Document Type and Number:
WIPO Patent Application WO/2022/142585
Kind Code:
A1
Abstract:
A method for rapidly evaluating the quality of a lignin pyrolysis bio-oil on the basis of free radical detection, and an application thereof. According to the method, the quality of a lignin pyrolysis bio-oil can be evaluated by measuring the spin content of free radicals in lignin char obtained by lignin pyrolysis, thereby avoiding complex processes of extraction, separation, and inspection involved in conventional quality evaluation of a pyrolysis bio-oil, and greatly reducing detection costs. The detection method is simple and easy to operate, and achieves the rapid evaluation of the quality of a lignin pyrolysis bio-oil. In addition, said method relates to non-contact detection, and samples are not destroyed, which is suitable for the rapid detection of the quality of a lignin pyrolysis bio-oil in industrial and scientific research fields, thus broadening the application field of free radical detection, promoting the development of free radical detection technology in the field of pyrolysis, providing a reliable method for inspecting a lignin pyrolysis bio-oil, and having good application prospects.
