“…They suggested that this phenomenon occurred owing to the fast combustion development during the premixed conditions. However, there are certain drawbacks associated with the use of n-butanol-gasoline mixture in a direct injection SI engine owing to the cold start, lack of fuel atomization and dilution of the oil [27]. Chen et al [28] evaluated the impact of n-butanol addition by percentage of (15%, 30% and 50%) in gasoline fuels on a turbocharged gasoline direct injection (GDI) type.…”

“…Much of the current literature on butanol additive pays particular attention to n-butanol in both spark and compression ignition engines; see, e.g., [23,24,[26][27][28][29][30][31]33] and [34][35][36][37]39,44], respectively. Some researchers have also attempted to draw fine distinctions using different types of butanol isomers such as isobutanol-see, e.g., [20,32,[47][48][49][50][51][52]-and tert-butanol-see, e.g., [53].…”

“…15,23 Because both ketones and furans are known for their solvent characteristics, investigations on different seal materials were conducted. 24 These investigations revealed increased swelling in the case of ethylene propylene diene monomer (EPDM) rubber, fluoroelastomer (FKM) and nitrile butadiene rubber (NBR) for both 2-butanone and 2-methylfuran.…”

“…These characteristics enable high efficiency improvements compared to RON95 gasoline fuel. [13][14][15][16] Therefore, ethanol is defined as the benchmark biofuel for SI engines. As a second benchmark, RON95 (EN228, EN51626-1) gasoline was chosen to represent today's most commonly used conventional fuel for SI engines in the European market.…”

Increasing carbon dioxide accumulation in earth's atmosphere and the depletion of fossil resources pose huge challenges for our society and, in particular, for all stakeholders in the transportation sector. The Cluster of Excellence 'Tailor-Made Fuels from Biomass' at RWTH Aachen University establishes innovative and sustainable processes for the conversion of whole plants into molecularly well-defined fuels exhibiting tailored properties for low-temperature combustion engine processes, enabling high efficiency and low pollutant emissions. The concept of fuel design, that is, considering fuel's molecular structure to be a design degree of freedom, aims for the simultaneous optimisation of fuel production and combustion systems. In the present contribution, three examples of tailor-made biofuels are presented. For spark ignition engines, both 2-methylfuran and 2-butanone show increased knock resistance compared to RON95 gasoline, thus enabling a higher compression ratio and an efficiency gain of up to 20% at full-load operation. Moreover, both fuels comprise a good mixture formation superior to the one of ethanol, especially under difficult boundary conditions. For compression ignition engines, 1-octanol enables a remarkable reduction in engine-out soot emissions compared to standard diesel fuel due to the high oxygen content and lower reactivity. This advantage is achieved without sacrificing the high indicated efficiency and low NO X emissions.

“…In literature, the fuels ethanol, c-valerolactone, ethyllevulinate, iso-butanol, 2-butanol and 2-butanone have been proposed as bio-based gasoline fuels having all a Research Octane Number equal or larger than 100 qualifying them as fuels for sparkignition engines. [72][73][74] The fuels are produced from lignocellulosic biomass. As none of the fuels can be produced from lignin, its utilization is not considered in the RNFA, while lignin combustion is used for an internal energy supply in the PNFA.…”

Early‐stage evaluation of biorefinery processing pathways using process network flux analysis

With growing interest in the biomass value chain, a multitude of reactions are proposed in literature for the conversion of biomass into a variety of biofuels. In the early design stage, data for a detailed design is scarce rendering an indepth analysis of all possibilities challenging. In this contribution, the screening methodology process network flux analysis (PNFA) is introduced assessing systematically the cost and energy performance of processing pathways. Based on the limited data available, a ranking of biorefinery pathways and a detection of bottlenecks is achieved by considering the reaction performance as well as the feasibility and energy demand of various separation strategies using thermodynamic sound shortcut models. PNFA is applied to a network of six gasoline biofuels from lignocellulosic biomass. While 2-butanol is ruled out due to a lack in yield and selectivity, iso-butanol and 2-butanone are identified as economically promising fuels beyond ethanol. Topical area: Process Systems Engineering.
