  • Patent number: 9884304
    Abstract: An immersion fixed bed reactor intensified by liquid flow contains a cylindrical tank internally installed with an annular cylindrical catalyst bed (ACCB) packed with solid catalysts is provided. The inner and outer walls of the ACCB are composed of two layers of stainless steel sheets with holes. The outer layer of stainless steel perforated with holes. The inner layer of catalyst contacting stainless steel is covered with stainless steel waved mesh in circumferential direction. The bottom of AACB is sealed with a steel plate by welding or a blind plate and the top of ACCB is fixed to cylindrical tank with a flange. The solid catalysts are packed in the ACCB.

  • Patent number: 9308468
    Abstract: A process of integrated system formed by coupling of fixed bed, jetting floating bed, and separating unit, aimed to provide a new process and equipment of higher efficiency, which integrates multi-type reactors and separation is provided. Reaction materials undergo preliminary reaction in fixed bed reactor and intensified reaction in jetting floating bed reactor, and then separation in the subsequent separation system. Unreacted materials will be returned to the raw material intermediate storage tank for mixing with fresh materials, as raw materials for continued reaction. During this process, materials first pass the fixed bed reactor once to achieve certain conversion rate, and then enter the jetting floating bed reactor for intensified reaction. When the product reaches required concentration, the materials will enter subsequent separation equipment for separation.
