Systems for reforming a feedstock comprising paraffins and naphthenes. A first reactor containing a first reforming catalyst is operable to maintain a temperature and pressure that facilitates conversion of naphthenes in the feedstock to aromatics while facilitating conversion of less than 50 wt. % of paraffins in the feedstock to olefins. A first separator receives and separates the first effluent that is produced in the first reactor to produce a first fraction enriched in aromatics and a second fraction enriched in paraffins. A second reactor containing a second reforming catalyst is operable to maintain a temperature and pressure that facilitates conversion of at least 50 wt. % of paraffins in the second fraction to olefins. The system is operable to produce a liquid hydrocarbon product suitable for use as a blend component of a liquid transportation fuel.

Selective naphtha reforming systems

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.

Highly selective olefin removal with unsulfided hydrotreating catalysts

Process for reforming a hydrocarbon feedstock comprising paraffins and naphthenes. A hydrocarbon feedstock is separated to produce a first fraction enriched in naphthenes and a second fraction that is enriched in paraffins. The first fraction is contacted with a first reforming catalyst in a first reactor that is maintained at a temperature and pressure that facilitates conversion of naphthenes to aromatics. The second fraction is contacted with a second reforming catalyst in a second reactor at a temperature and pressure that converts at least 50 wt. % of paraffins in the second fraction to olefins. The process produces a liquid hydrocarbon reformate product suitable for use as a blend component of a liquid transportation fuel.

A hydrocarbon feedstock is contacted with a first reforming catalyst in a first reactor at a temperature and pressure that facilitates conversion of naphthenes to aromatics while converting less than 50 wt. % of paraffins in the feedstock to olefins, thereby producing a first effluent that is separated into a first fraction that is enriched in aromatics and a second fraction that is enriched in paraffins. The second fraction is contacted with a second reforming catalyst in a second reactor at a temperature and pressure that converts at least 50 wt. % of paraffins in the second fraction to olefins. The process produces a liquid hydrocarbon reformate product suitable for use as a blend component of a liquid transportation fuel.

Selective naphtha reforming processes

Systems for reforming a hydrocarbon feedstock, where the system is operable to selectively reform different sub-components of the hydrocarbon feedstock using at least two structurally-distinct reforming catalysts. Advantages may include a decreased rate of reforming catalyst deactivation and an increased yield of a liquid hydrocarbon reformate product that is characterized by at least one of an increased octane rating and a decreased vapor pressure compared to the liquid hydrocarbon reformate product of conventional one-step reforming systems.

A method of cleaning plugged or dirty porous metallic filter elements to regain filter activity, comprising the steps of: steaming a filter element for a first period of time; submerging the filter element in a first solution; and exposing the first solution to ultrasound waves for a second period of time.

There is provided a process for converting high free fatty acid containing feedstock such as acidulated soapstock into hydrocarbon compound especially fuel range hydrocarbons using amidation as a pretreatment step followed by hydroprocessing.

Production of hydrocarbon from high free fatty acid containing feedstocks

Methods and apparatus relate to processing of petroleum with a bed having a sorbent based diluent that the petroleum contacts upon passing through the bed. Magnetic properties of the sorbent and any other material, such as zeolite, used in the bed enable separation of such bed constituents based on a sulfided form of the sorbent being magnetic in contrast to a non-sulfided form of the sorbent being non-magnetic. Dividing the bed constituents into first and second portions by magnetic separation facilitates in selective replacing and/or regenerating the first portion independent of the second portion.
