Problems solved by technology

Now commonly used are steam cracking, catalyst cracking and hydrocracking: steam cracking is limited to relatively small molecules (generally less than 11 carbon atoms) as starting materials, which are used to make olefins; a large part of the raw materials in catalyst cracking are The catalyst sticks away, and a lot of carbon dioxide will be released during the catalyst regeneration process; hydrocracking cannot fully crack all the carbon-hydrogen compounds such as pitch, and the preparation of hydrogen will not only increase the cost, but also release carbon dioxide

Embodiment 1

[0035] The specific technological process that the method that the mixture involved in the present embodiment chemically reacts in the supercritical state carries out the cracking treatment to the heavy oil is as follows:

[0036] First, the heavy oil (semi-solid pitch) and water are mechanically mixed by the raw material input system 2 according to the volume ratio of 1:1.6 to form a suspension fluid mixture and injected into the reaction vessel 1;

[0037] Then, start the electrode system 3 pre-placed in the reaction vessel 1 to heat and pressurize the fluid mixture. The electrode system 3 includes 5 electrodes, which are arranged in a circle and discharge in sequence. The discharge interval between adjacent electrodes is 2 seconds, and each discharge is 80 milliseconds, until the monitoring system 4 monitors that the fluid mixture reaches a supercritical state, and the heavy oil and water molecules are fully mixed;

[0038] Finally, after the fluid mixture reaches the super...

Embodiment 2

[0041] The specific technological process that the mixture involved in the present embodiment is chemically reacted in a supercritical state to separate and crack the oil sand is as follows:

Description

Technical field: [0001] The invention belongs to the technical field of chemical reaction, and relates to a method for chemical reaction of a mixture in a supercritical state and its application. Background technique: [0002] The main components of petroleum or crude oil are compounds composed of carbon atoms and hydrogen atoms, and the number of carbon atoms determines the size of the molecule and the state under normal temperature and pressure. For example, methane, ethane, and propane molecules have 1, 2, and 3 carbon atoms, respectively, and are the smallest molecules among all hydrocarbon-hydrogen compounds. They are gaseous at room temperature and pressure; gasoline molecules have 8 carbon atoms, and diesel The molecule has 16 carbon atoms, and it is in a liquid state at normal temperature and pressure. With the further increase of the number of carbon atoms in the molecule, when it exceeds 20, the hydrocarbon-hydrogen compound gradually becomes a solid state at norm...
