There is a limited supply of fossil fuels so they are unsustainable as a source of energy and during combustion CO2 is produced which is considered a leading contributor of greenhouse gas. In order to address greenhouse gas production a carbon neutral form of fossil fuel can be produced from bio-waste products. The conversion process is hydrothermal liquefaction (HTL) which converts long chain carbon (organic) material into crude oil (shorter chain carbon) and purified water which is contained in the organic material. The purified water, a byproduct of the HTL process, is needed since clean water is becoming difficult to obtain. The current HTL process is a batch type process. Conversion from a batch process into a continuous process requires research and development to determine mixing ratios, heating time, and flow rates to optimize it as a continuous process for minimal heat input. This is the focus of this current research.
