Description

technical field [0001] The invention relates to a visualization experiment device, in particular to a visualization experiment device for researching the properties of hydrogen hydrate. Background technique [0002] Energy is the cornerstone of human society. With social development and population growth, human demand for energy will increase. Fossil energy represented by coal, oil, natural gas, etc. is currently the main energy source. However, fossil energy is a non-renewable resource, and its reserves on the earth are limited, and the extensive use of fossil energy has caused more and more serious environmental pollution problems. Therefore, the pressure of sustainable development forces humans to look for cleaner new energy sources, such as hydrogen energy. Hydrogen energy has many advantages, such as: the product of hydrogen combustion and energy release is water, without any pollution, and is a clean energy source; hydrogen has a wide range of sources, which can be ...
