摘要

describes the way to obtain u0431u0443u0442u0430u0434u0438u0435u043du0430 of n - butane with the following steps: a) preparation of a gas flow containing n - butane; b) food by gas adequate flow and containing n - butane, at least one first u0434u0435u0433u0438u0434u0440u0438u0440u0443u044eu0449u0435u0439 zone and u043du0435u043eu043au0438u0441u043bu0438u0442u0435u043bu044cu043du043eu0433u043e catalytic u0434u0435u0433u0438u0434u0440u0438u0440u043eu0432u0430u043du0438u044f n - butane, which are u0433u0430u0437u043eu0432u044b in stream b containing n - butane, 1 - u0431u0443u0442u0435u043d, 2 - u0431u0443u0442u0435u043du044b, butadiene, hydrogenif necessary, water vapor, if necessary, carbon oxide and, if necessary, inert gases; (g) the feed gas flow f, which includes bhutan, u0431u0443u0442u0435u043du044b, boo u0442u0430u0434u0438u0435u043d and received from a gas flow containing oxygen gas b, and at least one second u0434u0435u0433u0438u0434u0440u0438u0440u0443u044eu0449u0435u0439 zone and u043eu043au0438u0441u043bu0438u0442u0435u043bu044cu043du043eu0433u043e u0434u0435u0433u0438u0434u0440u0438u0440u043eu0432u0430u043du0438u044f 1 - and 2 - u0431u0443u0442u0435u043du0430 u0431u0443u0442u0435u043du043eu0432 and receive the gas flow g, containing n - butane.not that u0431u0443u0442u0435u043d (s) 1 and 2 u0431u0443u0442u0435u043du044b, butadiene, water vapor, if necessary, carbon oxides, hydrogen, if necessary and, if necessary, inert gases; and (h) ood u0430u043bu0435u043du0438u0435 residual oxygen contained in a gas stream (g, through the catalytic stage combustionat which oxygen transforms with part or all of the separated hydrogen d2 and / or further by feeding hydrogen to obtain flow u0435u0449u0435u0441u0442u0432 h, depleted of oxygen and the fact that the phase h) are in the presence of a catalyst which comprises a monolith, which shows u043au0430u0442u0430u043bu0438u0442u0438u0447u0435u0441u043a and the inert material of low wet - surface, and a layer of catalystwhich caused the monolith and contains u043eu043au0441u0438u0434u043du044bu0439 material carrier, at least one noble metal selected from the group consisting of noble metals gr u0443u043fu043fu044b viii of periodic system of elements, if necessary, tin
