Abstract
An embodiment of the invention includes a riser reactor for reacting a feedstock and catalyst. The riser reactor wall defines an interior. A continuous refractory lining is attached to the reactor wall and defines a plurality of flow disruptors that extend inward from the wall into the reactor interior and disrupt flow patterns of the feedstock and catalyst.
Claims20
A riser reactor for reacting a feedstock and catalyst, the reactor comprising:
- a riser reactor wall defining an interior;
- a continuous refractory lining on the reactor wall, the refractory lining defining a plurality of flow disruptors that extend inward into the reactor interior and disrupt flow patterns of the feedstock and catalyst.
A riser reactor for reacting a feedstock and catalyst, the reactor comprising:
- a generally cylindrical riser reactor having an interior side wall and an interior;
- a mesh attached to the reactor side wall in at least first sections of the wall;
- refractory material cast about the mesh to form a lining on the reactor wall in the first sections;
- a plurality of flow disruptors formed by the refractory lining and mesh in the first sections, the flow disruptors extending inward from the wall into the reactor interior and configured to disrupt flow patterns of the feedstock and catalyst;
- and,
- refractory material cast onto the side wall in second sections of the wall, the refractory material in the second sections continuous with the refractory material in the first sections.

A riser reactor for reacting a feedstock and catalyst, the reactor comprising:
- a generally cylindrical riser reactor having a side wall and an interior that extends from a lower entrance to an upper exit;
- a refractory lining covering at least a portion of the sidewall between the reactor entrance and exit and surrounding the interior;
- the lining defining a plurality of first sections that have an interior surface that is substantially coextensive with the sidewall;
- the lining defining a plurality of flow disruptors arranged between and continuous with the lining first sections, the flow disruptors having an interior surface that extends inward into the interior relative to the first section interior surface, the flow disruptors shaped to disrupt flow patterns of the feedstock and catalyst;
- each of the lining flow disruptors comprising:
- a metal mesh attached to the reactor wall that surrounds the interior, the mesh comprising a repeating pattern of open cells, passages connecting at least some of the open cells to adjacent open cells;
- a plurality of standoff rods connecting at least some of the open cells to the side wall;
- and,
- refractory material cast about the mesh and filling the open cells and passages and enveloping the standoff rods, forming a lining on the reactor wall.
