been learned that an increase in deoxygenation of bio‐oil in pyrolysis reactor decreases the capital and operating costs of bio‐oil upgrading to RGD fuel. © 2017 Society of Chemical Industry and John Wiley & Sons, Ltd
