A product, a method of producing and a method of using are disclosed. The product comprises attapulgite that has been thermally activated. The product may have a permeability in oil in the range of 0.04-3 darcy and may have a surface area of 45-140 m.sup.2/g. The method of producing may comprise thermally activating a material that includes attapulgite by heating the material at a temperature in the range of 300 to 900° C. The method of decolorizing may include contacting for a contact time an oil with the bleaching clay product that comprises attapulgite that has been thermally activated, and separating the bleaching clay product from the oil to recover a decolorized oil that has a lower red color than the oil had prior to the contacting, and removing phosphorus and metals for hydrotreated vegetable oil (HVO)/renewable diesel feedstock pretreatment.

A composition and method for sorbing a mobilized metal which can optionally include uranium, and which can optionally be used for capping uranium-containing mining tailings. The method can include forming a layered structure atop the metal-containing mining tailings which sorbs the metal and prevents it from being discharged as surface water runoff and which prevents it from being released into groundwater.

The present invention relates to a neutralizing absorbent for decontaminating a leaked chemical substance, a method of preparing the same, and a neutralizer filled with the same. The neutralizing absorbent for decontaminating a leaked chemical substance according to the present invention includes an inorganic adsorbent, which is commonly usable in neutralizing absorption of acidic, basic, and/or organic chemical substances, at 40 to 60 wt %, a thickener at 20 to 30 wt %, a surfactant at 20 to 30 wt %, and a color change indicator, and is formulated in a solid state. The neutralizing absorbent is effective in promptly and safely taking an initial action regardless of the type, nature, and characteristics of acidic, basic, and/or organic chemical substances leaked in the leakage accident of the chemical substance, and accordingly, is useful in preventing secondary accidents. Also, when the neutralizing absorbent is used, there are no concerns about the spread of contamination due to water generated by an acid-base reaction, concerns about the additional occurrence of secondary contamination due to a decontaminating agent can be minimized by using a non-toxic chemical absorbent, and a decontamination process can be visually checked in real time regardless of the type, nature, and characteristics of the leaked chemical substance. Furthermore, when a neutralizer filled with the neutralizing absorbent for decontaminating a leaked chemical substance according to the present invention is used, the leaked chemical substance can be more safely and effectively decontaminated during an initial action.
