The present disclosure relates to a catalytic reactor for cracking wax of pyrolysis oil generated from waste plastic pyrolysis emulsification process, a catalytic composition and a production method thereof. Particularly, the present disclosure relates to a catalytic composition for cracking wax, including: a support that includes zeolite containing silicon oxide and aluminum oxide, and silica; and an active metal that includes iron and zinc, and is immersed in the support, thereby cracking carbides with C14 or more included in wax of pyrolysis oil generated during waste plastic emulsification process.

A large circulating fluidized bed cell bioreactor and a method for culturing animal cells. The reactor comprises an agitator tank body (01), an agitator tank base (50), a water inlet silicone hose (06), a backflow silicone hose (08), a cell culture tank (10), a culture tank base (40), a backflow pipe (15), a water inlet pipe (12), an agitator (20), a reactor tray (30), and a tube support plate (60). By means of cooperation among the above components, defects and shortcomings of fluidized bed cell bioreactors in the prior art including proneness to microbial contamination, a low level of dissolved oxygen, and a low working volume, are effectively resolved, advantageous in the popularization and application of this technology.

An oxidative methane coupling (OCM) reactor has a reactor vessel that defines a reactor vessel interior. The reactor vessel having opposite ends and a central longitudinal axis that extends between the opposite ends. A catalyst bed assembly is positioned within the reactor vessel interior having a catalyst bed containing a layer of OCM catalyst of a uniform thickness. The catalyst bed assembly divides the reactor vessel interior into an upstream zone and a downstream zone. The catalyst bed has an upstream face for receiving the one or more flowing feed gases of methane and oxygen gas as a flowing mixture from the upstream zone. The upstream face of the catalyst bed is configured to have a total area that exceeds the largest transverse cross-sectional area of the interior of the reactor vessel that is perpendicular to the central longitudinal axis of the reactor vessel. The catalyst bed assembly is configured so that any portion of the flowing mixture passes from the upstream zone to the downstream zone through a single catalyst bed of the catalyst bed assembly.
