the cracking of heavy oils in the installation of catalytic cracking in u043fu0441u0435u0432u0434u043eu043eu0436u0438u0436u0435u043du043du043eu043c layer

摘要

method of light hydrocarbons consisting of ethylene, propylene, gasoline u0431u0443u0442u0438u043bu0435u043du043eu0432 and improved the flow of raw heavy oil obtained from u0432u043du0435u0448u043d its source, thein an additional reactor with downward flow, which uses the composition of catalystwhat the fcc for cracking heavy oil and removing the reaction products flow from more light hydrocarbons from the reactor with downward flow and u0440u0435u0433u0435 u043du0435u0440u0430u0446u0438u0435u0439 catalyst in the same establishedu0432u043au0435 regeneration that is used for regeneration of spent catalyst from the fcc installation.the efficiency of extraction required more lung u043eu043bu0435u0444u0438u043du043eu0432u044bu0445 hydrocarbon peaks by restricting the flow of raw materials supplied to the reactor with the u043du0438u0441u0445u043eu0434u044fu0449 they flow of heavy oilwhich can be recycled with relatively stricter terms, with reduction of unwanted by-products.
