Biocrude

Basics

• A viscous liquid resembling crude petrolium oil in most respects
• Produced from biomass
• Can be aquired from a variety of methods (see HTL )
• Some forms of Pyrolysis Oil can be considered Bio-Crude, but their compositions are not as broad in most cases (research needed on this)

Used For

• Burning as a fuel Itself
• Refining it into Bio-Petrochemicals and other derivatives (Biofuels such as Bio Gasoline, Biodiesel, etc) using a Biorefinery and/or Biocrude Refinery

Catalyst Compatibility

"Raw"

• Supposedly has some issues with Catalyst Poisoning

Processing Methods Which Help

• Could maybe use "sweetening" as a name for this, this is used for sulfur removal in-industry?
• "Review of Denitrogenation of Algae Biocrude Produced by Hydrothermal Liquefaction"
• "Metals and Other Elements in Biocrude from Fast and Isothermal Hydrothermal Liquefaction of Microalgae" (May fit better in composition?, it only is talking about contaminants that could foul catalysts however, not specific hydrocarbons)

Composition

• Get papers on typical chemical composition + ratios of each
• This is so we can calculate the typical "flows" of a Biorefinery / Bio-Crude Refinery 's Fractional Distilation Column
• [http://e2-energy.illinois.edu/Characterization%20of%20bio-crude%20oil.pdf "Chemical properties of biocrude oil from the hydrothermal liquefaction

of Spirulina algae, swine manure, and digested anaerobic sludge" ] Given how it used sludge / Black Water it may not be the best from a biofuels application/perspective?

• • Quote: "Molecular weights tracked with obdurate carbohydrate content and followed the order of Spirulina < swine manure < digested sludge"
