Abstract
The present invention is a process for thermal cracking and reforming of a liquid petroleum stream comprising the liquid petroleum fraction, wherein the liquid petroleum fraction is a substantial portion of the first liquid petroleum stream and has a density equal to or less than about 15° API.
Claims18
A process for a first liquid petroleum fraction for reducing the specific gravity thereof comprising:
- (a) a first liquid petroleum stream comprising the first liquid petroleum fraction, wherein the first liquid petroleum fraction is a substantial portion of the first liquid petroleum stream and has a density equal to or less than about 15° API;
- (b) introducing the first liquid petroleum stream into convective heating means for heating the first liquid petroleum stream substantially only by convective heat transfer from a hot gas and out of the presence of a catalyst to less than an average liquid temperature of about 1000° F.;
- and
- (c) obtaining a substantially thermally cracked stream from the heating means.

- (a) a first liquid petroleum stream comprising the first liquid petroleum fraction, wherein the first liquid petroleum fraction is a substantial portion of the first liquid petroleum stream and has a density equal to or less than about 15° API;
- (b) introducing the first liquid petroleum stream into heating means for heating the first liquid petroleum stream in conduits and out of the presence of a catalyst for a period of less than about 25 seconds to less than an average liquid temperature of about 1000° F.;
- (c) stopping the flow of the first petroleum stream to the heating means and flowing steam at high velocity through the conduits for a period of less than about 25 seconds;
- (c) repeating steps (b) and (c) to obtain a thermally cracked stream and a reformed stream, respectively, from the heating means.
