Delayed coking process converts biomass to graphite at reduced temperatures and generates fuels

This article was originally posted on Chemical Engineering Online.
Summary
Researchers at the National Laboratory of the Rockies are adapting refinery delayed coking to convert biomass into synthetic graphite at lower temperatures, addressing rising U.S. demand for graphite in lithium-ion battery anodes and steelmaking. The process uses existing petroleum-refinery equipment to build a domestic supply (largely imported from China today) and also produces fuels.

What do you see as the biggest technical or economic hurdles to retrofitting refineries to produce biomass-derived graphite at scale?

Demand for synthetic graphite, a top-priority critical material in the U.S., is increasing because of its use in lithium-ion battery anodes and in steel-making. To meet the increased demand, while also cultivating a domestic source of synthetic graphite (most of which currently comes from China), a team of researchers at the National Laboratory of the Rockies is developing a process for making biomass-derived graphite that uses existing petroleum-refinery equipment and works at reduced temperatures compared to conventional graphite synthesis from needle coke.

Leveraging delayed cokers for biomass is intriguing; how are you controlling ash/alkali and chlorine so the product meets battery-grade specs on Na/K/Ca/S/Cl? Do you still require a high‑temp anneal or acid purification step to tighten d002/raise tap density, and have you tried co-coking with VGO/decant oil to tune microstructure and yields while keeping fuel streams on spec?
