Abstract:Toaddressthecurrent issesof insuficientconditionsof thecontinuouscarbonizationexperimentalresearch platformsandthecomplexityofcarbonizationdevices,whichcannotmeettherequirementsforrapidandeficient biochar preparationprocess test,itisproposed touse the tuberesistance furnace biomass pyrolysiscarbonization technology combined with a non-axial screw conveying principle to integrate continuous pyrolysis technology.This appoach ensures uniformheating of biomassand improves processing efciency.a novel continuous biochar productiondevicewas designed.Keycomponents such as a tube resistance furnace,non-axial screw feeder,and a biochar collction box are designed.The temperatureconditionsof the pyrolysis carbonization processareadjusted bycontroling the temperatureof the tuberesistance furnace,andthedurationof the pyrolysis carbonization process ismodifiedbyadjusting therotation speedof the non-axial screw feeder.Asecond-order rotary orthogonal combinationexperiment was conducted by using soybean strawas theraw material for pyrolysis carbonization.The testresults demonstratedthatthe biochar production rate was 3.1kg/h ,thebiochar yieldwas 30.11% ,and the energy consumption was .When verification experiments were performed under the conditions of a carbonization temperature of 545∘c ,acarbonization time of 17 minutes,a raw material particle size of 1.6mm ,and a moisture content of 28% ,the specific surface area(Bet)and elemental content(C,N,H,S)were 6.30m2/g and 85.79% ,respectively,the error compared with the predicted values of and 85.89% was less than 1% .The fixed carbon content was 57.95% ,meeting the design requirementsandachievingrapidand eficientcontinuouspyrolysisofbiomass.Thisprovidesanexperimental platformfor the optimization of continuous biomass pyrolysis carbonization technology.
