Abstract

The utility model discloses an activator carrier with holes on the side and comprises axial central air flow through holes, as well as axial air flow through holes and sideward air flow through holes evenly arranged around the axial central air flow through holes; upper and lower end faces and side faces are connected with each other through arc faces; wherein, the axial air flow through holes and sideward air flow through holes are arranged with spaces between each other; an axial air flow through hole is communicated with the two adjoined sideward air flow through holes; while an sideward air flow through holes is communicated with the two adjoined axial air flow through holes; and all sideward air flow through holes are separated from the axial central air flow through holes. The utility model communicates fully the axial air flow through holes with the sideward air flow through holes to form an axial and sideward beehive structure, thus the contacting time of the air and the activator is prolonged with the staying time prolonged, which makes the catalyzing better and the strength of the catalyzing grains higher.

Description

The curved-surface structure catalyst carrier

Technical field

The utility model relates to a kind of catalyst carrier, particularly relates to the catalyst carrier of a kind of side perforate.

Background technology

The curved-surface structure catalyst is powdery non-activity oxide, amphoteric oxide, basic anhydride and nonmetal oxide thereof to be prepared into meet conversion, cracking, the synthetic curved-surface structure catalyst carrier that requires, it is the catalyst that uses in the typical gas one solid catalysis reaction, such as, the catalyst in conversion of natural gas catalyst, transformation catalyst, desulphurization catalyst, organic chemical industry field or the like.

The carrier format of the catalyst of present domestic use mostly is annular, wheel shape, porous card shape, porous spherical, groove shape etc.Generally speaking, generally be following three aspects to the requirement of catalyst: the first, the geometric outer surface that increases catalyst to greatest extent is long-pending; The second, increase conversion, cracking or synthesis rate in the catalyst unit interval, promptly improve catalytic efficiency; The 3rd, the bridge formation factor that produces when eliminating catalyst filling to greatest extent.

In order to achieve the above object, Chinese patent ZL95241741.3 discloses the catalyst of a kind of side perforate, it is on the catalyst carrier that axially has through hole, be provided with the sidewise hole that is communicated with central through hole in the side, and the junction of side and end face is designed to the circular arc joint face, increase the external surface area of catalyst preferably, improved catalytic efficiency effectively, reduced the influence of the resistance that produces when catalyst breaks.But the inreal catalyst splintering problem in use that solves of this technical scheme its essence is because the hole that open its side is darker, and the ability of catalyst granules being born the pressure of gas and impact is desirable not enough.

The utility model content

The purpose of this utility model is to be to overcome the shortcoming of above-mentioned prior art and to provide a kind of catalyst granules intensity high catalyst carrier.

The object of the present invention is achieved like this:

A kind of curved-surface structure catalyst carrier, contain axial centre air-flow clear opening, equally distributed axial flow clear opening of central gas stream clear opening circumference and lateral airflow through hole vertically, and the upper and lower end face is connected by arc surface with the side, wherein axial flow clear opening and lateral airflow through hole are set in distance, one axial flow clear opening all is communicated with adjacent two side direction air communication holes, and a lateral airflow through hole all also is communicated with adjacent two axial air-flow clear openings, and all lateral airflow through holes and axial centre air-flow clear opening are isolated.

The utility model is communicated with axial flow clear opening and lateral airflow through hole fully, formed a kind of axially, side direction all is cellular structures, like this, gas and catalyst are more time of contact, the time of staying is longer, catalysis gets more abundant.Adopt catalyst granules intensity of the present utility model and catalytic efficiency in order to prove, in the production process of the conversion of reality and cracking stock gas, carried out using experiment, temperature, pressure are adjusted to the parameter that normal process requires, use the utility model after 120 hours continuously, the breakdown rate of this catalyst carrier is 0%, at all without any damaged and fracture, and adopt patent scheme in the background technology, the breakdown rate of its catalyst carrier is 1.2%; Simultaneously, under same experiment condition, catalytic reaction efficient of the present utility model has improved 0.03 percentage point than the patent scheme in the background technology.
