Abstract

The present invention relates to a method for recovering soil from microalgae through pyrolysis, and more particularly, to a method for recovering only that soil which is easy to convert into fuel through two-phase pyrolysis, and comprising the steps of: a first pyrolysis phase of pyrolyzing a microalgae biomass at a temperature of 200 to 400°C to remove sugars and proteins; and a second pyrolysis phase of pyrolyzing the product of the first phase, from which the sugars and proteins have been removed, at a temperature of 450 to 700°C.
