Bio-Propane

Basics

• Difficult to do from a methane upgrading route, but this paper shows it is possible
• The paper used a Chromium-Zinc Catalyst on a β-Zeolite Catalyst, which is luckily not too rare (ie no rare earth metals etc)

• EForFuel
  • A Project using P2X Technology and Formic Acid Fed Precision Fermentation to make Bio-Butane, with a goal of usage as Autogas
• DME / DME Blending / DME-Propane Blending
  • While NOT the same, the similar storage conditions have lead some propane groups to propose blending DME into the propane as a means to reduce the Carbon Intensity of the fuel
• Propane Storage Architecture

• Alkconn - Biopropane - ‘’Proprietary’’ Catalytic Methane->Propane Conversion
• An Article by “FGE Nextant” Titled “The problem with on-purpose bio-propane“
  • While largely critical, it did show a good summary of the current state of the art/economics of that
  • Also mentioned the Low Carbon Fuel Standard or LCFS / Carbon Pricing and what impact that may have
  • TLDR: Propane is largely popular due to it being a cheap byproduct
    • Compared to High Value and/or High Volume options like SAF etc, propane is low priority and low profitability (without heavy carbon taxing)
      • They did mention Oberon Fuels / rDME or DME blending in Propane, DME-Propane Fuel Blends , which was neat!
