    摘要： By applying a polymerization catalyst or polymerization initiator directly to a liquid-absorbent or liquid-adsorbent (hereinafter collectively referred to as nullliquid-sorbentnull) substrate, preferably a porous geotextile in sheet material form, to form a polymerization-initiating substrate or sheet material, a slurry of a monomer and a water-absorbent clay that is subsequently embedded in the porous substrate will have its monomer content sufficiently contacted by the polymerization catalyst or polymerization initiator for complete polymerization of the embedded monomer to form embedded polymer solids and clay, without the monomer partially polymerizing before contacting the substrate. It has been found that polymerization of the monomer while in contact with the substrate achieves best results in retention of embedded and interlocked polymer and clay solids. Preferably only the polymerization catalyst or polymerization initiator, and optionally a cross-linker for the monomer, and/or a polymer neutralizing agent, together with any carrier, such as water or an organic solvent, are applied to the liquid-sorbent substrate prior to embedding the monomer into the substrate. In another embodiment, the cross-linker and/or the polymer neutralizing agent are embedded into the substrate together with the polymerization catalyst and/or polymerization initiator.

    摘要： Methods of preparing a mercury sorbent material are provided. The methods comprise making a copper/clay mixture by admixing a dry clay and a dry copper source; making a sulfur/clay mixture by admixing a dry clay and a dry sulfur source; admixing the copper/clay mixture and the sulfur/clay mixture, to form a mercury sorbent premixture; and shearing the mercury sorbent pre-mixture to form the mercury sorbent material. Various substrates may be used with or instead of the clay, and various additives may be added to the copper, sulfur, clay, or mixture thereof.

    摘要： Geocomposite articles that can provide a barrier against high conductivity water e.g., ocean water, are described and their method of manufacture, for waterproofing surfaces that contact high conductivity water. The geocomposite article mat includes a woven or non-woven geotextile sheet or mat containing a powdered or granular partially cross-linked acrylamide/acrylate/acrylic acid copolymer across its entire major surface(s). The powdered or granular copolymer has an unexpectedly high free-swell when hydrated with High Conductivity water, such as ocean water. A liquid-impermeable cover sheet is adhered to the upper major surfaces of the filled copolymer-carrying geotextile to provide a primary high conductivity water barrier layer that, if ruptured, is sealed by the swell of an underlying layer of water-insoluble, partially cross-linked acrylamide/acrylic acid copolymer.

    摘要： Described herein, in the preferred embodiment, is a leonardite-based polyurethane resin binder that may be used, among other applications, as a binder in combination with foundry aggregate, e.g., sand, for molding or casting metal parts. The binders described herein comprise a humic substance, preferably leonardite, combined with a polymerizable polyol, an isocyanate, and a polymerization catalyst to make a polyurethane resin binder in situ in a foundry aggregate, such as sand. The lignite is mixed with the polymerizable polyol and dispersing agents as additives to improve the suspension quality and binder performance of the lignite-containing part of the binder components.

    摘要： Apparatus in fluid communication with a water leg portion of a hydrocarbon-contaminated water, e.g., a water leg portion of an offshore drilling or production platform sump tank for conveying water, separated from oil, into contact with organophilic media canisters such that the hydrocarbons and other organic materials commingled with the sump tank water will be adsorbed onto the organophilic media and detected by the embedded probe in selected canisters. The canisters are provided in a plurality of stacks and are in fluid communication with a header disposed at the bottom of the vessel housing the various stacks of canisters. Solids that do not pass through the canisters are accumulated at the bottom of the vessel and easily drained through a drain port. The water will pass through the media and will be conveyed back to the ocean water without contamination. At some point in time, the organophilic media will become nullspentnull and at a certain nullspent levelnull, the saturated condition of the organomedia will be electronically detected by the embedded probe and alarm/control panel. The alarm indicates that the nullspentnull organophilic media should be replaced with fresh media or the spent media regenerated.
