    摘要： The present invention relates to a biological process for regenerating metal-containing sulfide mitigation catalysts that are commonly known in the natural gas processing industry as liquid redox catalysts. The invention further relates to a sulfide mitigation process wherein mitigation and regeneration are performed in a single reactor under substantially anaerobic conditions. The present invention also relates to a self regenerating catalyst composition for the mitigation of sulfides.

    摘要： An adsorbent that can be used to remove environmental contaminants such as organics, cations and anions in a single process step is prepared from humic acid. The adsorbent can be a soluble humic acid in liquid form (e.g., in aqueous solution) or the humic acid can be insolubilized and/or immobilized on a solid support. The adsorbent can also be used to recover agriculturally desirable metals in chelated form from contaminated water. The liquid form of the adsorbent can be used to wash solids to remove contaminants.

    摘要： An anaerobic process of desulfurizing a sour natural gas stream wherein a selected consortium of chemoautotrophic bacteria converts H.sub.2 S and other sulfur species into elemental sulfur, which is recovered as a product. The process is conducted at pressures of up to 1000 psi and temperatures up to 140.degree. F. (10.degree. C. to 60.degree. C.), and mitigates up to 10,000 ppm H.sub.2 S to pipeline standards of .ltoreq.4 ppm and up to 10% CO.sub.2 to .ltoreq.2% CO.sub.2.

    摘要： A one step process is provided which denitrifies explosives and propellants and reclaims the evolved nitrogen therefrom while concurrently modifying the remaining carbonaceous materials into humic acid suitable for plant fertilizer applications. Explosives and propellants are hydrolyzed with a solution of ACTOSOL.RTM. humic acid extract. The humic acid extract fixes the free nitrogen evolved, preventing its loss as ammonia or NO.sub.x gases. The ACTOSOL.RTM. fixed nitrogen is then available directly to plants as slow-release nitrogen, and can directly replace nitrogen derived from urea or other sources in plant fertilizers., The carbonaceous material remaining from the denitrification process is non-explosive and is taken up in the humic acid matrix. This material is immediately available to plants as a carbon source. The humic acid matrix chelates any metal ions released from the explosive or propellant as a consequence of the denitrification process, and makes these metal ions available to plants as micronutrients.
