Simulation Study of Ionic Liquid Utilization for Desulfurization of Model Gasoline
With the increased amount of focus is being put towards reducing the emissions results from fossil fuel usually composed of hydrocarbons and impurities. The study aim at utilizing the ability of 1-octyl-3-methylimidazolium tetrafluoroborate [OMIM][BF4]. Ionic liquid as the suitable solvent for the extraction of the thiophene and its derivatives from the model gasoline. The proces...
متن کاملExploiting hydrophobic borohydride-rich ionic liquids as faster-igniting rocket fuels.
A family of hydrophobic borohydride-rich ionic liquids was developed, which exhibited the shortest ignition delay times of 1.7 milliseconds and the lowest viscosity (10 mPa s) of hypergolic ionic fluids, demonstrating their great potential as faster-igniting rocket fuels to replace toxic hydrazine derivatives in liquid bipropellant formulations.
متن کاملPrediction of Dual-Mode Spacecraft Propellant Performance of Binary and Ternary Ionic Liquid Mixtures
The theoretical chemical and electrospray performance of [Bmim][dca], [Bmim][NO3], or [Emim][EtSO4] mixed with HAN in aqueous solution for dual mode chemical monopropellant/bipropellant and electrical electrospray rocket propulsion have been investigated. A ternary mixture comprised of 80 percent HAN, 20 percent of each ionic liquid fuel, and no water yielded the maximum specific impulse and ch...
متن کاملDecomposition of Ionic Liquid Ferrofluids for Multi-Mode Spacecraft Propulsion
Ionic liquid ferrofluids based on mixtures of [Emim][EtSO4] and [Bmim][NO3] fuels and hydroxylamonium nitrate oxidizer were synthesized by adding iron oxide nanoparticles. The resulting propellants were then tested for decomposition capability. Spot plate testing indicated that the temperature required to initiate rapid decomposition dropped from 115 o C to 75 o C with a 30% by weight addition ...
متن کاملSpecific Impulse and Ignition Delay Time Assessment for DMAZ with Liquid Oxidizers for an Upper Stage Rocket Engine
2-Dimethyl amino ethyl azide (DMAZ) has attracted much attention as a suitable liquid fuel replacement for monomethyl hydrazine (MMH) and unsymmetrical dimethyl hydrazine (UDMH) in propellant systems because, in contrast to these fuels, it is noncarcinogen. In this research, performance, and ignition delay time of DMAZ were studied with common liquid oxidizers such as inhibited red fuming n...
