Abstract

The invention discloses a fibrin transforming laevoglucose device. A nitrogen gas interface, which connects to high purification nitrogen gas through fluid bed pre-heating unit, is connected in the bottom of quartz glass cell. A filter is set in the horizontal branch of the reactor, and the outlet connects to multi-step condensing unit. The top of the quartz glass cell reactor is set a sealed cover. The material inlet of the up sealed cover is set a pothook used to fill cylinder material, and the silicon carbon tube is set outside the quartz glass cell. And the two ends of the silicon carbon tube are cool ends that connect to power supply. One end of the thermocouple connects to the heating zone in the middle of the silicon carbon tube, and the other end connects to control panel. Asbestos blanket is set outside the silicon carbon tube. Under the best reaction condition, the output of laevoglucose could reach 54.5%.

Description

technical field [0001] The invention relates to a device for converting cellulose into levoglucose. Background technique [0002] With the rapid and continuous development of the world economy, the consumption of fossil energy is increasing year by year, and the available oil reserves are becoming less and less. The oil crisis generally plagues countries all over the world. However, most of the raw materials of the chemical industry that modern civilization relies on come from oil industry. Faced with the problem of oil shortage, people are gradually turning their attention to other alternatives, such as biomass, which is considered to be one of the powerful alternatives to replace oil to produce fuels and chemicals. [0003] Biomass is the most extensive renewable resource in the world. Its development and utilization meet the requirements of human beings for the sustainable development of environmental protection resources. At present, it has been highly valued by countri...
