Abstract

The invention discloses a high-pressure cooling-heating table device for in-situ observation of an aquo-complex microscopic reaction kinetics process. The high-pressure cooling-heating table device comprises a high-pressure cooling-heating table body, an observation system, a gas supply system, a gas discharge system, a temperature control system, a pressure control system and a computer data acquisition system, wherein a cooling channel connected with the temperature control system and used for controlling the temperature in a reaction tank is also arranged inside a base; the high-pressure cooling-heating table body further comprises a gas inlet and a gas outlet communicated with the reaction tank; the gas supply system and the gas discharge system are respectively communicated with the gas inlet and the gas outlet of the high-pressure cooling-heating table body, and are used for providing high-pressure gas for the high-pressure cooling-heating table body. The high-pressure cooling-heating table device for the in-situ observation of the aquo-complex microscopic reaction kinetics process has the beneficial effects that the observation on gas hydrate through laser Raman under a high pressure environment is realized; the allowable pressure is large; high-pressure buffer tanks are respectively arranged at the gas inlet end and the gas outlet end of the high-pressure cooling-heating table body, so that the pressure and the gas flow velocity inside the high-pressure cooling-heating table can be effectively controlled.

Description

technical field [0001] The invention relates to a high-pressure cold and hot stage device for in-situ observation of the microscopic reaction kinetic process of hydrates and a method for using the same. Background technique [0002] Gas hydrate is an ice-like crystal formed by gas molecules and water molecules under low temperature and high pressure conditions. Naturally formed gas hydrates are widely distributed in plateau permafrost and sediment layers of shallow sea continental shelves. In recent years, with the discovery of a large number of natural gas hydrates around the world, it has become an important alternative energy source and has attracted the attention of countries all over the world. At the same time, 1 standard volume of gas hydrate can store up to 160 standard volumes of gas, and the temperature and pressure conditions required for storage are milder than those of liquefied gas, so it can be widely used in natural gas storage and transportation, and the fi...

AI Technical Summary

Problems solved by technology

This method cannot truly simulate the actual high-pressure reaction process of hydrates

Moreover, limited by the size and design of the test bench, only a small part of the hydrate sample generated in the reactor can only be taken out, and it cannot be taken out as a whole
