Autoclave Research of Catalytic Conversion of Hydrocarbon Raw Materials

Currently, processes such as cracking, reforming, hydrotreating, isomerization, and acetylation of hydrocarbons are well-known and widely used in the industrial processing of hydrocarbon feedstock. However, their application under reservoir conditions in oil and gas condensate fields for the purpose of intensifying hydrocarbon inflow remains insufficiently studied and requires a comprehensive range of research.The studies are conducted using an experimental setup consisting of two thick-walled cylindrical working chambers. The design of these cylinders is intended for catalytic process research under conditions close to those found in reservoirs, with the ability to accommodate rock samples.During the experiment, a catalytically active mixture is added to a measured volume of crude oil or gas condensate and loaded into the buffer chamber of the setup. The working flu-id is then injected under pressure into the reactor, where it is heated to the required reaction temperature.In the course of the study, a formulation for a catalytically active mixture was developed. The influence of the composition and mass ratios of the catalyst's active components on the fractional composition and physicochemical properties of crude oil and gas condensate samples was investigated. Based on the obtained results, it can be concluded that the proposed method for enhancing the recovery of hard-to-extract hydrocarbons via catalytic transformations is effective.Unlike conventional hydrocracking processes, this technology involves conducting catalytic transformations under in-situ reservoir conditions directly within the productive formation. The proposed catalytic mixture demonstrates significant catalytic activity at relatively low reaction temperatures ranging from 80 to 140 °C. Moreover, the treatment process of the reservoir rock with the catalyst is similar to typical treatments using surfactants. As a result, this approach can increase oil recovery, enable the development of hard-to-recover reserves, and significantly improve hydrocarbon displacement and flow to the surface.
