  • Publication number: 20230357531
    Abstract: The invention relates to a process for depolymerizing a polyester feedstock comprising PET, said process comprising, prior to the step of depolymerization by glycolysis and to the step of purification of the depolymerization effluent, an improved step of conditioning the feedstock in which the polyester feedstock is conditioned in terms of temperature and pressure and then mixed with a diol effluent in a static or dynamic mixer in order in particular to substantially reduce the viscosity of the feedstock.
    Type: Application

  • Publication number: 20230035324
    Abstract: The invention relates to a process for depolymerizing a polyester feedstock comprising PET, said process comprising, prior to the step of depolymerization by glycolysis and to the step of purification of the depolymerization effluent, an improved step of conditioning the feedstock in which the polyester feedstock is conditioned in terms of temperature and pressure and then mixed at least with a recycled residue effluent and a diol effluent in particular in order to substantially reduce the viscosity of the feedstock.

  • Patent number: 10287238
    Abstract: A process for the nitrilation of a fatty acid or of a fatty acid ester, which is optionally unsaturated, by reacting the fatty acid or fatty acid ester with ammonia in a reactor operating continuously in the gas phase or in the mixed gas-liquid phase in a temperature range of from 180 to 400° C., in the presence of a solid catalyst comprising at least one metal oxide, the metal of which belongs to column 8 of the periodic table, as a mixture with at least one metal oxide chosen from aluminum oxides, zirconium oxides, niobium oxides, tantalum oxides and tin oxides, the metal oxide(s), the metal of which belongs to column 8, being present in a volume ratio of 0.1 to 0.6 relative to the volume of the mixture of all the oxides.

  • Patent number: 9957207
    Abstract: The present invention relates to a process for the selective hydrogenation of a feed of hydrocarbons containing polyunsaturated molecules comprising at least 3 carbon atoms, using a single principal fixed bed reactor R1 containing at least two catalytic beds A1 and A2 and a fixed bed guard reactor which is reduced in size, said hydrogenation reactors being disposed in series for use in a cyclic manner in accordance with a sequence of steps which can be used to short-circuit the catalytic bed or beds of the principal reactor which have been at least partially deactivated with the aid of the guard reactor, while ensuring the continuous operation of the process.
