Problems solved by technology

However, the use of gas-phase discharge requires the liquid raw material of crude oil to be heated and vaporized first, and most of the energy is used for heating instead of generating plasma, which consumes a lot of energy, and the density of the working gas is small, resulting in low plasma density, resulting in hydrogenation of heavy oil Low efficiency, low yield of light liquid
In addition, gas phase discharge in heavy oil is also prone to carbon deposition, and the generated carbon will be attached to the electrode, which will affect the discharge, thereby affecting the efficiency of lightening heavy oil

Abstract

The invention discloses a method and device for upgrading heavy oil raw materials by utilizing liquid-phase discharge in-situ hydrogenation. The method comprises the steps that discharge is directly performed in a liquid, liquid-phase discharge hydrogen production is combined with liquid-phase discharge hydrogenation for upgrading heavy oil, a hydrogen production raw material is added into the heavy oil raw materials in a high electric field region of a reactor, liquid-phase high-pressure discharge plasma is utilized to simultaneously decompose the hydrogen production raw material and heavy oil molecules in different regions, active hydrogen free radicals are generated from the hydrogen production raw material in a plasma strong field region to rapidly react with the heavy oil molecules cracked by liquid-phase discharge, correspondingly hydrogen production, cracking of the heavy oil raw materials and in-situ hydrogenation are simultaneously carried out, and therefore the weight reduction of heavy oil is realized. The method has the advantages that in-situ hydrogen production and hydrogenation are realized, the reaction efficiency is high, and the weight reduction rate is effectively increased. Meanwhile, the device can be directly used for fuel oil modification in online application, and liquid and gas products generated by the device can be used as fuels for combustion withoutseparation.

Description
