This proposal is for research to determine the feasibility of a process to recover all of the metal and chemical valuesfrom spent petroleum hydrotreating catalyst in such a manneras to nearly eliminate any hazardous waste considerations. the critical steps in the process are (1) acid leach of the… More

Present technology for solvent recovery and recycle or for the solidification of hazardous liquid organic waste cannot be applied to all waste streams. materials containing corrosive, highly reactive, or acidic components are not compatible with the distillation/separation equipment of solvent… More

In november of 1984 the president signed into law a set of far-reaching amendments to the resource conservation and recovery act of 1976. under the new law, land disposal of all hazardous wastes is to be banned over the next five years. waste reduction, recycle, and incineration are emphasized.… More

About 28 million pounds of spent hydrotreating catalyst containing $23,000,000 in recoverable chemicals was dis posed of in the united states during 1985. only 20% of the spent catalyst underwent some form of reclamation process- ing. the amount of spent hydrotreating catalyst requiring disposal is… More

The production of halogenated organic compounds (hocs) and of chlorofluorocarbons (cfcs), in the united states, produces about 200 million pounds of refractory, hazardous waste per year. due to its low fuel value, corrosivity, andhazardous metals content, the waste is poorly suited for disposal by… More

The fluorocarbon industry in the united states currently generates over 1,200,000 pounds of spent antimony fluorocarbon catalyst annually in producing 1,190 million pounds of fluorocarbons (cfcs, hcfcs, hfcs). this spent catalyst is a mixture of halogenated organic compounds (hocs), antimony, and… More

The Phase II work will demonstrate at pilot scale the successful recovery of antimony and iodine values from spent perfluoroalkyliodide (PFAI) catalyst. The technical feasibility of this innovation and simple recovery process was demonstrated in Phase I. This recovery process was shown to be… More

Replacements for the halocarbons banned by the Montreal Protocol will be producedby technologies which generate spent catalysts as a waste byproduct. These spentcatalysts contain tin, a valuable metal resource, in a matrix that willundoubtedly be classified as hazardous with regard to its… More

Not Available In this Phase I proposal we outline a plan to develop a novel phase conjugate laser system capable of locking and tracking remote objects. The proposed system uses a pulsed laser with an intra-cavity four-wave mixing configuration. In this proposal we outline the operational… More
