METHOD OF INITIATION OF CHAIN REACTIONS OF DISSOCIATION AND POLYCONDENSATION OF HYDROCARBONS AND A DEVICE FOR ITS REALIZATION Russian patent published in 2005 - IPC

FIELD: chemical industry; natural gas industry; petroleum industry; petrochemical industry and other industries.

SUBSTANCE: the invention falls into chemical industry, natural gas industry, petroleum industry, petrochemical industry and other branches pertaining to processing of hydrocarbon raw material, in particular, with production of a condensate consisting of light hydrocarbon gases and with processing of high-viscosity petroleum and petroleum residue. Substance of the invention: the method provides for a thermal treatment of the raw materials and treatment of a surface of a layer or a stream of a feed stock in a gaseous medium containing hydrogen and-or gaseous alkanes at a heightened temperature and an atmospheric pressure by ionizing radiation of relativistic electrons with energy in the range from about 0.5 up to about 10.0 MeV, preferably, from about 0.5 up to about 2.5 MeV at a width of the layer or a stream of a feed stock equal to the depth of sorption of the electronic emission, defined by the ratio λ x ρ = 0.5 E - 0.1, where λ - the depth of sorption of the electronic emission, cm; ρ - a density of the raw material, g /cm³; E - energy of electrons, MeV. Electrons irradiation is conducted onto the one side of the layer or from the two counter sides of the layer in the mode of a continuous irradiation or in a pulsed - periodic mode. The invention offers devices for realization of the method. The invention allows to increase output of the low-molecular hydrocarbons and to ensure a desirable productivity of the process.

EFFECT: the invention ensures an increased output of the low-molecular hydrocarbons and a desirable productivity of the process.
