    摘要： The invention relates to a method for the production of 1,2-dichloroethane, comprising the following steps: (A) feeding a feed gas flow containing an ethane into a dehydrogenation zone; dehydrogenating the ethane into ethene while obtaining a product gas flow containing ethane, ethene and minor constituents; (B) feeding the dehydrogenated product gas flow containing the ethane and ethene into a flow or several partial flows, optionally after separating the minor constituents, in one or more chlorination zones; chlorinating ethene into 1,2-dichloroethane while obtaining one or more product gas flows containing 1,2-dichloroethane, ethane and optionally other minor; obtaining 1,2-dichloroethane and one or more circuit gas flows containing ethane and recirculating the circuit gas flow(s) containing ethane to the ethane dehydrogenation.

    摘要： The invention relates to a method for producing butadiene from n-butane comprising the following steps: A) provision of a feed gas stream (a) containing n-butane; B) introduction of the feed gas stream (a) containing n-butane into at least one first dehydrogenation zone and the non-oxidative catalytic dehydrogenation of n-butane to obtain a product gas stream (b) containing n-butane, 1-butene, 2-butene, butadiene, hydrogen, low-boiling minor constituents, optionally carbon oxides and optionally water vapour; C) introduction of the product gas stream (b) of the non-oxidative catalytic dehydrogenation and a gas containing oxygen into at least a second dehydrogenation zone and the oxidative dehydrogenation of n-butane, 1-butene and 2-butene to obtain a product gas stream (c) containing n-butane, 2-butene, butadiene, low-boiling minor constituents, carbon oxides and water vapour, said stream having a higher butadiene content than the product gas (b); D) isolation of the low-boiling minor constituents and the water vapour to obtain a C4 product gas stream (d), which essentially consists of n-butane, 2-butene and butadiene; E) separation of the C4 product gas stream (d) into a stream (e1), which essentially consists of n-butane and 2-butene and a useful product stream (e2), which essentially consists of butadiene, by extractive distillation; F) return of the stream (e1) to the first dehydrogenation zone.
