A cable comprising one or more electrical conductors or communications media or a core of two or more electrical conductors or communications media, each electrical conductor, communications medium, or core being surrounded by a layer comprising:

Cable semiconducting shield

Semiconducting shield compositions

Carbon and catalyst containing chars obtained from a catalytic coal gasification or combustion operation may be separated into two layers of fractions by contacting them with an inert gas so as to fluidize them and thereby separately recover fractions of carbon-rich chars and fractions of carbon-poor chars, and collecting the separate fractions. The carbon-rich chars may then be recycled to the gasifier to be gasified, and the carbon-poor chars may be treated to recover the catalyst. Larger catalyst containing chars may be effectively separated in the presence of a host medium of a bed of solids fluidized by the inert gas. Smaller chars may be separated in the absence of such a host medium.

Process for separating catalytic coal gasification chars

This invention relates to an apparatus or means for improving solid and fluid handling and distribution in magnetically stabilized fluidized beds. These devices decouple the solids and fluid flows in a buffer zone at the fluid introduction or withdrawal points in a bed and therefore achieve good radial fluid mixing otherwise lacking in such fluidized beds.
