  • Publication number: 20130001130
    Abstract: A fluidized catalytic cracking process and system that provide for the processing of hydrocarbon feedstocks to selectively produce a middle distillate boiling range product and lower olefins. The inventive process uses two riser reactors each having associated therewith a separator/stripper for separating the cracked product and cracking catalyst received from the respective riser reactor and a single regenerator for regenerating coked or spent cracking catalyst received from the separator/strippers. The two riser reactors, two separator/strippers and regenerator are operatively integrated to provide a process system for carrying out the process of the invention.

  • 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.
