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 such as wetcake, captive distillers corn oil (DCO) and low carbon intensity cellulosic ethanol.

In addition, the Shell process uses a reusable acid, which helps to cut operating costs, and the low-temperature operation is intrinsically non-fouling, which helps to reduce maintenance costs and improve the on-stream factor.

Shell’s Experience in Fuels and Biofuels

Shell is one of the world’s largest traders and blenders of biofuels. In 2019, we blended about 10 billion liters of biofuels, thereby helping retail customers decarbonize millions of journeys each year.

Through Raízen in Brazil, a joint venture with biofuels company Cosan, Shell is one of the world's largest sugarcane ethanol producers. If Raízen were a country, it would be the fifth largest producer of bioethanol in the world. In 2019, Raízen produced 2.5 billion liters of sugarcane ethanol.

Benefits of Shell Fiber Conversion Technology

The technology enables corn ethanol producers to shift their product portfolio – making it both more valuable and more resilient. The process converts high fiber and relatively low-value products (WDG, wetcake) 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.
  • Captive DCO, which can be used as an advantaged feed for hydrotreated vegetable oil (HVO) units. The technology can double the total DCO output of a dry mill.
  • Low carbon intensity 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.
