High-temperature and high-pressure supercritical carbon dioxide reaction kettle

Abstract

The invention provides a high-temperature and high-pressure supercritical carbon dioxide reaction kettle. The reaction kettle comprises a reaction kettle device, a stirring device, a supercritical carbon dioxide generation system, a temperature control system and an emptying system. The reaction kettle can be used for testing under the simultaneous action of high-temperature and high-pressure conditions for a long time, the reaction state of reaction materials and supercritical carbon dioxide under different temperatures and pressures is simulated, and a monitoring system can be used for monitoring, controlling and recording the conditions such as the temperature and the pressure when the supercritical carbon dioxide reacts with the reaction materials in real time. The reaction kettle is sealed in a vertical sealing mode, so the sealing effect is better, and the sealing performance of the reaction kettle under high-temperature and high-pressure conditions can be ensured; and the reaction kettle is high in automation degree, so the temperature and pressure conditions in the reaction process are monitored in time, and the reaction process can be conducted efficiently, thereby the reaction mechanism of supercritical carbon dioxide and reaction materials can be researched and analyzed more comprehensively.

Description

technical field [0001] The invention relates to the technical field of reactor devices, in particular to a high-temperature, high-pressure supercritical carbon dioxide reactor. Background technique [0002] With the rapid development of the economy, people's awareness of environmental protection is gradually increasing, and a huge change is taking place in the type of energy use. As a greenhouse gas, carbon dioxide is in a supercritical state when the temperature is greater than 31.5°C and the pressure is greater than 7.38MPa. Supercritical carbon dioxide has the diffusivity of a gas, the solubility and density of a liquid, and also has the characteristics of low surface tension and low viscosity. Practice has proved that under the condition of high temperature and high pressure supercritical carbon dioxide, the reaction materials will have distinctive reaction effects. [0003] The high-temperature and high-pressure reactor is a common high-temperature and high-pressure te...
