Embodiment Construction
[0034] The micro-fluid discharge conversion reactor has a double-tube structure, the outer tube is plexiglass, the discharge structure is a wire-tube type, the high-voltage electrode is a stainless steel threaded rod, the thread diameter is 5mm, and the length is 500mm. The inner tube is a quartz glass tube as a barrier medium Layer, with a layer of aluminum foil attached as a ground electrode. The specific operation steps are as follows:
[0035] (1) Preheat the plasma conversion reactor to 80 o C, preheated hot water steam generator;
[0036] (2) Crush the corn stalks and grind them into a particle size of 0.2 mm. Use a sieve to add the sieved straw powder into the funnel of the screw feeder, and connect it with nitrogen as the secondary feeding gas;
[0037] (3) Before the discharge reaction, purge the reactor with nitrogen for 5 minutes to remove the air in the reactor, and adjust the intake flow rate of discharge gas nitrogen to 5L / min;
[0038] (4) Add saturated water...

Abstract
The invention relates to a method for preparing a biofuel by converting straws with discharge plasma, which uses abundant renewable resources lignocellulose biomass straws on earth as the reaction raw material. Under the conditions of micro-streamer discharge plasma, tetrahydronaphthalene is carried to convert the straw biomass into the biofuel in an inert gas-water vapor environment. The method does not use acids, alkalis or any other high-corrosivity chemical substances and harmful radiation sources thereof in the reaction process, and thus, has the advantages of no pollution, no harm to the human body and no corrosivity to equipment in the reaction process. The whole technical process and product thereof are environment-friendly, and can effectively enhance the conversion rate of the straws and the quality of the biofuel in the discharge environment.
Description
technical field [0001] The invention belongs to the technical field of biofuel preparation, and in particular relates to a method for preparing biofuel by transforming straw with discharge plasma. Background technique [0002] Biomass is an abundant renewable resource on the earth. It is a variety of organisms produced through photosynthesis using the atmosphere, water, and land. It is all living and growing organic substances. It is different from traditional petroleum, coal, and nuclear energy. Fuel is a renewable energy substance. The use of biomass conversion to produce biofuel can alleviate the energy crisis and is conducive to environmental protection. Biofuel refers to solid, liquid or gaseous fuel converted from biomass, which can replace gasoline and diesel produced from petroleum, and is an important direction for the development and utilization of renewable energy. Since the 1970s, affected by traditional energy prices, environmental protection and global climate...
