Abstract: Cu/Silica gel
catalyst preparation by
using silica content
which is obtained
from Sabang natural crystobalit
has been done.
Isolated silica from
crystobalit is reacted
with natrium hidroxide to produce
silicate natrium that reacted further with sulphate acid to produce silica gel.
Silica gel is characterized by infra red spektroscopy dan BET test. BET test
result showed that silica gel obtained has specific surface area 260,04 m2/gram
and ion Cu2+ impregnation into
silica gel pores produce Cu/silica gel
catalyst with spesific
surace area 158,53 m2/gram with Cu2+ metal
content = 193 ppm. Catalyst activation test Cu/silica gel at
dehidrogenation reaction of etanol to
produce asetaldehide was done at temperature 100oC – 300oC.
Reseach showed that the
highest asetaldehide consentration
(20,24%) is obtained
at temperature 300oC.
Keywords: asetaldehide,
