Preliminary Studies on the Purification of Bleaching Earth from Slack Wax Residues in the Adsorption Refining by Low-Temperature Pyrolysis Process

Abstract The essence of the low-temperature pyrolysis process presented below is the processing of contaminated bleaching earth, resulting in a purified bleaching earth, high calorific oil with an average level of 45.5 MJ / kg and synthesis gas that can be used to heat the reactor. For research purposes, a proprietary low-pressure reactor with a system of direct cooling of hydrocarbon vapors was used. The main advantages of the presented method are the limitation of technological processes to a minimum and the ease of automation by reducing the entire cycle to one device.
