METHOD AND EQUIPMENT FOR PRODUCING HYDROCARBONS BY CATALYTIC DECOMPOSITION OF PLASTIC WASTE PRODUCTS IN A SINGLE STEP

摘要

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 notions at a temperature of between 300 and 600° C in order to generate a micture 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. The invention also relates to equipment for producing hydrocarbons by catalytic decomposition of plastic waste products in a single step, comprising: apparatus for thermally treating the plastic waste material in order to produce a liquid plastic mass; apparatus for carrying out the catalytic decomposition of the liquid plastic mass and producing a mixture of hydrocarbons in a vapour phase; and apparatus for separating the hydrocarbons with between 5 and 44 carbon atoms front the vapour phase current generated inside the apparatus which carries out the catalytic decomposition in order to produce a liquid mixture of hydrocarbons.
