Filed:

Nov 13, 2000

Appl. No.:

09/711576

Inventors:

Rusty M. Pittman - Chicago IL
Lawrence L. Upson - Barrington IL

Assignee:

UOP LLC - Des Plaines IL

International Classification:

C07C 406

US Classification:

585653, 585651, 585648, 585644, 585650, 208118, 208114, 2081201

Abstract:

An FCC process for obtaining light olefins comprises contacting a hydrocarbon feed stream with blended catalyst comprising regenerated catalyst and coked catalyst. The catalyst has a composition including a first component and a second component. The second component comprises a zeolite with no greater than medium pore size wherein the zeolite comprises at least 1 wt-% of the catalyst composition. The contacting occurs in a riser to crack hydrocarbons in the feed stream and obtain a cracked stream containing hydrocarbon products including light olefins and coked catalyst. The cracked stream is passed out of an end of the riser such that the hydrocarbon feed stream is in contact with the blended catalyst in the riser for less than or equal to 2 seconds on average.

UOP LLC - Des Plaines IL

International Classification:

B01J 808

US Classification:

422139, 422144, 422145

Abstract:

A high efficiency FCC process obtains the necessary regenerated catalyst temperature for a principally thermal cracking stage by cracking a light feedstock such as naphtha or a middle distillate in a first riser that principally performs thermal cracking and then cracks a heavy FCC feed in a second riser with a blend of catalyst from the principally thermal cracking step and recycle catalyst from the heavy feed to provide the necessary coke content on the catalyst that will produce high regenerated catalyst temperatures. The high temperature of the regenerated catalyst in the first riser provides a convenient means of cracking naphtha under high severity conditions and then using the remaining activity of the contacted catalyst for the principally catalytic reaction of the heavier feed. A separate thermal cracked product may be recovered from an intermediate blending vessel downstream of the first riser. Alternately, the thermal products such as cracked naphtha products may remain with the effluent from the second riser for separation from the heavy cracked products in a downstream separation zone.

The hydrocarbon products including light olefins are separated from the coked catalyst. The first portion of the coked catalyst is passed to a regeneration zone in which coke is combusted from the catalyst to produce a regenerated catalyst.

Assignee:

UOP LLC - Des Plaines IL

International Classification:

C10G 11/05

US Classification:

2081201, 208106, 208113, 208118, 208119, 502 67

Abstract:

Catalyst compositions comprising a siliceous zeolite component, either in separately formed catalyst particles or dispersed in the same binder or matrix as other zeolites of the compositions, are described. The catalyst compositions, for example as blends of three different bound zeolite catalysts, are particularly useful in fluid catalytic cracking (FCC) processes due to the reductions in coke and dry gas yields that allow FCC throughput, which is normally constrained by gas handling and/or catalyst regeneration capacity, to be increased.

Abstract:

One exemplary embodiment can be a fluid catalytic cracking system. Generally, the fluid catalytic cracking system includes a first reaction vessel and a second reaction vessel.
