Shell Fiber Conversion Technology
Ethanol producers can increase margins by creating higher-value products with Shell Fiber Conversion Technology. They can also generate trading credits and renewable identification numbers (RINs) to comply with 鈥 and profit from 鈥 the renewable fuel standard (RFS) and state-level provisions such as California鈥檚 Low Carbon Fuel Standard (LCFS).
Shell Fiber Conversion Technology
Shell Fiber Conversion Technology is a bolt-on technology that enables producers of first-generation ethanol to significantly increase their profitability.
It converts lignocellulosic biomass, such as wet distillers grains (WDG) from corn ethanol plants, into enhanced-protein animal feeds, distillers corn oil (DCO) and cellulosic ethanol.
In addition, the Shell process uses a reusable acid, and the low-temperature operation is intrinsically non-fouling, which helps to reduce maintenance costs and improve the on-stream factor.
Shell鈥檚 Experience in Fuels and Biofuels
Shell is one of the world鈥檚 largest traders and blenders of . In 2019, we blended about 10 billion liters of biofuels, thereby helping retail customers decarbonize millions of journeys each year.
Benefits of Shell Fiber Conversion Technology
The technology enables corn ethanol producers to shift their product portfolio 鈥 making it both more valuable and more resilient. The process converts high fiber and relatively low-value products (WDG) into the following high-value streams:
- Enhanced-protein animal feeds, which command a higher sales value than the feeds produced by first-generation ethanol plants, and are in high, and growing, demand.
- DCO, which can be used as an advantaged feed for hydrotreated vegetable oil (HVO) units, including the Shell Renewable Refining Process. The technology can double the total DCO output of a dry mill.
- Cellulosic ethanol, generating D3 RINs.
In addition, the technology has been designed with a focus on achieving benchmark levels of operability, reliability, and energy efficiency.
