SPAC-1 Solid Phosphoric Acid Catalyst
SPAC-1 is the latest generation solid phosphoric acid catalyst researched,
developed and produced by Shenyang hi-tech science and technology development
Co.,Ltd. adding special component , it possesses better activity, selectivity,
crushing strength, mudding-resistance and long-lifetime, etc.
SPAC-1 is mainly used in the polymerization from propylene into alkene that
the number of carbon atom are nine or twelve. It also can be used in the process of
butene polymerizing into the alkene that the number of carbon atom are from eight
to sixteen, the butene polymerizing into high octane number gasoline, iso-butene
double polymerizing into iso-octane, and benzene reacting with propylene into iso-propyl
benzene, etc.
