  • Publication number: 20220225609
    Abstract: A multiple-loaded non-ceramic dry carrier product and method for the loading of reagent liquids, solids dissolved in liquids as solutions, suspensions, and solids heated to reduce viscosity, onto perlite, pumice, scoria, or exfoliated vermiculite or activated charcoal particles, which are used as carriers, and then dried in multiple iterations to achieve a powdered, free-flowing material for use in hydraulic fracturing processes and other uses such as environmental remediation and animal control, providing improvements in cost, carrier stability, and chemical retention properties.

  • Publication number: 20180229191
    Abstract: Process for internally loading liquids onto carriers and achieving time-release dry liquid concentrate. The resulting time-release dry liquid concentrates having a variety of applications, including animal attractants and repellants, down hole chemicals, flavors and fragrances of food and beverages, treatment of contaminants, fertilizers, vitamins.

  • Publication number: 20180230361
    Abstract: Fracturing-fluid products and a method of making up an expanded list of viable chemical carriers that improve the economic considerations and competition in the industry, improve carrier stability and chemical retention duration, and provide the most effective and safest fracturing fluid for each of the many varied conditions and varied processes which use some form of hydraulic fracturing, by loading liquids, solutions of solids dissolved in liquids, suspensions, or solids heated to reduce viscosity onto scoria, perlite, pumice, aerogels, activated alumina, fullerenes, graphite, molybdenum, magnetite, vermiculite, and activated charcoal to achieve a dry liquid concentrate (“DLC”) or slurry, for use in processes where a substance or substrate is to be expanded by a pressurized propellant and held in an expanded state by a proppant of granular solid material, including, without limitation, hydraulic fracturing for hydrocarbons, manufacturing, oil well treatment and production chemicals, biological treatment an
