    摘要: A process for converting liquid or semi-liquid hydrocarbon charges to lighter fractions comprises a first step (a) heating droplets jets of the charge introduced into a pyrolysis chamber by surrounding them with parallel jets of hot solid particles, of relatively large size, of a heat carrier material, not substantially in contact with the droplet jets, so as to maintain a temperature of 700.degree.-1600.degree. C., and introducing a gas so as to obtain a pressure from 1 to 150 bars. A second step involves (b) separating the gaseous fraction from the solid particles. Thereafter (c) at least a portion of the solid particles are heated and fed back to step (a). The gaseous fraction is (d) cooled by means of a cold gas so as to recover light hydrocarbons therefrom.

    摘要: A co-current cyclone mixer-separator which makes it possible to separae a light phase L1 contained in a mixture M1 which also contains a dense phase D1 from the dense phase and to mix this phase L1 with a dense phase or with a mixture containing this phase and a light phase. The mixture M1 is introduced at and the phase D1 is recovered at. The dense phase of a mixture is introduced at and enters a second inner enclosure at, at least a part of the phase likewise entering the latter enclosure. A mixture comprising the phases, if it has been introduced, is obtained at. Preferably, the apparatus comprises blades which make it possible to limit the progress of the vortex into the outlet. This apparatus permits of a rapid heat exchange, for exmple the hardening, of a phase by a phase or a mixture. It can also be used for the rapid replacement of a phase contained in a mixture also containing a phase by a phase other than.
