Problems solved by technology

At present, most of the analysis of refinery gas samples adopts the RIPP78-90 "four valves and five columns" analysis method in "Petrochemical Analysis Methods". Although the sample analysis is relatively perfect, its disadvantage is that no matter what type of refinery gas sample , the one-way analysis takes nearly 30 minutes, and the separation of the components is not perfect
The key reason for this is the restriction of the support material of the chromatographic column, because the refinery gas sample contains not only light hydrocarbons, but also hydrogen, oxygen, nitrogen, carbon monoxide, carbon dioxide, hydrogen sulfide and other components. tougher
In order to achieve a certain degree of separation, the current method adopted can only be the length of the long chromatographic column (up to 9 meters) and multi-dimensional chromatographic technology to improve the degree of separation, but the problem caused by this is that the analysis time is prolonged. In addition, the investment in experimental equipment has been increased, which has increased the cost of production experiments

Abstract

An aluminium silicide oxide carrier for product analysis is prepared from Al2O3 and Si contained raw material through proportionally mixing at high temp. Its advantages are strong adsorption and desorption power, low cost and high analysis speed.

Description

Technical field [0001] The invention belongs to the technical field of gas sample analysis, and mainly relates to a siliconized alumina carrier. Background technique [0002] The analysis data of the gas refinery is one of the important basis for the smooth operation of the refinery production unit. During the operation of the production unit, the sample analysis is required to be fast and accurate, which can provide the basis for the stable operation of the unit in time. At present, most of the analysis of refinery gas samples adopts the RIPP78-90 "four valves and five columns" analysis method in "Petrochemical Analysis Methods". Although the sample analysis is relatively perfect, its disadvantage is that no matter what type of refinery gas sample , the one-way analysis takes nearly 30 minutes, and the separation of the components is not perfect. The key reason for this is the restriction of the support material of the chromatographic column, because the refinery gas sampl...
