  • Patent number: 11104970
    Abstract: The present invention discloses a method of preparing oligosaccharide using biomass sugar as raw material. The method places a biomass sugar in a quartz tubular reactor, places the quartz tubular reactor at a temperature-controlled zone of a tubular thermal conversion reactor under the protection of nitrogen gas, controls a thermal conversion time, rapidly quenches a material to obtain an oligosaccharide precursor after thermal conversion ends, then dissolves by adding pure water and purifies through an inorganic ultrafiltration membrane, and finally obtain an oligosaccharide after drying.
    Type: Grant
