Problems solved by technology

[0013] The purpose of the present invention is to provide a heavy oil processing reaction evaluation device, which has Less sample consumption, fast reaction temperature rise, reliable evaluation data, simple device structure, low investment and operation costs, and suitable for solid-containing reaction systems, etc.
[0014] After in-depth research, the inventors of the present invention found that the existing heavy oil processing reaction evaluation device has a complex structure, is not convenient enough to operate, and has high investment and operation costs. It has a great influence on the reaction results, a long experiment cycle and a relatively single function, and is not suitable for multi-phase reaction systems (such as solid-containing slurry phase reaction systems)

Abstract

The invention relates to the field of heavy oil and model compound reaction evaluation thereof, and discloses a heavy oil processing reaction evaluation device. The heavy oil processing reaction evaluation device comprises a driving unit, a reactor (5), a temperature measurement reactor (6) and a heating element (9), wherein the driving unit is used for driving the reactor (5) and the temperature measurement reactor (6) to synchronously enter and exit the heating element (9); a first temperature measurement element (2) is arranged on the temperature measurement reactor (6); and the first temperature measurement element (2) is used for detecting the temperature in the temperature measurement reactor (6). The heavy oil processing reaction evaluation device is low in sample consumption, reliable in evaluation effect and simple to operate, and is capable of effectively reducing the operation cost so as to eliminate the influences, on the reaction result, of the preheating process and satisfy the reaction requirements of the multi-phase reaction systems.

Description

technical field [0001] The invention relates to a reaction evaluation process of heavy oil and its model compounds, in particular to a heavy oil processing reaction evaluation device. Background technique [0002] The availability of conventional oil is decreasing day by day, but the total amount of heavy oil resources in the world is huge, so heavy oil will become an important energy source in the 21st century. How to convert these growing heavy oils and a large amount of residual oil has become a major issue in the refining industry today. [0003] my country's heavy oil processing technology is basically a decarbonization process, mainly distillate oil catalytic cracking, thermal cracking, solvent deasphalting, delayed coking, etc. [0004] Distillate oil catalytic cracking is currently the most important means for heavy oil processing in my country to increase the yield of light oil. The raw materials are mainly straight-run vacuum distillate and a small amount of coker...
