Biomass oil low-temperature catalytic hydrodeoxygenation reaction system and method thereof

Abstract

The invention discloses a biomass oil low-temperature catalytic hydrodeoxygenation reaction system and a method thereof, the biomass oil low-temperature catalytic hydrodeoxygenation reaction system comprises a raw material supply module, a magnetic atmosphere module and an ultrasonic catalysis module, and the raw material supply module comprises an oil supply device and an air supply device; the ultrasonic catalysis module comprises an ultrasonic reaction device, a catalyst supply device, a rotary feeding shaft and a reaction pipe installed on the rotary feeding shaft. Biomass oil, diesel oiland hydrogen are mixed, and a mixed gas-liquid mixture enters the magnetic atmosphere module to be subjected to a magnetization viscosity reduction reaction, so that the dissolved hydrogen amount in the mixer is increased; the gas-liquid mixture and a catalyst flow into a reaction tube through a rotary feeding shaft, the reaction tube rotates along with the rotary feeding shaft, and the ultrasonicreaction device emits ultrasonic waves to the reaction tube, so that the mixed oil is cavitated, and the catalytic hydrogenation reaction of the biomass oil can be realized without high temperature and high pressure.

Description

technical field [0001] The invention relates to a biomass oil low-temperature catalytic hydrodeoxygenation reaction system and method in the technical field of new energy. Background technique [0002] With the recovery and development of the economies of various countries, the demand for energy in the world has greatly increased, and the reserves and recoverable reserves of non-renewable resources such as coal, oil and natural gas have been greatly reduced. In addition, the unrestrained development and use have brought about the increase of carbon dioxide greenhouse gases. The greenhouse effect caused by it, the formation of acid rain and other serious negative effects. Biomass energy in new energy is a form of energy in which solar energy is stored in biomass in the form of chemical energy, that is, energy that uses biomass as a carrier. It is directly or indirectly derived from the photosynthesis of green plants, and can be converted into solid, liquid and gaseous fuels....
