Problems solved by technology

However, the catalyst loaded in an industrial reactor will be affected by temperature, reactant concentration, etc., and such model parameters given in the literature cannot be directly applied to industrial devices, so it is necessary to obtain a catalyst kinetic model suitable for actual industrial reactors Parameters, as well as the dynamic model parameters when the catalyst is deactivated, so as to deeply understand the reaction process, and then find the best industrial operating parameters, apply to the production process, optimize production, save energy and reduce emissions
