Abstract: The present invention discloses a rapid evaluation method for quality of lignin-pyrolyzed bio-oil and an application thereof, and particularly relates to a rapid evaluation method for quality of lignin-pyrolyzed bio-oil based on radical detection and an application thereof. The method can be used to evaluate the quality of lignin-pyrolyzed bio-oil by detecting the spin concentration of radicals in lignin char obtained by lignin pyrolysis, thus avoiding the complex processes involved in the evaluation for the quality of conventional pyrolyzed bio-oils such as, extraction, separation and detection and reducing the detection costs substantially. The detection method of the present invention is simple and easy to operate, thus achieving the rapid evaluation for the quality of lignin-pyrolyzed bio-oil. Moreover, the detection method of the present invention is non-contact detection without destructive samples, which is applicable to the rapid detection on the quality of lignin-pyrolyzed bio-oil in the field of industry and scientific research. The present invention further broadens the application fields of radical detection and contributes to the development of radical detection technology in the field of pyrolysis, and provides a reliable method for the detection of lignin-pyrolyzed bio-oil, which has good application prospect.

Abstract: The present disclosure relates to a pyrolysis bio-oil fractional condensation device and method capable of cooling medium self-circulation. The device includes a primary condensation system, a secondary condensation system and a cooling medium self-regulation heat exchange system. The primary condensation system uses the temperature-regulated cooling medium to condense the macromolecular tar by direct heat exchange with the pyrolysis volatiles. The condensed tar is heated, pushed and scraped with a rotary mechanism to prevent adhesion. The spray liquid in the secondary condensation system exchange heat with the uncondensed volatiles directly for secondary condensation. The cooling medium self-regulation heat exchange system realizes self-circulation and self-balance of the cooling medium mass flow and energy flow by integrating heat absorption during biomass raw material feeding and drying, heat release during volatiles condensation, and heat absorption during pyrolysis char cooling, and realized the independent operation of the condensation device in the mobile biomass pyrolysis system.

Abstract: The provided is energy storage method and device for biomass cascade pyrolysis coupled with new energy power generation. The key point of the technical solution is that, with inexpensive, clean and safe biomass as energy storage medium, the redundant unstable electric energy is converted by a cascade pyrolysis energy storage system into an easy-to-store liquid and solid chemical energy in biomass pyrolytic products, and based on use requirements, can be further converted into clean fuels for power generation or exported renewable chemicals, so as to realize continuous stable output of the new energy power generation systems. Furthermore, the cascade pyrolysis energy storage system can, based on the principle of “energy level matching”, fully recover and utilize the electric energy, high-temperature heat energy and low-temperature heat energy generated in pyrolysis processes, thereby maximizing the energy utilization efficiency of the system.
