Abstract: A process is disclosed for polishing a relatively highly pure stream of aromatic material bound for use as a petrochemical feedstock wherein the stream includes olefins and especially concerning, diolefins. The process comprises hydrotreating the highly pure aromatic stream with an unsulfided cobalt molybdenum catalyst that has low saturating activity for the aromatic but is active for saturating olefins and diolefins.

Abstract: Processes relating to thermal activation (or cracking) of ethane to an intermediate, low purity raw ethylene stream in a first stage. This stream is then mixed with a stream of biomass-derived ethanol that may contain four volume percent or more of water. The resulting mixture is reacted over a suitable catalyst at temperatures and pressures suitable to produce gasoline-range and diesel-range blend stock.

Abstract: A process for converting ethane to liquid fuels may involve directing an ethane stream into an ethane cracking unit to produce an intermediate hydrocarbon stream and a raw ethylene stream; fractionating the intermediate hydrocarbon stream into a gasoline fraction and a diesel fraction; introducing the raw ethylene stream into an oligomerization unit; contacting the raw ethylene stream with an oligomerization catalyst to produce a liquid hydrocarbon stream and an off-gas stream; recycling an off-gas recycle stream from an off-gas stream of the oligomerization unit separation unit to an inlet of the oligomerization reactor; introducing at least part of the off-gas stream into a hydrogenation reactor to remove unconverted olefins; separating a hydrogen component and a plurality of light paraffin components in a post hydrogenation reactor separation unit using a PSA technology or membrane technology; and recycling the light paraffins stream into the ethane cracking unit.

Abstract: Converting ethane may include directing a gaseous stream from a gas well into a fractionator for fractionating and producing a post-fractionator ethane stream, which is directed into a thermal activation unit for heating and raising the temperature of the post-fractionator ethane stream thereby creating an activated ethane stream, which is directed into a quench tower thereby creating a quenched stream, which may be converted in a catalytic conversion unit to a mixed product stream containing hydrogen and C1-C15 hydrocarbons; directing the mixed product stream into a first separation unit forming a stream of C4+ hydrocarbon product and a stream of C1-C3 hydrocarbons; directing the stream of C1-C3 hydrocarbons into a catalytic hydrogenation reactor thereby imparting hydrogen into a post-hydrogenation reactor stream, which is directed directly into a second separation unit thereby creating a light hydrocarbons recycle stream, which may be recycled into the thermal activation unit, and a hydrogen and methane str

Abstract: Systems relating to thermal activation (or cracking) of ethane to an intermediate, low purity raw ethylene stream in a first stage. The system then mixes this stream with a stream of raw biomass-derived ethanol that may contain more than four volume percent of water. The resulting mixture is reacted over a suitable catalyst at temperatures and pressures suitable to produce gasoline-range and diesel-range blend stock.

Abstract: A process of producing a light oil stream from slurry oils. The process begins by obtaining slurry oil from a fluid catalytic cracking unit. The slurry oil is then flowed over a fixed bed catalyst, consisting essentially of a non-metal catalyst, to produce a processed slurry oil. The processed slurry oil is then separated by boiling point to separate out the light oil stream.
