Embodiment 1

[0029] Using pine sawdust as raw material, crush it to less than 1mm, and follow the above steps for raw material preparation, charging, air venting and microwave cracking. The cracking time is 12 minutes, and the liquid product is collected. The liquid product yield is 26.0%, the furfural content is 50.0%, and the water content is 27.7%.

Embodiment 2

[0031] Using cotton stalk sawdust as raw material, the same steps as in Example 1 were adopted to collect the liquid product. The liquid product yield is 18.7%, the furfural content is 36.5%, and the moisture content is 33.2%.

Embodiment 3

[0033] Using Chinese fir sawdust as raw material, adopt the same steps as in Example 1 to collect the liquid product. The liquid product yield is 24.7%, the furfural content is 43.6%, and the water content is 28.4%.

Abstract

The microwave catalytic biomass cracking process for preparing biological oil with rich furfural features using ferric sulfate as catalyst, silicon carbide as microwave absorbing medium, microwave source as heat source for cracking biomass, and ice water mixture for cooling volatile component to obtain biological oil with rich furfural. The present invention can obtain liquid product with furfural content of 35-55 % and raise the utilization value of furfural greatly. The present invention uses solid ferric sulfate catalyst and is superior to acid hydrolysis process with corrosion and pollution problems.

Description

technical field [0001] The invention relates to a method for preparing organic chemical raw materials, that is, a method for preparing furfural-rich bio-oil from biomass. Background technique [0002] At present, energy and environmental issues have become the focus of global attention, and fossil fuel resources still play the role of the world's energy pillar and the source of bulk organic chemical products. While benefiting mankind, fossil fuels have also caused serious pollution to the environment on which human beings depend. Moreover, fossil fuels will be exhausted in the near future, and it is imperative to seek alternative resources. Biomass, as the only renewable energy that can be converted into liquid fuel, has become a global consensus to expand and optimize its utilization. The liquid fuel bio-oil converted from biomass cracking basically does not contain sulfur, nitrogen and metal components, and has no pollution to the environment. In addition to consideratio...
