Abstract
A hydrocarbon dehydrogenation process includes providing the hydrocarbon feed to a reactor. The hydrocarbon feed includes at least one hydrocarbon selected from light paraffins, heavy paraffins, or combinations thereof. The process further includes introducing an inert diluent into the feed stream, contacting the feed stream and the inert diluent with a catalyst in the reactor, and flowing an effluent stream out of the reactor.
Claims20
A process for dehydrogenation of a hydrocarbon feed, comprising:
- providing the hydrocarbon feed in a feed stream to an inlet of a reactor, the hydrocarbon feed comprising at least one hydrocarbon selected from light paraffins or heavy paraffins;
- introducing an inert diluent into the feed stream;
- contacting the feed stream and the inert diluent with a catalyst in the reactor under dehydrogenation reaction conditions;
- and
- removing an effluent stream from the reactor at an outlet.
A process for dehydrogenating a light paraffin feed, comprising:
- providing the light paraffin feed to an inlet of a reactor, the light paraffin feed comprising hydrogen and at least one light paraffin of propane, butane or pentane;
- introducing at least one inert diluent selected from methane and nitrogen into the light paraffin feed;
- contacting the light paraffin feed and the inert diluent with a catalyst in the reactor under dehydrogenation reaction conditions;
- and
- removing an effluent stream from the reactor at an outlet;
- wherein the light paraffin feed has a ratio of hydrogen to light paraffin in a range of 0.1:1 to 1.0:1 on a molar basis and a ratio of inert diluent to light paraffin in a range of about 0.1:1 to about 3.0:1 on a molar basis.
A process for dehydrogenating a heavy paraffin feed, comprising:
- providing the heavy paraffin feed to an inlet of a reactor, the heavy paraffin feed comprising hydrogen and at least one C6-C20 paraffin;
- introducing at least one inert diluent selected from methane and nitrogen into the heavy paraffin feed;
- contacting the heavy paraffin feed and the inert diluent with a catalyst in the reactor under dehydrogenation reaction conditions;
- and
- removing an effluent stream from the reactor at an outlet;
- wherein the heavy paraffin feed has a ratio of hydrogen to heavy paraffin in a range of 0.1:1 to 10:1 on a molar basis and a ratio of inert diluent to paraffin in a range of about 0.1:1 to about 3.0:1 on a mole basis.
