Thermal fractionation of biomass of non-lignocellulosic origin for multiple high-quality biofuels

A method of pyrolytic thermal fractionation of microalgae biomass comprising a protein component and a triglyceride component with or without an additional carbohydrate component, the method comprising:

• (a) heating the microalgae biomass to a first volatilization temperature of a first component comprising at least one of proteins or carbohydrates, and holding the first volatilization temperature of the heated microalgae biomass constant for a first period of time until no further mass loss of the first component occurs, thereby producing a first volatilized vapor product derived from proteins and/or carbohydrates, wherein the first volatilization temperature is in the range of from 180° C. to 360° C.;
• (b) removing and recovering the first volatilized vapor product from the microalgae biomass remaining from step (a);
• (c) heating the microalgae biomass remaining from step (b) to a second volatilization temperature of a second component comprising triglycerides, and holding the second volatilization temperature of the heated microalgae biomass constant for a second period of time until no further mass loss of the second component occurs, thereby producing a second volatilized vapor product derived from the triglycerides, wherein the second volatilization temperature is in the range of from 370° C. to 500° C.;
• and
• (d) removing and recovering the second volatilized vapor product from the microalgae biomass remaining from step (c).
