The invention discloses a heavy oil modification system and a method for an acoustic cavitation synergic hydrogen donor, and aims to increase the content of a heavy oil light component, improve the flowability of heavy oil, alleviate the gathering and transportation and transferring difficulties and increase the light oil yield of heavy oil smelting processing. The heavy oil modification system consists of a hydrogen donor supply unit, a mixing unit and a plurality of acoustic cavitation processing unit, wherein the hydrogen donor supply unit is used for supplying a hydrogen donor and is connected with the input end of the mixing unit; the mixing unit is used for mixing the heavy oil and the hydrogen donor; the output end of the mixing unit is connected with the hydrogen donor supply unit; the acoustic cavitation processing unit is used for modifying the heavy oil. According to the components and the physical and chemical characteristics of the heavy oil, a proper amount of the hydrogen donor is added into the heavy oil, acoustic cavitation treatment on a mixed liquid of the heavy oil and the hydrogen donor is implemented in a sealed treatment container by using an ultrasonic transducer, viscosity detection, component analysis, boiling point distillation testing and molten product analysis are implemented on the heavy oil, the heavy oil modification effect of the acoustic cavitation synergic hydrogen donor can be evaluated, and optimal parameters of heavy oil modification can be obtained.

Description

technical field [0001] The present invention relates to a system and method for upgrading heavy oil by acoustic cavitation, more specifically, a system and method for upgrading heavy oil by acoustic cavitation and a hydrogen supply agent. Background technique [0002] Energy is the lifeblood of the national economy and the people's livelihood. Since the beginning of the 21st century, it has become an indisputable fact that the supply of crude oil has become heavy and inferior (high sulfur, high acid, high metal content, high residual carbon, etc.). Heavy oil mainly includes heavy oil, Natural heavy crude oil such as oil sands and residual oil produced during crude oil processing, according to statistics, the global reserves of heavy crude oil account for about 70% of the total oil reserves, and the output of residual oil is as high as 50% of the crude oil processing volume . In addition, the demand for clean vehicle fuels and low-carbon olefins is increasing, and environmen...
