Skeletal catalysts were first discovered in the 1920s by Murray Raney [1,2], In recognition of their inventor, the catalysts are often referred to as Raney catalysts, although this trademark is now owned by the Davison division of W.R. Grace Co., who supply a range of catalysts for industrial use. Another common name is metal sponge, which refers to the porous structure of the catalysts. 

In New York state a reprocessing plant near Buffalo began to reprocess nuclear wastes in 1966. After 6 years Nuclear Fuel Services (NFS), a subsidiary of W.R. Grace s Davison Chemical Company, abandoned the facility. There were 2 million cubic feet of radioactive material left behind along with 600,000 gallons of radioactive liquid waste that was seeping into a creek that flows into Lake Erie the source of drinking water for Buffalo. The cost of cleanup was estimated to be 1 billion.

The authors are grateful to M. P. Shatlock for the solid state NMR spectra, B. J. Rees for the ESCA work and to the Davison Chemical Division of W. R. Grace Co.-Conn. for permission to publish this work. 

The FCC process is the most common conversion unit in use today. As such, it is important to determine the performance of an FCC when feeding hydrotreated shale oil. The two 650° F+ feeds shown in Table VI were evaluated in an FCC pilot plant operating in a fixed fluidized-bed mode. The catalyst was withdrawn from an operating commercial FCC unit. It is a zeolite catalyst, CBZ-1, produced by Davison Chemical Division of W. R. Grace and Company and is moderately active as well as contaminated with metals.
