Item type: Patente , Access status: Abierto , Use of a catalyst composition for the catalytic depolymerization of plastics waste(2020-05-12) Streiff, Stéphane; Piccinini, Marco; Corma Canós, Avelino; Mengual Cuquerella, Jesús; Departamento de Ingeniería Hidráulica y Medio Ambiente; Instituto Universitario Mixto de Tecnología Química; Escuela Politécnica Superior de Gandia[EN] Use of a catalyst composition comprising A ) a first component containing oxidic compounds comprising aluminum and silicon with a molar ratio of silicon to aluminum of more than 1 ) B ) a second component containing an oxidic compound of silicon wherein the ratio of the number of acidic sites of component A , determined by temperature programmed desorption with ammonia as a base , to the number of acidic sites of component B , determined under the same conditions , is at least 3 : in a process for the catalytic depolymerization of plastics waste.Item type: Patente , Access status: Abierto , Use of a catalyst composition for the catalytic depolymerization of plastics waste(2020-01-21) Streiff, Stéphane; Piccinini, Marco; Liebens, Armin T.; Corma Canós, Avelino; Cerro Alarcón, Miriam; Mengual Cuquerella, Jesús; Departamento de Ingeniería Hidráulica y Medio Ambiente; Instituto Universitario Mixto de Tecnología Química; Escuela Politécnica Superior de Gandia[EN] Patent relating to the use of a catalytic composition based on aluminum oxides or aluminum-silicon oxidic compounds, with an Al/Si molar ratio greater than 1, for the catalytic depolymerization of plastic waste. The invention falls within the field of chemical recycling of plastics through catalytic processes.Item type: Patente , Access status: Abierto , Process for converting waste plastic into liquid gases, fuels, and waxes by catalytic cracking(2020-02-26) Streif, Stéphane; Piccinini, Marco; Corma Canós, Avelino; Cerro-Alarcón, Miriam; Mengual Cuquerella, Jesús; Departamento de Ingeniería Hidráulica y Medio Ambiente; Instituto Universitario Mixto de Tecnología Química; Escuela Politécnica Superior de Gandia[EN] The present invention relates to a process for converting waste plastic into gases, liquid fuels and waxes by catalytic cracking. The process comprises the steps of introducing waste plastic and a catalyst within a reactor; allowing at least a portion of the waste plastic to be converted to gases, liquid fuels and waxes within the reactor; and removing a product stream containing said gases, liquid fuels and waxes from the reactor. In view of the increasing importance of polymes as substitutes for conventional materials of construction, such as glass, metal, paper, and wood, the perceived need to save on-enewable resorces such as petroleum and dwindling amounts of landfill capacity available for the disposal of waste products, considerable attention has been devoted in recent years to the problem of recovering, reclaiming, recycling or, in some way, reusing waste plastic.
