A method and apparatus for the continuous recycling of hydrocarbon containing used and waste materials such as plastic and polymeric waste including, for example, polyurethane, rubber wastes and the like, and in particular scrap rubber tires, are disclosed. The process is carried out under moderate temperatures and atmospheric pressure in the presence of air and a feed of liquid(s) containing oxygen. The method is characterized by the low residence time.

Method and apparatus for continuous decomposing waste polymeric materials

This invention relates to a process for removing polarizable impurities from hydrocarbons and mixtures of hydrocarbons using ionic liquids as an extraction medium. By way of extraction, the degree of contamination of the hydrocarbon or mixture of hydrocarbons is reduced to a low or very low level. The specific ionic liquids are compounds of the Formula 1, which are organic salts that are liquid or can be melted to form a liquid and that can form at least a biphasic mixture with a hydrocarbon. The process is suitable for purifying a wide range of hydrocarbons under a wide range of process conditions.
