Gas adsorption analyzer and mercury intrusion meter in the petroleum and chemical industry - Database & Sql Blog Articles

The main difference between gas adsorption analyzers and mercury intrusion meters in the petroleum and chemical industries – gas adsorption analyzers and mercury intrusion meters – is that the specific applications of the two are different in the pore size of the material being studied. That is to say, the nano-scale pore structure is generally analyzed by gas adsorption, and the pore structure of 100 nanometers to micrometers needs to be characterized by mercury intrusion method. Specifically, there are mainly the following aspects: Characterization of the catalyst One of the core technologies of the chemical industry is the synthesis and characterization of the catalyst used. The characterization of the catalyst having a porous structure is mainly achieved by a gas adsorption method, and of course, it is also analyzed by a mercury intrusion method depending on the pore size. Organic materials are used in the development and quality control of adhesives, chromatographic analysis, ion exchange resins and other polymeric materials. The core surface ratio is larger than the surface analysis, and the oil-bearing and gas-structured structure is more. Research and Quality Inspection of Oil-Gas Vapor Conversion Catalyst The catalyst is based on Alfa-Al2O3 and is suitable for the production of ammonia synthesis gas, hydrogen, methanol synthesis gas and other steam conversion processes using gaseous hydrocarbons (such as oil or gas). Study on fly ash ceramsite Sintered fly ash ceramsite is based on fly ash, with a small amount of binder (clay, shale, coal gangue, curing agent, etc.) and solid fuel (such as pulverized coal). An artificial lightweight aggregate obtained by mixing into a ball and baking at a high temperature (1200-1300 ° C). With its high adsorption specific surface characteristics, it only absorbs water and does not absorb oil. It can be used in oil fields to remove water from heavy oil. Development of adsorption gas storage technology The block adsorbent prepared from petroleum coke has a specific surface area of ​​2399 m2/g. At a gas pressure of 4.0 MPa and normal temperature, the weight of methane is 17.5% (weight). The volume ratio (V/V) was 148. Determination of the methane isotherm adsorption line helps to understand the entire adsorption process. In addition to the above specific experimental characterization, gas adsorption and mercury intrusion valves also play an important role in the clastic rock reservoir geological simulation laboratory. At the same time, in the petroleum industry standard (SY/T6154-95) - rock specific surface and pore size distribution determination of static nitrogen adsorption capacity method, the application of gas adsorption method in the industry is more clear.
