Reactor and method commonly applicable for high-pressure in-situ DSC and neutron tests of gas hydrate

A reactor commonly applicable for high-pressure in-situ differential scanning calorimetry (DSC) and neutron tests of a gas hydrate, comprising:

• an adaptation section of high-pressure in-situ DSC test, comprising:
• a reactor body having a reactor raised neck at a bottom, wherein an upper end of the reactor body is provided with a reactor sealing unit and a reactor heating jacket, and the reactor heating jacket is installed during a neutron test and configured to maintain the reactor at a set temperature, so as to carry out a kinetic generation and decomposition experiment of the gas hydrate;
• a DSC test end cavity sealing unit arranged above the reactor body and provided with a quick connector;
• and
• a second gas intake pipe having a first end connected to an upper end of the reactor sealing unit and a second end extending through the DSC test end cavity sealing unit, wherein a gas enters the reactor body through the second gas intake pipe, thereby providing a material for generation of the gas hydrate and pressurizing the reactor;
• a metal thermal insulator is arranged on the second gas intake pipe between the reactor body and the DSC test end cavity sealing unit;
• the second gas intake pipe passes through a center of an end face of the metal thermal insulator;
• a plurality of polyvinyl fluoride thermal insulating sheets are distributed above the metal thermal insulator;
• and the second gas intake pipe passes through centers of the plurality of polyvinyl fluoride thermal insulating sheets;
• and during the neutron test, a neutron stopper is arranged between two polyvinyl fluoride thermal insulating sheets of the plurality of polyvinyl fluoride thermal insulating sheets;
• and
• an adaptation section of neutron test, installed above the adaptation section of high-pressure in-situ DSC test by the quick connector during the neutron test and comprising:
• a quick coupling flange configured to play a fixing role in the neutron test;
• and
• a first gas intake pipe passing through a center of the quick coupling flange.
