PROCESS FOR CONVERTING OLEFINS TO JET FUEL WITH DEALKANIZER - A simplified explanation of the abstract

This abstract first appeared for US patent application 18417244 titled 'PROCESS FOR CONVERTING OLEFINS TO JET FUEL WITH DEALKANIZER

Simplified Explanation: This patent application describes a process for converting olefins into distillate fuels through a two-stage oligomerization process.

Recycle olefin stream is combined with charge olefin streams in a first-stage reactor to produce a first-stage oligomerate.
The first-stage oligomerate is further processed in a second-stage reactor to obtain a second-stage oligomerate stream.
A recycle olefin stream is extracted from the second-stage oligomerate stream to improve efficiency.
A dealkanizer column may be utilized to remove light alkanes that could accumulate in the recycle loop.
The second-stage oligomerate stream is hydrogenated to yield distillate fuels.

Key Features and Innovation:

Two-stage oligomerization process for converting olefins into distillate fuels.
Recycling of olefin streams to enhance efficiency.
Use of a dealkanizer column to remove light alkanes.
Hydrogenation of the oligomerate stream to produce high-quality fuels.

Potential Applications:

Production of distillate fuels from olefins.
Petrochemical industry for fuel production.

Problems Solved:

Efficient conversion of olefins into valuable distillate fuels.
Removal of light alkanes to prevent accumulation in the process loop.

Benefits:

Increased efficiency in fuel production.
High-quality distillate fuels.
Reduced waste and byproducts.

Commercial Applications: The technology can be applied in the petrochemical industry for the production of high-quality distillate fuels, catering to the growing demand for clean and efficient energy sources.

Questions about Olefin Oligomerization: 1. How does the two-stage oligomerization process improve the conversion of olefins into distillate fuels? 2. What are the key advantages of using a dealkanizer column in this process?

Original Abstract Submitted

A process for oligomerizing olefins to distillate fuels which oligomerizes a recycle olefin stream with charge olefin streams in a first-stage oligomerization reactor. The first-stage oligomerate is oligomerized in a second-stage oligomerization reactor to provide a second-stage oligomerate stream. A recycle olefin stream is taken from said second-stage oligomerate stream. A dealkanizer column can be used to remove light alkanes that would be inert and accumulate in a recycle loop. The second-stage oligomer product stream is hydrogenated to produce fuels.
