摘要： The invention relates to a method for producing isobutene by cracking MTBE, wherein the following steps are carried out: a) MTBE synthesis; reacting isobutene-containing hydrocarbon mixtures (II) with methanol (III), contained in one or more methanol-containing streams (VIII, IX), on acidic ion exchangers obtaining a stream (IV) containing MTBE and TBA, b) MTBE separation; separating a stream (V) containing MTBE and TBA from stream (IV) by means of distillation, c) MTBE cracking; cracking the stream (V) on a heterogenic catalyst in the gas phase, thus obtaining a stream (VI) which contains at least isobutene, methanol, MTBE, water, and optionally TBA, d) isobutene separation; separating the stream (VI) by means of distillation, thus obtaining a stream (VII) containing more than 50 mass % of the amounts of methanol, TBA, and water contained in stream (VI), and a stream (XVII) containing isobutene, e) water separation; separating, water from the stream (VII) to below 1 mass % by means of distillation, thus obtaining a stream (VIII), f) recirculating; complete or partial recirculation of the methanol-containing stream (VIII) into the MTBE synthesis. The invention further relates to a tube bundle device comprising the following elements: i) tube bundle, ii) tube bottom, iii) deflection plates, iv) inner shell, iv) pressure bearing outer shell, comprising at least one inlet and outlet, vi) shell chamber, comprising a fluid releasing or absorbing heat, characterized in that the inner shell is connected to the deflection plates attached over the length of the tube bundle without a gap, or with a small gap, and is connected to the tube bottom, wherein the fluid present in the shell chamber encloses the inner shell on both sides.

摘要： The invention relates to a method for the efficient purification of MTBE-containing mixtures and for producing isobutene by cleavage of MTBE-containing mixtures. Technical MTBE is separated by distillation into a C4- and C5-hydrocarbon-containing top product, an acetone, methanol and MTBE-containing side cut, and an MTBE-containing bottom product.

摘要： Disclosed is a method for telomerizing non-cyclic olefins comprising at least two conjugated double bonds with at least one electron donor by using a catalyst that contains a metal from group 8, 9, or 10 of the periodic table. The inventive method is characterized in that hydrogen is fed to the process via a hydrogen source in at least one step of the entire telomerization process.

摘要： The invention relates to a process for production of isobutene from MTBE-containing mixtures which comprises the following steps a) cracking, in a reactor R, a mixture obtained from an MTBE-containing feedstock (1a) and/or an MTBE-containing stream (13, 5), delivering a stream (6) of reaction products consisting of isobutene, methanol, MTBE and also by‑products, wherein these consist of a1) high boilers having a boiling range above 55°C at a pressure of 0.1 MPa; a2) medium boilers having a boiling range from 12 to 55°C at a pressure of 0.1 MPa; and a3) low boilers having a boiling range below 12°C at a pressure of 0.1 MPa; b) separation of stream (6) by distillation into a stream (7) which contains the product isobutene and low boilers and a stream (8) which contains MTBE, methanol, medium boilers and high boilers; c) separating the stream (8) by distillation obtaining an MTBE-containing stream (10, 12) and a methanol-containing high-boiler stream (9, 11); d) recirculating an MTBE-containing stream (10, 12, 13) to step a) of the process, wherein the medium-boilers are completely or partially separated off from the medium-boiler-rich streams (10, 12) upstream of step d).
