Reformulated Blendstock for Oxygenate Blending (RBOB) is a gasoline futures contract traded on the New York Mercantile Exchange (NYMEX). It is the benchmark futures contract for wholesale gasoline in the United States.
Catalytic reforming is a chemical process used to convert naphthas from crude oil into liquid products called reformates, which are premium "blending stocks" for high-octane gasoline. The process converts low-octane linear hydrocarbons (paraffins) into branched alkanes (isoparaffins) and cyclic naphthenes , which are then partially ...
Butane (/ ˈ b juː t eɪ n /) is an alkane with the formula C 4 H 10. Butane exists as two isomers, n-butane with connectivity CH 3 CH 2 CH 2 CH 3 and iso-butane with the formula (CH 3) 3 CH. Both isomers are highly flammable, colorless, easily liquefied gases that quickly vaporize at room temperature and pressure.
Blended from pure, dry propane (refrigerant designator R-290) and isobutane (R-600a) the blend "R-290a" has negligible ozone depletion potential, very low global warming potential and can serve as a functional replacement for R-12, R-22, R-134a and other chlorofluorocarbon or hydrofluorocarbon refrigerants in conventional stationary ...
Alkylate is a component of choice in gasoline, because it is free of aromatics and olefins. About 11% of the gasoline winter pool in the U.S. is made up of alkylate. In the gasoline summer pool, the content of alkylate can be as high as 15% because lower Reid vapor pressure (RVP) reduces the possibility to blend butane.
can be produced from plant matter not connected to food supplies, preventing a fuel-price/food-price relationship. [10] [11] [12] [27] assuming that it is produced from residual lignocellulosic feedstocks, blending isobutanol with gasoline may reduce GHG emissions considerably. [41]
The rising price of oil in the 1970s resulted in a slump in consumption, which meant there was a considerable excess of refining capacity throughout Europe. In August 1981 BP Oil announced that the BP Kent refinery would close in 1982 with the loss of 1,670 workers plus another 1,000 construction jobs in the area. [ 20 ]
Petroleum naphtha is an intermediate hydrocarbon liquid stream derived from the refining of crude oil [1] [2] [3] with CAS-no 64742-48-9. [4] It is most usually desulfurized and then catalytically reformed, which rearranges or restructures the hydrocarbon molecules in the naphtha as well as breaking some of the molecules into smaller molecules to produce a high-octane component of gasoline (or ...
