METHOD FOR ESTIMATING DYNAMIC ADSORPTION OF CATALYTIC ELEMENTS FROM COMPOSITIONS ON RESERVOIR ROCKS Russian patent published in 2025 - IPC G01N11/00 

FIELD: chemistry.

SUBSTANCE: invention relates to chemical, petrochemical and oil industry. Disclosed is a method for estimating the dynamic adsorption of catalytic elements from compositions on reservoir rocks, consisting in the fact that a catalyst solution is prepared, a standard sample is prepared, hydrocarbon extraction of the sample is performed, then determining its effective porosity volume and measuring the standard sample weight, then saturating the core sample with water or oil with residual water, installing the core sample in the filtration unit, wherein the apparatus is equipped with a sample collector for successively collecting output fractions of the filtered liquid with volume of 1 ml, then setting the formation or model values of the crimping pressure, temperature and filtration linear velocity, filtering the catalyst solution through the core with sampling of each 1 ml of the outgoing liquid, measuring concentration of catalyst in initial solution and in selected samples using ICP-MS method, calculating adsorption value in each sample, wherein dynamic adsorption is determined based on additive adsorption value.

EFFECT: invention enables to determine the value of dynamic adsorption of catalytic elements.
