Chevron has been granted a patent for a process to produce renewable distillate-range hydrocarbons. The method involves dehydrating bio-based alcohols to create olefins, oligomerizing them with a halometallate ionic liquid catalyst, and hydrogenating the resulting oligomer product to yield renewable diesel fuel.

Renewable diesel fuel production process from bio-based alcohols
The granted patent US12043589B2 outlines a method for producing renewable diesel fuel from bio-based alcohols, specifically isobutanol. The process begins with the dehydration of these alcohols to generate an olefin stream and a water stream, achieving a conversion rate of 95% or more while ensuring that the olefin stream contains less than 1 weight percent of oxygenates. Following this, the olefin stream is separated from the water stream and then subjected to oligomerization using a halometallate ionic liquid catalyst. This catalyst, which consists of an organic cation and a halometallate anion, facilitates the formation of an oligomer product characterized by a specific composition of tri-substituted and tetra-substituted olefins, with a significant portion of the product having a boiling point distribution between 150°C and 400°C.
The patent further details the separation of the oligomer product from the catalyst and its subsequent fractionation to recover a diesel fuel fraction stream. This diesel fuel fraction is composed of 50 to 90 mol % of tri-substituted and tetra-substituted olefins and has a branching index ranging from 56 to 68. Additional claims specify that the diesel fuel fraction can be hydrogenated to meet or exceed the standards set by ASTM D975-21, either before or after fractionation. The claims also indicate that the final diesel fuel product may contain 60 to 80 mol % of the specified olefins, ensuring its suitability for use as a renewable diesel fuel.
