Embodiment 1
[0029] The method proposed by the present invention adopts figure 1 The shown fixed-bed pyrolysis furnace system mainly includes five parts: the fixed-bed pyrolysis furnace main body, feeder, temperature control system, nitrogen supply system and biological oil collection system. Among them: 1-main body of fixed-bed pyrolysis furnace; 2-feeder; 3-temperature control system; 4-nitrogen bottle; 5-flow meter; 6-condensation device; 7-water washing device; 8-wet flow meter. 1-The main body of the fixed-bed pyrolysis furnace is heated by the 3-temperature control system, and at the same time, the 4-nitrogen bottle is opened to pass in nitrogen, and the flow of nitrogen is controlled by a 5-flow meter. When the temperature of the pyrolysis furnace reaches the set temperature, the raw materials are fed into the fixed-bed pyrolysis furnace through the 2-feeder, and the pyrolysis reaction begins. The products produced by the pyrolysis pass through the 6-condensing device to obtain bio-o...
Embodiment 2
[0045] The system used in this embodiment is the same as that in Embodiment 1, and will not be repeated.
[0046] Among them, 2wt.% KCl is added to the acid hydrolysis residue of the pyrolysis raw material by dipping. The specific method is: weigh a certain amount of the acid hydrolysis residue after drying and crushing (same as Example 1), and calculate the acid hydrolysis residue. The 2wt.% mass of KCl powder reagent was completely dissolved in distilled water, and then the weighed acid hydrolysis residue was added to the solution, stirred at room temperature for 12 hours, and finally dried at 105°C for 24 hours as the treated acid hydrolysis residue.
[0047] This example uses figure 1 The fixed bed pyrolysis furnace system shown. In this implementation, the pyrolysis temperature is set to 650° C., and 200 g of the acid hydrolysis residue added with 2 wt.% KCl powder reagent is pyrolyzed. The specific implementation steps are as follows:

Embodiment 3
[0056] The system used in this embodiment is the same as that in Embodiment 1, and will not be repeated.
[0057] Among them, 5wt.% KCl is added to the acid hydrolysis residue of the pyrolysis raw material by dipping. The specific method is: weigh a certain amount of the acid hydrolysis residue after drying and crushing (same as Example 1), and calculate the acid hydrolysis residue. The 5wt.% mass of KCl powder reagent is completely dissolved in distilled water, and then the weighed acid hydrolysis residue is added to the solution, stirred at room temperature for 15 hours, and finally dried at 110°C for 24 hours as the treated acid hydrolysis residue.
[0058] This example uses figure 1 The fixed bed pyrolysis furnace system shown. In this implementation, the pyrolysis temperature is set to 700°C, and 200 g of the acid hydrolysis residue added with 5 wt.% KCl powder reagent is pyrolyzed. The specific implementation steps are as follows:
[0059] (1) Open the fixed-bed pyrolysis fu...
