  • Patent number: 11866652
    Abstract: This disclosure relates to a procedure, which through the application of a catalyst in homogeneous phase, allows the transformation of heavy hydrocarbons (vacuum residue, atmospheric residue, heavy and extra-heavy crudes) into hydrocarbons of lower molecular weight, characterized because after its application, the hydrocarbons obtain greater API gravity, lower kinematic viscosity and different composition by hydrocarbon families (SARA) that increases the proportion of saturated and aromatic resins and asphalts. The sulphur and nitrogen content is also reduced, resulting in higher yields to high commercial value distillates and a lighter product as compared to the original crude.

  • Publication number: 20230064148
    Abstract: In this invention is described: a) the preparation of a new heterogeneous catalyst based on mesoporous silica with variable geometry of pore arrangement, covalently functionalized by an ionic liquid and as a counterion a tungsten polyoxometalate (Keggin acid); b) the application of this catalyst with dual action: Bronsted-Lowry acid and oxidizing agent; and c) its application in chemical reactions is described as: condensation, oxidation, polymerization, and esterification. This type of catalyst offers the following advantages in the chemical industry 1) reusable; 2) promotes different transformations in a single stage, attributed to their acidic and oxidizing characteristics (dual action); and 3) efficiency in the chemical transformations described, which allow to obtain precursors of homogeneous hydroprocessing catalysts, of interest for some projects of transformation of heavy crude oils in situ.

  • Patent number: 10551335
    Abstract: The object of the present invention relates to a system for measuring the salinity of hydrocarbons at the bottom of an oil well, using the technique of time domain reflectometry (TDR). The system comprises an electromagnetic pulse generator, an oscilloscope for displaying and measuring the frequency, amplitude and wavelength of the signal, a signal amplifier, a computer for processing and storing the information, and a metal wire that functions as a waveguide To transmit the signal from the signal generator to the hydrocarbon to which its salinity is to be determined at the bottom of the well. The signal returns from the bottom of the well to the oscilloscope where the difference between the sent signal and the return signal is measured. This difference allows us to infer the salinity of the hydrocarbon.

  • Publication number: 20190233738
    Abstract: A process is disclosed for removing fluoridated compounds from any organic medium, for example from alkylation (“alkylated”) gasoline, which can be applied at the exit of the alkylation process or inside the distillation column of the alkylation process. The process uses extractant chemical agents based on ionic liquids, of general formula C+A?, where C+ represents an organic or inorganic cation, specifically imidazolium, pyridinium, or ammonium salts, while the anion A? represents the halide-type derivatives, iron (III) salts, aluminum (III) salts, acetate, benzoate-acetates, benzoates, hexafluorophosphate, tetra-chloroborate, triflates, bis-triflates and trifluoroacetates. These ionic liquids act as extractant agents to remove fluoridated compounds from the hydrocarbon streams that are produced in the process of alkylation of isubutane with butenes, through a liquid-liquid extraction process, with a reduction of more than 80% in the content of contaminants like organofluoridated hydrocarbons.

  • Publication number: 20190017359
    Abstract: The invention relates to systems, apparatus and methods for integrated recovery and in-situ (in reservoir) upgrading of heavy oil and oil sand bitumens. The systems, apparatus and methods enable enhanced recovery of heavy oil in a production well by introducing a hot hydrocarbon fluid from a mobile reservoir into the production well under conditions to promote hydrocarbon upgrading. The methods may further include introducing hydrogen and a catalyst together with the injection of the hot fluid into the production well to further promote hydrocarbon upgrading reactions. In addition, the invention relates to enhanced oil production methodologies within conventional oil reservoirs.

  • Patent number: 10000457
    Abstract: The present invention relates to a process of synthesis of certain ionic liquids di-polymerized based Radziszewsky type reaction, whereby primary amines containing at least one terminal functional group, for example —OH, aldehydes and a mineral or organic acid, react exothermically in a single step, thus resulting in an ionic liquid by condensation, then oxirane derivative molar quantities are added, by controlling the temperature and pressure a di-polymerized ionic liquid is obtained. The process of the present invention is advantageous because it provides a synthesis scheme for di-polymerized ionic liquids, primarily using short reaction times and high performance; this process can be further scaled for industrial production and it can accept alternative chemical precursors of lower cost.

  • Patent number: 9790446
    Abstract: The present invention relates to the use of a chemical composition to modify the physical properties (viscosity and interfacial tension) of heavy and extra-heavy crude oils, to increase their mobility. The chemical composition comprises or consists of a combination of systems based on ionic and non-ionic liquids, which may be pure or modified, mixed in an aqueous or organic medium as a dispersing agent, depending on the nature of the crude to be treated, together with a surfactant. The composition is mixed with the crude oil at a temperature between 5 and 100° C., at pressures from 1 atm (14.7 psi) up to about 680.2 atm (10,000 psi). The composition can be mixed with heavy crude oils, at the point of extraction from the well in the field, during the transport of crude oil in pipelines, or in the well discharge pipelines.
