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

Example Embodiment

[0010] This invention is made by Al 2 O 3 The raw material reacts with the silicon-containing raw material for several hours (2-10 hours) at high temperature to generate silicified alumina. Examples of its application to refinery gas samples are as follows:

[0011] Refinery gas type

[0012] It can be seen from the composition of various samples in the table that the main sample components to be measured are: hydrogen, carbon dioxide, oxygen, nitrogen, carbon monoxide, hydrogen sulfide, sulfur dioxide, carbonyl sulfide, methane, ethane, ethylene, propane, propylene, Isobutane, n-butane, 1-butene, isobutene, butene, butene, 1,3-butadiene, isopentane, n-pentane, other small amounts of carbon five to carbon six and other components.

[0013] Principle of experimental method:

[0014] This experimental method is based on the different composition of refinery gas samples, using the "three-valve, four-column and double thermal conductivity" analysis method to separate two dif...

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...
