    摘要: A method of purifying a rendered fat by contacting the rendered fat with at least one adsorbent material, such as magnesium silicate. The at least one adsorbent material may be used alone or in combination with other purifying materials, such as an acid. Such method provides for improved removal of impurities, such as polyethylene, phosphorus-containing compounds, chlorophyll, metals, soap, and sterol glucosides from the rendered fat.

    摘要: A method of treating a fruit-based or vegetable-based beverage to remove chill haze components therefrom which comprises contacting the beverage with an effective amount of an amorphous hydrous precipitated synthetic magnesium silicate which has been treated to reduce the pH thereof to less than about 9.0. Such a method is particularly applicable to the treatment of beer and related beverages and provides for improved removal of chill haze components from such beverages.

    摘要: A filter for removing undesired materials from a fluid, such as used cooking oil, for example, includes a filter envelope including first and second panels. The first panel has a permeability which is greater than that of the second panel. The first panel of the filter envelope may be formed from a filter pad and the second panel from a filter paper, and may enclose a metal spacer grid. When the filter is connected to a pump for drawing the oil through the filter, the flow of the oil is directed selectively through the filter pad, whereby undesired materials are removed from the oil. The filter provides for efficient flow of the oil to be filtered while removing undesired materials therefrom.

    摘要: A process for treating cooking oil or fat which comprises contacting cooking oil or fat with magnesium silicate and at least one alkali material, such as, for example, calcium hydroxide. The magnesium silicate and at least one alkali material are present in amounts effective to reduce the content of free fatty acids in the oil or fat and permit reuse of the oil or fat for cooking. Such method provides for improved extension of the life of the cooking oil employed in restaurant-type and industrial frying operations.

    摘要: A quick, economical and environmentally friendly, “green”, process for the continuous purification of biodiesel (fatty acid alkyl esters (FAAE)) is described using a powdered, granulated or extruded adsorbent. The adsorbent is contained in a column system and is regenerated for reuse multiple times. The process employs an adsorbent such as, but not limited to, carbon, silica, clay, zeolite or a metal silicate contained in a column to remove the impurities from fatty acid alkyl esters (FAAE) or crude biodiesel in a continuous process. The process utilizes the adsorbent column system for the purification of biodiesel, rather than water or filtration, to remove soaps and other impurities entrained in a crude biodiesel. The crude biodiesel is contacted with an adsorbent packed into a column, or multiple columns in series, for a sufficient amount of time to remove impurities such as, but not limited to, soaps, metals, free glycerin, sterol glucosides and many of the other impurities that reduce the stability of biodiesel. The resulting finished biodiesel exiting the column(s) is ready for the methanol recovery process. Once the adsorbent no longer removes the desired amount of impurities, it is regenerated for reuse. The solvent used for the regeneration process is reclaimed and reused by recycling it back to the transesterification reaction.
