Embodiment Construction

[0021] The invention discloses a continuous reaction system for preparing bio-oil by hydrothermal liquefaction of microalgae. By setting two-stage preheaters, the waste heat after liquefaction reaction can be fully utilized, thereby reducing the overall energy consumption of the reaction system. In addition, the system can continuously and efficiently realize the separation of liquefied products through the joint action of solid-liquid separator, gas-liquid separator and centrifuge, without the need for additional organic solvents to separate bio-oil. Compared with other hydrothermal liquefaction systems, the system of the present invention has low operating cost, thorough product separation and good system continuity, and can be widely used in microalgae hydrothermal liquefaction to produce bio-oil.

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

Abstract

The invention provides a continuous reaction system for preparing bio-oil through microalgae hydrothermal liquidization and a method thereof. According to the invention, a two-stage preheater is set so that waste heat after liquidization can be fully used, and integral energy consumption of the reaction system is reduced. The system can continuously realize the separating of the liquidized products with high efficiency through combined effect of a solid-liquid separator, a gas-liquid separator and a centrifuge, and an extra organic solvent for separating the bio-oil is not required. Compared with the other hydrothermal liquidization systems, the system provided by the invention has the advantages of low operation cost, complete separation of the products, and good system continuity, and can be widely used for preparing bio-oil through microalgae hydrothermal liquidization.

Description

【Technical field】 [0001] The invention belongs to the field of biomass energy, and relates to a production technology of bio-oil, in particular to a continuous reaction system and method for producing bio-oil by hydrothermal liquefaction of microalgae. 【Background technique】 [0002] Microalgae hydrothermal liquefaction technology (referred to as HTL) refers to the use of thermochemical methods to convert microalgae raw materials into biological The process of substance oil. HTL is a very promising microalgae oil production technology with many advantages. First, compared with traditional thermochemical conversion technologies (such as gasification and pyrolysis), HTL can directly convert undried wet microalgae (water content 80-90wt%) into energy-dense biomass oil, thereby avoiding the Due to the additional high energy consumption in the drying process, it has a lower energy consumption rate and is especially suitable for processing wet biomass such as microalgae. Second...
