Some catalytic properties of silica-supported base and metal porphyrins
for hydrocarbon cracking and hydrogenation
Caga, I T; Carnell, I D; Winterbottom, J M
Journal of Chemical Technology and Biotechnology; 76 (2) Feb 2001,
A base porphyrin, etioporphyrin (EPI), was synthesized and a number
of metal-etioporphyrin compounds were derived from EPI by metal
insertion, these being nickel, vanadyl, palladium and platinum.
The metal-etioporphyrins were supported on silica gel with various
loadings to be employed as catalysts for hydrocarbon cracking
and to a minor extent for hydrogenation. The porphyrins themselves
were characterized using temperature programmed decomposition
(TPD), temperature programmed reduction (TPR), mass spectroscopy
(MS) and infra-red (IR) spectroscopy. TPD studies up to 550C indicated
complete stability and TPR studies (20-500C) showed interaction
with hydrogen, nickel-EPI and Pd-EPI especially showing strong
interaction. (Original abstract - amended)
