Abstract
A hydrocarbon conversion process is disclosed. The process introduces a feed stream comprising hydrocarbons into a vessel having a refractory lining. The refractory lining comprises a refractory material and reinforcement metallic fibers. The reinforcement metallic fibers comprise about 0.5 wt % to about 8 wt % aluminum, 10 wt % to about 35 wt % chromium, and no less than about 50 wt % iron. The hydrocarbons are converted in the vessel at conversion conditions with or without a catalyst to yield a product stream.
Claims17
A hydrocarbon conversion process, comprising;
- introducing a feed stream comprising hydrocarbons into a vessel having a refractory lining, the refractory lining comprises:
- a refractory material;
- and
- reinforcement metallic fibers comprising about 0.5 wt % to about 8 wt % aluminum, about 10 wt % to about 35 wt % chromium, and no less than about 50 wt % iron;
- and
- processing the hydrocarbons in the vessel at conditions present in the vessel,
- wherein the refractory lining comprises about 1 wt % to about 10 wt % reinforcement metallic fibers.
A composite comprising:
- a refractory material comprising no more than about 3.5 wt % iron oxide and at least about 33 wt % aluminum oxides;
- and
- reinforcement metallic fibers comprising about 0.5 to about 8 wt % aluminum, 10 to about 35 wt % chromium and no less than about 50 wt % iron,
- wherein the refractory lining comprises about 1 wt % to about 10 wt % reinforcement metallic fibers.
An apparatus for processing hydrocarbons, comprising:
- a vessel having a refractory lining, the refractory lining comprises:
- a refractory material;
- and
- reinforcement metallic fibers comprising about 0.5 wt % to about 8 wt % aluminum, 10 wt % to about 35 wt % chromium, and more than about 50 wt % iron,
- wherein the refractory lining comprises about 1 wt % to about 10 wt % reinforcement metallic fibers.
