Providing Breakthrough Feedstock Solutions for Fuel Producers

Comstock Fuels’ patented process converts lignocellulosic biomass into easy to use, deoxygenated feedstock for fuel producers to produce carbon-neutral, Short-Cycle Biofuels.


It’s The Feedstock:
Goodbye Long-Cycle Carbon

The path to very low or no-carbon biofuels has been constrained by insufficient and unsustainable feedstocks.

And when it comes to woody biomass, the challenge has been efficiently converting its carbon-consuming and storing value into a cost-effective, plentiful stream of feedstock that is free from contaminants, and which can easily, reliably, and sustainably be used in today’s existing, downstream hydrotreating and fuel production infrastructure (refineries).

Comstock Fuels has met that challenge with our proven, patented, high-yield process that nets 100 gasoline equivalent gallons or more from one tonne of lignocellulosic biomass. At commercial scale.


Short-Cycle Biofuels:
Making Decarbonization of Fuels Possible and Profitable

By breaking through the technical challenges of converting woody biomass, we unlocked the value of millions of tonnes of unused and underused waste wood, Kraft lignin, and new, sustainably grown lignocellulosic fuel crops to provide a sufficient, plentiful supply stream of high yield short-cycle Biofuel feedstock to existing and future renewable fuel refineries.

is the breakthrough.

Bioleum™ is a proprietary, unique blend of deoxygenated hydrocarbons that is suitable for hydroprocessing, resulting in more than 100 gallons of low-carbon biofuels per tonne of biomass on a gasoline gallon equivalent energy basis.
