用于制备烃类的方法和设备
摘要：
本发明涉及用于制备烃类的方法，其中在催化单元(1)中并且采用一种或多种含有含氧化合物类和/或烯烃类的催化进料流(a)制备富含正丁烷、异丁烷、1‑丁烯、2‑丁烯、异丁烯和具有多于四个碳原子和/或少于四个碳原子的烃类的催化产物流(b)，和其中还在蒸汽裂化单元(2)中并且采用一种或多种蒸汽裂化进料流(g、r、s)制备蒸汽裂化产物流(h)。根据本发明，采用催化产物流(b)制备贫含1‑丁烯、2‑丁烯和异丁烯和至少含有异丁烷的骨架异构化进料流(f、q)，至少大部分的异丁烷在所述骨架异构化进料流中通过骨架异构化进行反应，以获得正丁烷，这一骨架异构化进料流随后至少部分地被用作蒸汽裂化进料流(g、r)或蒸汽裂化进料流(g、r)中的一种。本发明还涉及设备(100、200)。
摘要（英）：

The invention relates to a method for producing hydrocarbons in which, in a catalysis unit (1) and using one or more catalysis input streams (a) containing oxygenates and/or olefins, a catalysis product stream (b) is produced that is rich in n-butane, isobutane, 1-butene, 2-butene, isobutene and hydrocarbons having more than four and/or less than four carbon atoms, and in which, in a steam cracking unit (2) and using one or more steam cracking input streams (g, r, s), a steam cracking product stream (h) is also produced. According to the invention, a skeletal isomerisation input stream (f, q) which is low in 1-butene, 2-butene and isobutene but contains at least isobutane is produced using said catalysis product stream (b), at least the majority of the isobutane being reacted by means of skeletal isomerisation in said skeletal isomerisation input stream so as to obtain n-butane, and this skeletal isomerisation input stream subsequently being used, at least in part, as the or one of the steam cracking input streams (g, r). The invention also relates to an installation (100, 200).
