Abstract
An internal static mixing system such as a disperser of mesh wire or expanded metal co-knit with a multi filament material selected from inert polymers, catalytic polymers, catalytic metals or mixtures in combination with a vertical reactor having a reaction zone and the disperser disposed in said reaction zone, particularly for carrying out paraffin alkylation using acid catalyst is disclosed. The wire mesh provides the structural integrity of the system as well as the open space required in reactors for the movement of vapors and liquids though the system. The disperser may be in sheets, bundles or bales or positioned within a frame.
Claims13
A combination for carrying out catalytic reactions in concurrent downflow comprising a vertical reactor and a disperser disposed in said vertical reactor as a plurality of vertically arranged, transverse mats within and across said vertical reactor, said disperser comprising at least 50 volume % open space and comprising mesh wire co-knit with a multi filament component or expanded metal intertwined with a multi filament component, said multi filament selected from inert polymers, catalytic polymers, catalytic metals or mixtures thereof.
A combination for carrying out catalytic reactions in concurrent downflow comprising a vertical reactor, a disperser disposed in said vertical reactor said disperser comprising sheets, bundles or bales of a co-knit wire and a multi filament component or combinations thereof, comprising at least one partially liquid reactant, catalyst and reaction conditions to maintain said partially liquid reactant at a boiling point.
A combination for carrying out catalytic reactions in concurrent downflow comprising a vertical reactor, a disperser disposed in said vertical reactor as a plurality of vertically arranged, transverse mats within and across said vertical reactor, comprising at least one partially liquid reactant, catalyst and reaction conditions to maintain said partially liquid reactant at a boiling point wherein said disperser comprises a co-knit mesh of wire and polymer mesh.
A combination for carrying out catalytic reactions in concurrent downflow comprising a vertical reactor, a disperser disposed in said vertical reactor as a plurality of vertically arranged, transverse mats within and across said vertical reactor, comprising at least one partially liquid reactant, catalyst and reaction conditions to maintain said partially liquid reactant at a boiling point wherein said disperser comprises co-knit mesh wire and fiberglass.
A combination for carrying out catalytic reactions in concurrent downflow comprising a vertical reactor, a disperser disposed in said vertical reactor as a plurality of vertically arranged, transverse mats within and across said vertical reactor, comprising at least one partially liquid reactant, catalyst and reaction conditions to maintain said partially liquid reactant at a boiling point wherein said disperser comprises a mesh of co-knit wire and a multi filament component comprising polytetrafluoroethylene, steel wool, polypropylene, PVDF, polyester or combinations thereof.
A combination for carrying out catalytic reactions in concurrent downflow comprising a vertical reactor, a disperser disposed in said vertical reactor as a plurality of vertically arranged, transverse mats within and across said vertical reactor, comprising at least one partially liquid reactant, catalyst and reaction conditions to maintain said partially liquid reactant at a boiling point wherein said disperser comprises mesh wire or expanded metal co-knit with a multi filament catalytic material of sulfonated vinyl resin, Ni, Pt, Co, Mo, Ag or mixtures thereof.
A disperser comprising mesh wire or expanded metal co-knit with a multi filament catalytic material of sulfonated vinyl resin alone or with a metal selected from the group consisting of Ni, Pt, Co, Mo, Ag or mixtures thereof.
