Abstract: A method having the following steps: subjecting plastic waste material to a thermal pre-treatment in order to produce a liquid plastic mass, wherein the thermal pre-treatment of the plastic material is carried out in an inert gas atmosphere at a temperature that varies between 110° C. and 310° C.; simultaneously feeding the liquid plastic mass to a reaction apparatus; bringing the plastic mass into contact with a bed of particles of inorganic porous material contained inside the reaction apparatus at a temperature of between 300° and 600° C.; inducing thermocatalytic decomposition reactions at a temperature of between 300 and 600° C. in order to generate a mixture of hydrocarbons in a vapor phase; and separating the hydrocarbons from the vapor phase current generated inside the reaction means in order to produce a liquid mixture of hydrocarbons.

Abstract: The invention relates to a method for producing hydrocarbons by catalytic decomposition of plastic waste products in a single step, said method comprising: subjecting the plastic waste material to a thermal pre-treatment in order to produce a liquid plastic mass, wherein the thermal pre-treatment of the plastic material is carried out in an inert gas atmosphere at a temperature that varies between 110° C. and 310° C.; simultaneously feeding the liquid plastic mass to a reaction apparatus; bringing the plastic mass into contact with a bed of particles of inorganic porous material contained inside the reaction apparatus at a temperature of between 300° and 600° C.; inducing thermocatalytic decomposition reactions at a temperature of between 300 and 600° C. in order to generate a mixture of hydrocarbons in a vapour phase; and separating the hydrocarbons from the vapour phase current generated inside the reaction means in order to produce a liquid mixture of hydrocarbons.
