Pyrolysis of microalgae: A critical review

The invention relates to a method for preparing a liquid product rich in furfural and other furan chemicals by biomass. The method comprises the following steps: a catalyst is added into particles of a biomass raw material by a dry method or a wet method; the mixture is dried after the mixture is sufficiently mixed; the mixture is placed in a drying cabinet to remove free moisture for standby; the obtained material is filled into a quartz reactor, the reactor is placed in a microwave purolyzer, and oxygen in the quartz reactor and a condenser pipeline is driven off by inert gas; and microwaveis started, power of the microwave is adjusted to pyrolyze the material in the quartz reactor, and the pyrolyzed steam is condensed into a pyrolysis liquid through a two stage water-cooled condenser.The method has the advantages that the yield of the pyrolysis liquid reaches over 50 percent (dry base), the furfural in a liquid product is over 60 percent of the content of organic compositions, which is far higher than the content of quickly pyrolzed furfural by the biomass (below 10 percent), and the time of a pyrolyzing reaction is obviously shortened. The method has the characteristics of simple process, single product, high furfural selectivity, and the like.
