Problems solved by technology

However, the components of bio-oil obtained by pyrolysis technology are extremely complex, and the disadvantages such as low pH value, high oxygen content, poor thermal stability, and high viscosity make bio-oil difficult to be directly used and stored.
In addition, the post-treatment process of bio-oil is complicated, the effect is not good, and the cost is high, making it difficult for industrial application

specific Embodiment

[0067] The pine sawdust was processed by a self-dusting biomass pyrolysis and cracking system, and the basic data of the raw materials are shown in Table 1.

[0068] Table 1: Basic data of pine wood chips

[0069]

[0070] Using this reaction system to process pine wood chips, the yield of gas products obtained is 65%, and the pyrolysis tar is almost completely cracked into gaseous products, with a high gas yield. The dust content in the pyrolysis gas produced by the system is less than 1%, and the gas is relatively clean.

[0071] In the description of the present invention, it should be understood that the terms "first" and "second" are used for description purposes only, and cannot be interpreted as indicating or implying relative importance or implicitly indicating the quantity of indicated technical features. Thus, a feature defined as "first" and "second" may explicitly or implicitly include one or more of these features.

Description

technical field [0001] The invention belongs to the technical field of biomass pyrolysis, and mainly relates to a self-dusting biomass pyrolysis and cracking system based on heat storage radiant tube heating to produce clean combustible gas. Background technique [0002] Biomass energy is the fourth largest resource on earth and also the renewable energy with the largest reserves. Biomass has the characteristics of wide distribution, abundant reserves, renewable and low pollution, and is one of the most potential alternative energy sources for fossil energy. At present, the energy utilization of biomass energy is mainly based on fermentation to produce fuel, biogas, gasification, rapid pyrolysis, and carbonization. Among them, the production of fuel and biogas by fermentation mainly uses herbal plants. The disadvantages of this technology, such as long production cycle and low yield, limit its development; gasification technology for gas production is mostly used in power g...
