Design of catalyst and process for the dewaxing of petroleum oils Original Research Article

The influence of zeolite characteristics, feed properties and process parameters on the dewaxing of petroleum oils are reported. Specifically, the influence of the zeolite properties and process parameters on the quality and yield of the dewaxed products and the deactivation rate of the catalyst are discussed. A typical example of upgrading a paraffinic feedstock into a refrigeration grade oil is presented.
