Cat-HTR’s Competitive Advantages
We believe the relative technological advantages of the Cat-HTR process for biomass can therefore be summarised as follows:
  • Lower carbon footprint due to a relatively low reaction temperatures (~ 300 degrees C) unlike other upgrading technologies such as pyrolysis (~500 degrees C) and gasification (~700 degrees C)
  • No need to dry biomass prior to processing – eliminating a step and reducing the cost of upgrading
  • Does not rely on external enzymes, uses water as a cost-effective catalyst
  • No external hydrogen required (reduces cost of production)
  • Higher yields: use all the biomass, 30 – 40% yield, 2+ bbls per odt feedstock
  • Not tied to one market – able to process any form of ligno-cellulosic material to produce range of finished products
  • Produces biofuels low in sulphur
  • Ability to mix feedstocks – greater project scale potential, lower production costs
  • One step process to a stable high energy biocrude oil
  • Uses all of the components of the biomass, unlike sugar hydrolysis
  • Certain minerals in the biomass are beneficial to the process by acting as catalysts
  • Primary product, biocrude, has low residual oxygen content
  • Low to no residual ash to contaminate the process (feedstock dependent).
  • The biocrude is readily upgradable to gasoline, diesel, kerosene and fuel oil blendstocks under mild conventional petrochemical processing conditions when co-processed with petroleum fractions.
  • High process thermal efficiency
  • Biocrude is not strongly acidic like pyrolysis oils
