  • Patent number: 11220648
    Abstract: Naphtha boiling range compositions are provided that can have improved combustion properties (relative to the research octane number of the composition) in spark ignition engines and/or compression ignition engines. The improved combustion properties can be achieved by controlling the total combined amounts of n-paraffins and isoparaffins that include a straight-chain propyl group (R1—CH2—CH2—CH2—R2). For such a straight-chain propyl group, R2 can correspond to any convenient CxHy group that can appear in a paraffin or isoparaffin. R1 can correspond to a hydrogen atom, making the straight-chain propyl group a terminal n-propyl group; or R1 can correspond to any convenient CxHy group that can appear in a paraffin or isoparaffin.

  • Patent number: 8237004
    Abstract: A process for making products with low hydrogen halide, comprising: a) stripping or distilling an effluent from a reactor into a first fraction having an amount of hydrogen halide, and a second fraction having a reduced amount of hydrogen halide; wherein the reactor comprises: an ionic liquid catalyst having a metal halide, and a hydrogen halide or an organic halide; and b) recovering one or more product streams, from the second fraction, having less than 25 wppm hydrogen halide. In one embodiment the ionic liquid catalyst has metal halide; and the recovering recovers propane, n-butane, and alkylate gasoline having less than 25 wppm hydrogen halide. In another embodiment the recovering uses a distillation column having poor corrosion resistance to hydrogen halide; and the distillation column does not exhibit corrosion. There is also provided an alkylate gasoline having less than 5 wppm hydrogen halide, a high RON, and low RVP.

  • Patent number: 8151880
    Abstract: A method for producing alkylated hydrocarbons is disclosed. Formation fluid is produced from a subsurface in situ heat treatment process. The formation fluid is separated to produce a liquid stream and a first gas stream. The first gas stream includes olefins. The liquid stream is fractionated to produce at least a second gas stream including hydrocarbons having a carbon number of at least 3. The first gas stream and the second gas stream are introduced into an alkylation unit to produce alkylated hydrocarbons. At least a portion of the olefins in the first gas stream enhance alkylation. The alkylated hydrocarbons may be blended with one or more components to produce transportation fuel.
