Example Embodiment

[0019] Such as figure 1 with figure 2 As shown, a kind of methyl tertiary butyl ether catalytic distillation tower packing structure is formed by alternately arranging several structured packings 1 and several random catalyst packings 2. The random packing catalyst packing 2 is filled between adjacent structured packings 1. In the gap between the structured packing 1 is an open-cell packing, that is, a certain number of holes are opened in the structured packing to make the random catalyst packing flow between multiple pieces of structured packing, and the random catalyst packing 2 is an open window Diversion packing, thereby increasing the gas-liquid mass transfer area while improving the liquid surface renewal, thereby increasing the catalytic reaction rate and the yield of methyl tert-butyl ether.

[0020] The above method for filling the packing structure of the methyl tert-butyl ether catalytic distillation tower, for the MTBE catalytic distillation tower with an inner diam...

Abstract

The invention relates to a packing structure of a methyl tertiary-butyl ether catalytic distillation tower and a filling method. The packing structure is formed by alternately arranging a plurality ofstructured packing and a plurality of bulk catalyst packing, wherein the bulk catalyst packing fills gaps of the adjacent structured packing. The filling method comprises the following steps: firstlyplacing the structured packing at a certain height in a tower, then filling the bulk catalyst packing in the gaps of the structured packing, after the bulk catalyst packing is filled in the structured packing, placing a structured packing layer, wherein the structured packing layer and the structured packing at the upper layer are placed in a certain angle, then filling the structured packing with the bulk catalyst packing, and repeating the process until reaching the designed packing bed height. The packing structure provided by the invention is simple in structure and convenient to make andmount; dead zones of a catalyst bed and short circuit situations can be effectively reduced, and catalyst efficiency can be improved; porousness of the catalyst bed can be improved, and compaction and crushing situations are avoided; and radial distribution of a fluid in the catalyst bed can be enhanced, and utilization rate of a catalyst is improved.

Description

technical field [0001] The invention relates to the technical field of methyl tert-butyl ether production, in particular to a packing structure and filling method of a methyl tert-butyl ether catalytic distillation tower. Background technique [0002] Methyl tert-butyl ether (MTBE) is an ideal blending component of unleaded high-octane gasoline, and is mostly used as a gasoline additive for vehicles. MTBE is produced by the etherification reaction of isobutene and methanol under the action of a catalyst. The catalytic rectification process is often used in production, and the reaction and separation process are completed simultaneously in the catalytic rectification tower. [0003] Catalytic distillation tower is a new type of chemical separation technology, which was first industrialized in 1981 for the synthesis of methyl tert-butyl ether. Compared with ordinary distillation, catalytic distillation technology has the advantages of high conversion rate, high selectivity, l...
