Abstract

The invention provides an isomerization reactor component made from sealing fabric. The isomerization reactor component is of a multilayer fabric sewn structure and comprises an upper laying layer, a middle layer and a lower laying layer. The upper laying layer and the lower laying layer are each of a ceramic fiber fabric structure. Each fabric structure is formed by stacking and laying a single layer or multiple layers of ceramic fiber cloth. The middle layer is made of stainless steel metal foil. The reactor component can be formed by combining and splicing multiple fabric units. Fabric unit blocks are each of a multilayer fabric sewn structure, and the fabric unit blocks are combined and spliced through connecting pieces. A preparation method of the reactor component includes the steps that the sizes of the fabric unit blocks are designed firstly, and the upper laying layer, the middle layer and the lower laying layer are cut; then laying is conducted layer by layer according to the scheme; stacked sewing is conducted, and the fabric unit blocks are obtained; finally, the fabric unit blocks are combined and spliced into a whole through the connecting pieces. The product is good in high temperature resistance, low in cost and convenient to manufacture, and the use effect of an isomerization reactor catalyst can be remarkably improved.

Description

technical field [0001] The invention relates to a reactor internal component and a preparation method thereof, in particular to an isomerization reactor component for preparing xylene and a preparation method thereof. Background technique [0002] Xylene is widely used as a solvent in coatings, resins, dyes, inks and other industries, as a synthetic monomer or solvent in medicine, explosives, pesticides and other industries, and as a component of high-octane gasoline. important raw material. The disproportionation method is an important method for producing xylene, and the isomerization reactor is its core device. [0003] The existing foreign-designed isomerization reactor is a radial fixed bed, and the seal on the upper part of the catalyst in the device is in the form of a bell jar made of stainless steel plate, which is suspended on the top head of the reactor. The role of the bell jar is to guide the oil and gas entering the reactor into the fan-shaped tube on the wal...
