The invention discloses a device and a method for preparing bio-based aldehydes and ketones. The device comprises an NTP catalysis-regeneration reaction system II; the NTP catalysis-regeneration reaction system II comprises a catalytic reactor, a spiral combustor, an NTP generator and an oxygen supply device; the spiral combustor and the NTP generator are arranged outside the catalytic reactor; and the oxygen supply device is connected with the catalytic reactor and the spiral combustor. The method for preparing the bio-based aldehydes and ketones through self-heating NTP online catalysis-regeneration is achieved through the device, the used catalyst generates high-energy particles through NTP and carbon deposits on the active substance oxidation catalyst, the catalyst is regenerated, theregeneration temperature is low, the structure of the catalyst is kept intact, and the catalyst can be repeatedly used. 一种制备生物基醛酮类的装置与方法，包括NTP催化-再生反应系统II，NTP催化-再生反应系统II包括催化反应器、螺旋燃烧器、NTP发生器和氧气供给装置，催化反应器外部设有螺旋燃烧器和NTP发生器，所述氧气供给装
