Depending the alkyls, the trialkylamines of February 18, 2020 can have varied uses
It may not be as hydrophobic as hydrocarbons. I ignore if its combustion produces more NOx
than a hydrocarbon. Slightly more efficient than an alkane, and if burnt with air, the engine power increases a bit but the consumption too. Mass-poduction is easy and efficient, the product is accurate.
From propene and n-butene
, C+N~11.5 make a good rocket fuel and a jet fuel
probably, with a good liquid range, flash point and self-ignition. Presently the C3
fraction is torched at gas and oil wells, so using it as a fuel would reduce the CO2
emissions. The complete fraction could be fed to the reactor, the alkenes would react, the alkanes at the output easily separated and pyrolysed to reinject alkenes.
Gas and oil wells have no chemical processing presently. Using this fraction would need an ammonia and hydroamination unit at the well, or on a boat that collects the stored fraction, or onshore, or to transport the fraction overseas which isn't done up to now as butane is too cheap. Refineries have already an ammonia and hydroamination unit, propene is available but it serves, butene can be obtained from ethylene.
Ethylene and propene would target gasoline's molar mass but not the octane number. Isobutene
might achieve a good octane number (or not, due to the amine) but with C+N=13, the upper end for gasoline
. Maybe ethylene and isobutene achieve both. Alkylation is a cheap competitor.n-alkenes around hexene
would make a synthetic Diesel fuel emitting no fine particles
hopefully, thanks to uniform autoignition temperature, lack of aromatics, high H/C ratio, and clean amine flame. Hexene is typically obtained from ethylene at refineries, so the fuel needs more processing than presently.
