“…Steam reforming of bio-syngas with an additional natural gas feedstock is also considered as a viable option. [102][103][104][105][106] The Fe/Cu/K catalyst on Al 2 O 3 /SiO 2 support has recently demonstrated high FT activity on bio-syngas. [107] The key challenge of using bio-syngas is the clean-up step to separate tar, and other impurities prior to conversion steps.…”

Next-generation biofuels, such as cellulosic bioethanol, biomethane from waste, synthetic biofuels obtained via gasification of biomass, biohydrogen, and others, are currently at the center of the attention of technologists and policy makers in search of the more sustainable biofuel of tomorrow. To set realistic targets for future biofuel options, it is important to assess their sustainability according to technical, economical, and environmental measures. With this aim, the review presents a comprehensive overview of the chemistry basis and of the technology related aspects of next generation biofuel production, as well as it addresses related economic issues and environmental implications. Opportunities and limits are discussed in terms of technical applicability of existing and emerging technology options to bio-waste feedstock, and further development forecasts are made based on the existing social-economic and market situation, feedstock potentials, and other global aspects. As the latter ones are concerned, the emphasis is placed on the opportunities and challenges of developing countries in adoption of this new industry.

“…On the other hand, methanol can be produced from widely available agricultural, forest, and municipal waste as a renewable feedstock that can be mixed with lower-cost inputs such as coal and natural gas as fossil feedstocks. 19 If the water-to-methanol molar ratio (w) in the methanol solution is less than unity, one can assume that all of the steam is reduced to hydrogen by methanol according to eq 4. The rest of the methanol not oxidized by steam decomposes to CO and H 2 according to eq 1 if there is enough heat for 100% conversion.…”

“…The mixture heat value of a neat fuel (in units of kJ/L) can be determined from the fresh charge's molar density (ρ) after intake valve closure (IVC), the relative air/fuel ratio (λ), the mean lower heating value (LHV), and the stoichiometric oxygen (o st ), as shown in eq 6. 19 These parameters will be defined and determined for any gaseous fuel mixture in the next section.…”

This article investigates theoretically the products from adiabatic combustion of synthesis gas reformed out of aqueous methanol with a variable gasoline−methanol mixture assuming chemical equilibrium. Previous research has generally focused on the combustion of a given fixed fuel composition, whereas in this article the composition of the fuel is varied by three different parameters: the amount of water in the aqueous methanol used as the synthesis gas feedstock, the amount of methanol in the gasoline−methanol mixture, and the ratio of synthesis gas energy to total fuel energy. The effects of these parameters on the adiabatic flame temperature and combustion product distribution are determined. The method used in this article allows the above parameters and the air/fuel ratio parameter to vary in equation sets derived using Lagrange undetermined multipliers in order to determine the combustion temperature and products with a computer solution. Stoichiometric combustion of synthesis gas reformed out of an equimolar water−methanol mixture causes a decrease in the NO ratio by 20% compared with methanol and 40% compared with gasoline under equilibrium conditions, whereas the adiabatic flame temperature decreases by only 50 and 100 K, respectively. Stoichiometric combustion of synthesis gas reformed out of neat methanol causes a higher adiabatic flame temperature and higher NO x emissions than stoichiometric combustion of gasoline or methanol. However, neat-methanolbased synthesis gas has a higher power density and extends the lean flammability limit of the engine more efficiently than aqueous-methanol-based synthesis gas because the reforming enthalpy of neat methanol is higher than that of aqueous methanol. Hydrogen-rich synthesis gas fuels should be combusted with lean air/fuel ratios at part load to increase the thermal efficiency, combustion stability, and control emissions simultaneously. If the road load increases, the engine charge's energy density and motor octane number will be increased by substitution of synthesis gas with liquid fuel while decreasing the air/fuel ratio simultaneously.
