    摘要: The instant invention is directed to a process for making a non-woven, wet-laid, superabsorbent polymer-impregnated structure. The process generally comprises the steps of: mixing; deliquifying; and drying. Specifically, fibers, superabsorbent polymers, and a liquid are mixed to form a furnish. The liquid is treated with a means for inhibiting the swelling of the superabsorbent polymer. Then, the furnish is deliquified to form a preformed structure. The preformed structure is dried to form the non-woven, wet-laid, superabsorbent polymer-impregnated structure.

    摘要: The present invention relates to a method for removing oil from water or a solid surface. This involves contacting the water or the solid surface with a substance in the form of a sheet and having a high humate level under conditions effective for the substance to absorb oil from the water or the solid surface. The substance, having absorbed oil, is then recovered from the water or solid surface. In an alternative embodiment this method can be carried out where the substance is manure which may or may not be in the form of a sheet.
