Embodiment 1

[0016] Example 1: Preparation of pyrolysis oil high in 1,6-anhydro-β-D-glucopyranose (abbreviation: inner ether sugar) by pyrolyzing corn stalks using the pyrolysis device shown in Figure 1

[0017] Put the crushed corn stalks into the reactor, connect the reactor with the cooler, and make the whole system well sealed, turn on the vacuum pump, and after the system reaches the maximum vacuum, quickly push it into the preheated (450°C) furnace , After reacting for 60 minutes, stop heating, separate the heating furnace from the reactor, after the reactor cools down, open the vent valve, turn off the vacuum pump, remove the collection bottle, and collect the pyrolysis oil. The yield of the pyrolysis oil accounts for about 70% (weight ratio) of the raw material, and the content of the inner ether sugar in the pyrolysis oil is about 25% (weight ratio), which can be further refined to obtain the inner ether sugar. The charcoal in the reactor is collected by unloading the reactor, and...

Embodiment 2

[0018] Example 2: Using the pyrolysis device shown in accompanying drawing 1 to pyrolyze sawdust to prepare pyrolysis oil with high inner ether sugar content

[0019] Put the sawdust into the reactor, connect the reactor with the cooler, and make the whole system well sealed, turn on the vacuum pump, and after the system reaches the maximum vacuum, quickly push it into the preheated (450°C) furnace, and react for 70 After 10 minutes, stop heating to separate the heating furnace from the reactor. After the reactor cools down, open the vent valve, turn off the vacuum pump, remove the collection bottle, and collect the pyrolysis oil. The yield of the pyrolysis oil accounts for about 60% (weight ratio) of the raw material, and the content of the inner ether sugar in the pyrolysis oil is about 20% (weight ratio), which can be further refined to obtain the inner ether sugar. The charcoal in the reactor is collected by unloading the reactor, and the productive rate of charcoal accoun...

Embodiment 3

[0020] Example 3: Using the pyrolysis device shown in accompanying drawing 1 to pyrolyze waste cotton to prepare pyrolysis oil with high content of endo-ether sugar

[0021] Add waste cotton into the reactor to seal the reactor and the cooler, and make the whole system well sealed, turn on the vacuum pump, after reaching the maximum vacuum, quickly push it into the preheated (450°C) furnace, and react for 60 minutes Finally, stop heating and separate the heating furnace from the reactor. After the reactor cools down, open the vent valve, turn off the vacuum pump, remove the collection bottle, and collect the pyrolysis oil. The yield of the pyrolysis oil accounts for about 70% (weight ratio) of the raw material, and the content of the inner ether sugar in the pyrolysis oil is about 65% (weight ratio), which can be further refined to obtain the inner ether sugar. The charcoal in the reactor is collected by unloading the reactor, and the productive rate of the charcoal accounts f...

Abstract

The invention relates to a biomass pyrolysis hydraulic device and a method for preparing pyrolysis oil by pyrolysis transforming biomass, and pertains to the technical field for using biomass resource. The purpose of the invention is to provide a device for preparing high-quality biomass pyrolysis oil, and a method using the device for preparing pyrolysis oil containing 1, 6-dehydrated-beta-D-glucopyranose. The pyrolysis oil prepared by the method is useful for extracting chemicals with high added values in the oil or makes easier the further modification treatment so that the oil can be used as an energy. The invention is technically characterized in that, a flat reactor and a heating furnace with proper size are used, the heating area is big, the heat-transferring efficiency is high, and high vacuum and rapid cooling are used, so that the pyrolysis product will not be liable to secondary dissolution, and the pyrolysis product is easy to be purified and refined. The reactor is additionally featured by the easy manufacturing and operation, and the wide application.

Description

technical field [0001] The invention belongs to the technical field of biomass resource utilization, and relates to a biomass pyrolysis liquefaction device and a method for pyrolyzing and transforming biomass to prepare pyrolysis oil. technical background [0002] Biomass pyrolysis refers to the rapid heating and cooling of biomass in the presence of very little oxygen, so as to obtain bio-oil (pyrolysis liquid), charcoal and non-condensable gas. Among them, the pyrolysis solution mainly contains hundreds of organic compounds such as phenols, alcohols, acids, aldehydes, sugars, and aromatics. The utilization of pyrolysis liquid is mainly used to extract high value-added chemicals (such as 1,6-β-sydrolide glucose), and to substitute diesel oil and gasoline after modification and treatment. At present, several types of equipment are available for this reaction, such as the carried-bed reactor developed by GIT of Georgia Institute of Technology in the United States, and the ro...
