The candle combustion product iscarbon dioxideAnd water (gas).Soda lime can effectively absorb these two substances.The manufacturing method of this absorption device is as follows:
(1) Cut a section of glass tube with a length of 10 cm and a diameter of about 25 mm (it can be cut with a large tube with broken bottom).
(2) Install the metal mesh.Cut a round mesh with a diameter slightly larger than the inner diameter of the glass tube from the worn asbestos mesh, and gently push it in from one end of the glass tube, so that the round mesh is supported at about 2 cm from the pipe orifice as a mesh grid for placing alkali lime (if the mesh grid is easy to slide off, you can use a paper clip to change it into a ring with elasticity, and snap it tightly on the inner wall of the glass tube as a retaining ring to prevent the mesh grid from sliding off).
(3) Add alkali lime to make absorber.Large particles shall be selected for alkali lime to ensure gas circulation.The thickness of alkali lime layer is about 4-5cm.
(4) The experiment can be carried out by fixing the absorber directly above the candle on the left pan of the balance.
(5) The key to the success of this experiment is whether the candle burns normally and whether the generated gas passes through the absorber smoothly.Therefore, the size of the candle flame and the distance between the absorber and the flame should be tested in advance.If the experiment is normal, there will be obvious phenomenon in three minutes.The balance should preferably be a physical balance with a sensitivity of 0.02 g.

A device that uses the method of forming a product in a reaction chamber for at least two kinds of reactants, and the pressure of the product in the reaction chamber is lower than the pressure of each of the reactants to produce power. The device comprises: (a) at least one pipeline, connecting the source point of each of the reactants to the reaction chamber;And (b) at least one thermal engine is placed on at least one of the pipelines, and the reactants are arranged in the reaction chamber, so that the pressure in the reaction chamber is reduced by means of the reaction of the reactants in the reaction chamber, so that a pressure drop is generated across the at least one thermal engine.
Carbon disulfide treatment

edit
Generated from low-grade hydrocarbon and sulfurcarbon disulfideThe separation and treatment method of reaction products in the process includes the separation of excess and residual sulfur and the separation of hydrogen sulfide, which is characterized in that the sulfur in the reaction products is condensed and liquefied under the condition that all the pressure of the reaction system is borrowed to separate and remove,The remaining mixed gas will liquefy carbon disulfide and realize phase separation from hydrogen sulfide which is still a gas under the condition of keeping the borrowing pressure of 1.5-10 kg/cm2 and the temperature of - 10 -+20 ℃.
