Abstract
This invention relates to processes and systems for converting acyclic hydrocarbons to alkenes, cyclic hydrocarbons and/or aromatics, for example converting acyclic C5 hydrocarbons to cyclopentadiene in a reactor system. The process includes heating an electrically-conductive reaction zone by applying an electrical current to the first electrically-conductive reaction zone; and contacting a feedstock comprising acyclic hydrocarbons with a catalyst material in the electrically-conductive reaction zone under reaction conditions to convert at least a portion of the acyclic hydrocarbons to an effluent comprising alkenes, cyclic hydrocarbons, and/or aromatics.
Claims24
A process for converting acyclic hydrocarbons to alkenes, cyclic hydrocarbons, and/or aromatics in a reactor system, wherein the process comprises:
- heating an electrically-conductive monolith reactor housed within the reactor system, said monolith reactor defining an electrically conductive reaction zone, by applying an electrical current to a plurality of electrodes in contact with the monolith reactor so that a direction of current flow through the monolith reactor is substantially orthogonal to a direction of flow of the feedstock through a channel within the monolith reactor;
- and
- contacting a feedstock comprising acyclic hydrocarbons with a catalyst material in the electrically-conductive reaction zone under reaction conditions sufficient to convert at least a portion of the acyclic hydrocarbons to an effluent comprising alkenes, cyclic hydrocarbons, and/or aromatics, wherein the catalyst material is at least partially coated on an interior of the channel of the zone monolith reactor.
A reaction system adapted for converting acyclic hydrocarbons to alkenes, cyclic hydrocarbons, and/or aromatics, wherein the reaction system comprises:
- one or more electrically-conductive monolith reactors housed within the reactor system, the one or more monolith reactors being configured to convert, under reaction conditions, at least a portion of a feedstock stream including acyclic hydrocarbons to an effluent stream including alkenes, cyclic hydrocarbons, and/or aromatics, wherein the one or more monolith reactors each independently comprises:
- a catalyst material least partially coated on an interior channel of the monolith reactor;
- a feedstock stream inlet;
- an effluent stream outlet;
- and
- a current generator configured to supply a current to and heat the electrically-conductive reaction zone by supplying the current to a plurality of electrodes in contact with the monolith reactor so that a direction of current flow through the monolith reactor is substantially orthogonal to a direction of flow of the feedstock through the interior channel of the monolith reactor.
