selectivity, but the cost is high and the yield is low. Microwave-assisted extraction
has the disadvantages that the extraction yield is low for each time and is not suitable for amplification for the process research. The high-pressure and low-polarity
water extraction method requires high-performance equipment and that is not easy
to achieve. In sum, choosing a safe, fast, and economical extraction process has a
significant research value.
10.7 Comprehensive Utilization of Processed Woody Oil
Plant Residues in Our Research Group
Aiming at the technical bottlenecks, namely low utilization rate of the industrial
woody oil plants, backwardness of the processing technology and equipment, weakness of unitary and low value-added products, the research team groups the woody oil
plant residues into remaining oil, proteins, saponins, and fibers, and looks to achieve
high-valued utilization among all resources. The whole-chain structured layout and
integrated design are carried out from three dimensions as the basic research innovation, the key technology breakthrough, and the regional integrated demonstration.
By breaking through with a number of steering technologies and focusing on creating core technologies of independent intellectual property rights, the all-resources
utilization rate of processed woody oil plant residues is targeted from 20 to 80%.
The overall value of the industry aims to be increased by 30%.
First, by developing poly-generation technology of the non-oil component
inverted to fertilizer and energy, the utilization rate of oil residue resources can
be increased by over 20%. The production technology of bio-organic fertilizer with
natural active source has been innovated, and multifunctional bio-organic fertilizer
that is eligible for fertilizer feeding, soil improving, and pest controlling has been produced. Four bacteria strains, which are capable of antagonizing plant pathogens and
easily degrading the crude protein of tung tree meals into water-soluble amino acids,
are isolated and screened with independent intellectual property rights. By means
of strain purification, refinement, rejuvenation, and cultivation expansion, a bacteria
agent for rapid fermentation and maturing can be prepared (Fig. 10.1). Single-factor
test and response surface method are adopted to optimize the solid-state fermentation conditions of the combined strains. The optimal processing parameters of fermentation duration, fermentation temperature, material proportion, etc., have been
determined to produce a multifunctional bio-organic fertilizer that is competitive in
fertilizing, soil improving, and pest controlling. The total content of free amino is
43.9 times higher than that before fermentation. The product meets the requirements
of the bio-organic fertilizer standard (NY 884-2012), and three invention patents
have been applied.
Second, the technology of preparing briquette fuel by coupling, drying, and molding the oil plants and forest processing residues has been developed. It is made clear
that three oil plants processed residues (husk, dregs, and bio-asphalt, additive amount
