摘要： The present invention relates to a process for the hydroconversion of mixtures of polymers or plastics which comprises the pre-treatment of the mixtures through methods selected from mechanical methods, chemical methods, thermal methods, or combinations thereof forming a pre-treated charge. The pre-treated charge is mixed with a hydrocarbon vacuum residue, optionally pre-heated, to form a reactant mixture. The reactant mixture is fed to a hydroconversion section in slurry phase, together with a catalyst precursor containing Molybdenum, and a stream containing hydrogen, forming a reaction effluent. The effluent is separated into at least one high-pressure and high-temperature separator in a vapour phase and a slurry phase. The separate vapour phase is sent to a gas treatment section with the function of separating a liquid fraction from the gas containing hydrogen and hydrocarbon gases having from 1 to 4 carbon atoms; said liquid fraction comprising naphtha, atmospheric gas oil (AGO), vacuum gas oil (VGO). The slurry phase is then sent to a separation section that has the function of separating the fractions of the Vacuum Gas Oil (VGO), Heavy Vacuum Gas Oil (HVGO), Light Vacuum Gas Oil (LVGO), Atmospheric Gas Oil (AGO), from a stream of heavy organic products which contains asphaltenes, unconverted charge, catalyst and solid formed during the hydroconversion reaction. This stream of heavy organic products is partly recirculated to the hydroconversion section and partly forms a purge stream.

摘要： The present invention relates to a catalyst comprising coke characterised in that said coke, upon analysis by infrared spectroscopy in diffuse reflection ("Diffuse Reflectance Infrared Fourier Transform Spectroscopy" - DRIFTS), has at least two peaks at a wavelength comprised between 1450 cm-1 and 1700 cm-1. The aforesaid catalyst comprising coke can be advantageously used in a process for the production of a diene, preferably a conjugated diene, more preferably 1,3-butadiene, said process comprising the dehydration of at least one alkenol having a number of carbon atoms greater than or equal to 4. Preferably, said alkenol having a number of carbon atoms greater than or equal to 4 can be obtained directly from biosynthetic processes, or through catalytic dehydration processes of at least one diol. When said alkenol is a butenol, said diol is preferably a butanediol, more preferably 1,3-butanediol, even more preferably bio-1, 3- butanediol, i.e. 1,3-butanediol deriving from biosynthetic processes. When said diol is 1,3-butanediol, or bio-1, 3-butanediol, the diene obtained with the process according to the present invention is, respectively, 1,3-butadiene, or bio-1, 3-butadiene.
