Abstract: A process for thermal cracking of a feedstock of plastic materials, in particular waste materials, includes the steps of melting the feedstock, conveying melted feedstock in a pyrolysis chamber where the melted feedstock is heated in a substantially oxygen purged environment, to convert it into pyrolysis gases, the process further comprising the steps of: driving pyrolysis gases from the pyrolysis chamber into a tray reflux column comprising a partial condenser at its upper extremity, returning pyrolysis gases condensed in the tray reflux column into the pyrolysis chamber, distilling pyrolysis gases exiting the partial condenser of the reflux column, to provide one or more fuel products.
