电石法生产VCM的原理是将精制清净后的乙炔气与HCl，在氯化汞/活性炭

The principle of VCM production by calcium carbide method is to directly synthesize VCM by adding purified acetylene gas and HCl under the action of mercury chloride/activated carbon as a catalyst under normal pressure. <br>Acetylene gas and HCl are mixed and preheated according to the proportion, and enter the tubular reactor containing the catalyst of mercury chloride/activated carbon (HgCl2 content is generally 10.5%~12.5% ​​of the mass of activated carbon of the carrier), and the reaction produces crude VCM. The reaction heat is cooled and removed by the circulating water outside the reactor tube, so that the temperature in the reactor is maintained at 180°C.

The principle of the production of VCM by electrostone method is that the refined and clean acetylene gas and HCl, under the action of mercury chloride/activated carbon as catalyst, under normal pressure, a bonus reaction occurs, directly synthetic VCM.<br>Acetylene gas and HCl are mixed and preheated proportionally into a column-tube reactor containing mercury chloride/activated carbon (HgCl2 content is generally 10.5% to 12.5% of carrier activated carbon mass) catalyst, and the reaction produces a crude VCM. The reaction heat is removed by the cooling of circulating water outside the reactor tube, keeping the temperature inside the reactor within 180 degrees C.

The principle of producing VCM by calcium carbide method is to directly synthesize VCM by addition reaction of purified acetylene gas and HCl under atmospheric pressure with mercuric chloride / activated carbon as catalyst.<br>Acetylene gas and HCl are mixed and preheated in proportion, and then enter a tubular reactor with mercuric chloride / activated carbon (the content of HgCl2 is generally 10.5% ~ 12.5% of the mass of supported activated carbon) catalyst to produce crude VCM. The reaction heat is removed by circulating water outside the reactor tube to keep the temperature in the reactor within 180 ℃.<br>
