Abstract
PURPOSE: To manufacture a highly active silica-alumina catalyst having noncrystal property, a small specific surface, a high activity, and a high selectivity by heating an aqueous raw material mixture containing a silica source, an alumina source, a free hydroxide source, and a trimethylammonium compound.
CONSTITUTION: An aqueous raw material mixture, containing a silica source, e.g., silica powder, silicic acid, etc., an alumina source, e.g., Al2(SO4)3, alum, etc., an inorganic salt as a free hydroxide source, e.g., KOH, Mg(OH)2, etc., a trimethylammonium compound, and water in proportions of SiO2/Al2O3=1W200, OH-/ SiO2=0.01W0.5, H2O/SiO2=10W100, and R2O/Al2O3=0.1W3.0 (R is trimethylammonium), is heated at 80W250°C for 5hrs to 50 days and filtered to obtain silica- alumina hydrates, and the silica-alumina hydrates are washed with water, dried at 50W150°C for 1W100hrs, and lastly baked at 250W900°C for 1W50hrs.
