Abstract
An internal circulation catalytic reactor includes a body extending along a longitudinal axis Z and defining an internal chamber, a catalyst bed located within the internal chamber, the catalyst bed being configured to hold a catalyst, an inlet fluidly connected to the catalyst bed and configured to receive a feed, an outlet fluidly connected to the catalyst bed and configured to discharge a product generated by an interaction of the feed and the catalyst, and an impeller fluidly connected to the catalyst bed and configured to circulate the feed through the catalyst bed. The impeller is configured to discharge a recirculate feed at a non-zero angle relative to a horizontal radial axis R.

An internal circulation catalytic reactor comprising:
- a body extending along a longitudinal axis Z and defining an internal chamber;
- a catalyst bed located within the internal chamber, the catalyst bed being configured to hold a catalyst;
- an inlet fluidly connected to the catalyst bed and configured to receive a feed;
- an outlet fluidly connected to the catalyst bed and configured to discharge a product generated by an interaction of the feed and the catalyst;
- and
- an impeller fluidly connected to the catalyst bed and configured to circulate the feed through the catalyst bed,
- wherein the impeller is configured to discharge a recirculate feed at a non-zero angle relative to a horizontal radial axis R.
An impeller for an internal circulation catalytic reactor, the impeller comprising:
- an impeller body;
- a top curved plate attached to the impeller body, the top curved plate having a proximal end that extends radially from the impeller body, and having a distal end that extends along a direction that makes a non-zero angle with the radial axis R;
- and
- a bottom inclined plate that defines with the top curve plate a rotational zone in which a feed is rotated.
A method for selecting a catalyst with an internal circulation catalytic reactor, the method comprising:
- loading a catalyst into a catalyst bed, which is located within an internal chamber of the reactor;
- injecting a feed at an inlet of the reactor, the inlet being fluidly connected to the catalyst bed;
- circulating the feed through the catalyst bed with an impeller which is fluidly connected to the catalyst bed;
- discharging at an outlet a product that results from an interaction of the catalyst with the feed;
- and
- recirculating a remainder of the feed through the catalyst bed with the impeller,
- wherein the impeller is configured to discharge the recirculated feed at a non-zero angle relative to a horizontal radial axis R.
