Renewable Diesel Process Overview

1. Feedstock Selection: The first step in making renewable diesel is selecting the appropriate feedstock. New Rise has chosen to use the cleanest of the various feedstocks by only using soybean and corn oil.

2. Pre-treatment: The feedstock is pre-treated through a ‘degumming’ process which removes phosphatides as well as any other any impurities such as trace metals. This is done to ensure that the final product is of high quality and meets the required specifications.

3. Hydrotreating: The pre-treated feedstock is then heated to high temperatures and mixed with hydrogen gas in the presence of a catalyst to undergo hydrotreating. This process involves breaking down the long-chain hydrocarbons in the feedstock into smaller molecules, which are then purified to create a cleaner fuel.

4. Fractionation: After hydrotreating, the mixture is then fractionated to separate the different components of the fuel based on their boiling points. This allows for the removal of any unwanted compounds and ensures that the final product meets the required specifications.

5. Hydrogenation: The final step in making renewable diesel involves hydrogenation, which is the process of adding hydrogen to the fuel to improve its properties. This is done to increase the cetane number of the fuel, which is a measure of its combustion quality, and to reduce the amount of pollutants emitted during combustion.
