Progress in developing a new class of support materials based on silicon carbide
(SiC)is reviewed. Silicon carbide has superior mechanical and thermal properties
which, coupled to chemical inertness,avoids several of the problems inherent in
the use of commercial oxide and carbon based supports and catalysts. High
surface area SiC can now be prepared easily in a commercially viable shape,with

The use of supercritical fluids (SCFs) in technology and research has been
triggered by several unique features of these media. SCFs allow improvement of
technical processes such as extraction, separation, particle formation and
chemical reactions. However, it has been just in the last decades that SCFs have
gained their importance in science and industrial applications, due to the
relatively high... hiện toàn bộ
