摘要： The invention relates to a process for obtaining isobutene from an isobutene containing C4-hydrocarbon mixture (1) in a plant comprising an etherification unit (3), a first distillation unit (5), an ether cleavage unit (8) and a second distillation unit (10), the process comprising:
(a) contacting the C4-hydrocarbon mixture (1) with a primary alcohol (2) and reacting the mixture with the primary alcohol in the presence of an acidic catalyst to form the corresponding alkyl tert-butyl ether as an intermediate product and diisobutene as a byproduct in the etherification unit (3);
(b) distilling the reaction mixture (4) from the etherification unit (3) in the first distillation unit (5), a C4-hydrocarbon raffinate being withdrawn as the overhead product (6), the alkyl tert-butyl ether and diisobutene being withdrawn as the liquid or vaporous bottom product (7), and vaporizing the bottom product (7) if it is withdrawn as a liquid;
(c) reacting the vaporous bottom product (7) in the presence of an acidic catalyst obtaining isobutene and the primary alcohol as reaction products in the ether cleavage unit (8);
(d) distilling the reaction mixture (9) from the ether cleavage unit (8) in the second distillation unit (10), isobutene being withdrawn as the overhead product (11), the primary alcohol and diisobutene being withdrawn as the bottom product (12) and being recycled to the etherification unit (3);
the plant further comprising a byproduct separation unit (15) being fed by a bottom purge stream (13) of the first distillation unit (5) and/or by a part of the bottom product of the second distillation unit (10), wherein a diisobutene product stream rich in diisobutene is separated from this feed stream (13, 14).

摘要： The invention relates to a process, unit and reaction system of low-carbon alkane dehydrogenation, which comprises the following steps: C3-C5 low-carbon alkane feed gas, together with CO and/or CO 2 process gas, get into reactor after being preheated to 200-500°C, contact with a Cr-Ce-Cl/ Al 2 O 3 dehydrogenation catalyst, a Cu-Ce-Ca-Cl/Al 2 O 3 thermal generating agent and thermal storage/support inert alumina balls, and convert to dehydrogenation products for 5-30 minutes under the conditions: temperature, 500-700°C, pressure, 10-100 kPa and weight hourly space velocity (WHSV), 0.1-5 hours -1 . The products formed enter the downstream separation unit for separating out the low-carbon alkenes. The periodic regeneration process of the catalyst bed includes steam purging, hot air regenerating, bed heating, evacuating and reducing at 560 to 730°C and 0.01 to 1 MPa. Each cycle needs about 10-70 minutes. With such dehydrogenation process, the reaction heat balance is moderated, and temperature gradient and reaction severity in the catalyst bed are reduced. As a consequence, the catalytic conversion, product selectivity, operation cycle and service life are improved. The system energy consumption is reduced.

摘要： The present invention discloses an integrated process and an apparatus for production of various alcohols and Oligomerization of Olefinic feed stocks comprising butylenes and mixture thereof. In this process the combined light olefinic hydrocarbon feedstock is divided into two streams and contacted in two different reaction zones, viz. hydration and oligomerization. The mixture of alcohols and oligomer product from hydration reaction is separated and the bottom stream from separator is routed to oligomerization reaction zone in a controlled quantity as selectivity enhancer. Both the reaction zones are operated at different conditions. The product from oligomerization zone is further separated in to lighter and heavier components. Each reaction zone may comprise series of reactors filled with acidic catalysts comprising ion exchange resins.
