Abstract
The invention relates to a method for rapidly pyrolyzing waste mycelium, and belongs to the field of microorganism and new energy. The method comprises the steps of: drying the waste mycelium according to characteristics of the waste mycelium containing organic materials such as protein, fat and cellulose, adding with appropriate hole making agent for granulating, feeding into a pyrolysis reactor, rapidly pyrolyzing in a thermal reactor under an anoxic condition, controlling pyrolysis temperature and reaction time, generating pyrolysis coke, and multi-stage condensing the generated gas to below 100 DEG C in a condenser so as to obtain pyrolysis oil (containing oil phase and water phase) and non-condensable gas. The pyrolysis coke can be further processed into active carbon; and the pyrolysis oil is taken as chemical raw material or rectifying biological diesel oil. According to the invention, the pyrolysis method is used for treating the solid waste mycelium in biopharmaceutical industry, so that the reutilization, the minimization and the harmlessness of the waste mycelium can be effectively realized.
