Other methods for producing vinyl chloride from dichloroethane
Thread Content
I read some literature on vinyl chloride production methods and found that in the ethylene-based approach, the cracking of dichloroethane is carried out through thermal cracking, under high temperature and pressure, with low conversion rates. I wonder why no one has studied catalytic cracking for this purpose Is it feasible? Please give your advice
Upstairs, the low pyrolysis rate is intended to prevent or prolong the time before coking occurs in the furnace tubes; if the pyrolysis rate is too high, coking takes place more quickly. Currently, the process requires that the pyrolysis rate be controlled at 55%; if this rate is not properly controlled, it becomes difficult to manage the distillation tower during the subsequent separation of components. The three components—hydrogen chloride, vinyl chloride, and dichloroethane—are separated in the hydrogen chloride tower; the middle components, vinyl chloride and dichloroethane, are separated in the vinyl chloride tower, with dichloroethane being recycled back into the reaction process.
Well, thanks to the person on floor 2. I know the reasons for the low conversion rate; I mainly want to know if there are any other processes Has catalytic cracking been studied? I couldn’t find it in the literature. Thank you
