A method for preparing hydrocarbons is proposed, which comprises, in a catalysis unit (1) using one or more catalysis feed streams (a) containing oxygenates and/or olefins, producing a catalysis product stream (b) containing n-butane, isobutane, 1-butene, 2-butene, isobutene and hydrocarbons with more than four and/or less than four carbon atoms, and which further comprises producing a steam cracking product stream (s) in a steam cracking unit (2) using one or more steam cracking feed streams (g, n, l, r). It is provided that at least the great majority of the hydrocarbons with more than four and/or less than four carbon atoms and the isobutene is eliminated from the catalysis product stream (b) or a part thereof, whereby a stream (g, n) containing at least 5 percent by mole 1-butene and/or 2-butene is formed, and in that this stream (g, n) containing at least 5 percent by mole 1-butene and/or 2-butene or one or more streams (l, r) derived therefrom is or are used as the steam cracking feed stream or streams (g, n, l, r). The invention also relates to a corresponding apparatus (100, 200, 300).
Method for preparing hydrocarbons, which comprises, in a catalysis unit (1) using one or more catalysis feed streams (a) containing oxygenates and/or olefins, producing a catalysis product stream (b) containing n-butane, isobutane, 1-butene, 2-butene, isobutene and hydrocarbons with more than four and/or less than four carbon atoms, and which further comprises producing a steam cracking product stream (s) in a steam cracking unit (2) using one or more steam cracking feed streams (g, n, l, r), characterised in that at least the great majority of the hydrocarbons with more than four and/or less than four carbon atoms and the isobutene is eliminated from the catalysis product stream (b) or a part thereof, whereby a stream (g, n) containing at least 5 percent by mole 1-butene and/or 2-butene is formed, and in that this stream (g, n) containing at least 5 percent by mole 1-butene and/or 2-butene, or one or more streams (l, r) derived therefrom, is or are used as the steam cracking feed stream or streams (g, n, l, r).
Apparatus (100, 200, 300) for the production of hydrocarbons, having a catalysis unit (1) which is set up so as to produce, using one or more catalysis feed streams (a) containing oxygenates and/or olefins, a catalysis product stream (b) containing n-butane, isobutane, 1-butene, 2-butene, isobutene and hydrocarbons with more than four and/or less than four carbon atoms, and having a steam cracking unit (2) which is set up to produce a steam cracking product stream (s), using one or more steam cracking feed streams (g, n, l, r), characterised in that means are provided which are set up to eliminate, from the catalysis product stream (b) or a part thereof, at least the great majority of the hydrocarbons with more than four and/or less than four carbon atoms and the isobutene, whereby a stream (g, n) containing at least 5 percent by mole 1-butene and/or 2-butene is formed, and in that means are provided which are set up to use this stream (g, n) containing at least 5 percent by mole 1-butene and/or 2-butene, or one or more streams (l, r) derived therefrom, as the steam cracking feed stream or streams (g, n, l, r).
