    Abstract: A system and method of thermally processing carbonaceous materials, and especially sustainably cultivated woody biomass or cellulosic biomass sorted from municipal solid waste, to produce green fuel, such as diesel, sustainable aviation fuel and other beneficial by-products, including biochar. Synthesis gas is made by gasifying sustainably grown biomass, the thermal energy from which is used to create steam for treatment of biochar by-product to produce higher value activated carbon. Oxygen for the gasifier and hydrogen for a Fischer Tropsch (FT) or other catalytic synthesis stage of the process are generated by electrolysis of water using sustainably produced electricity. The gasification and electrolysis processes are operated to produce a 2:1 ratio of hydrogen to carbon monoxide needed for FT or other catalytic synthesis. The hydrocarbon product is distilled as required to produce either green alcohols or green diesel fuel and sustainable aviation fuel.

    Abstract: Fuel composition comprising: (a) a base fuel suitable for use in an internal combustion engine; (b) a tetraalkylethane compound having the formula (I) : wherein Ar represents an aryl group and each X is independently selected from a hydrogen atom, substituted or unsubstituted, straight chain or branched C1-C12 alkyl group, (CH2)nOH or (CH2)nNH2, wherein n is in the range of 1 to 9, provided that at least one of the X groups in each CX3 group is a hydrogen atom; and c) an alkylbenzene compound having the formula (II) wherein each R1-R6 group is independently selected from hydrogen and a C1-C15 alkyl group, wherein at least one of the R1-R6 groups is a C1-C6 alkyl group. The fuel composition of the present invention provides improved power and acceleration benefits, as well as increased flame speed and burn duration.

    Abstract: Some variations provide a process for producing mixed alcohols, comprising: purifying a biogas feedstock to generate a renewable natural gas stream comprising methane; introducing the renewable natural gas stream into a methane-to-syngas unit operated at effective conditions to convert the methane to a first syngas stream containing at least H2, CO, and CO2; purifying the first syngas stream, including separating the CO2 from the first syngas stream, and optionally separating some of the H2 from the first syngas stream, thereby generating a clean syngas stream; introducing the clean syngas stream into a mixed-alcohol reactor operated at effective alcohol synthesis conditions with an alcohol-synthesis catalyst, thereby generating mixed alcohols; and purifying the mixed alcohols to generate a mixed-alcohol product. The mixed-alcohol product may be blended with a hydrocarbon fuel, such as gasoline, to produce a blended fuel. The blended fuel has significantly lower carbon intensity than the base hydrocarbon fuel.
