Hydrocarbon conversion process with catalytically active amorphous silica |
摘要 |
Catalytically active amorphous silicas are prepared by dehydrating a silica hydrogel or precipitate prepared from an acidified aqueous silicate solution containing an amine of pKa above 10 or a cation containing either a nitrogen or phosphorus atom bonded to four carbon atoms. The resultant amorphous silica is catalytically active for, among other chemical reactions, the isomerization of orthoxylene and the cracking of hydrocarbons.
