Abstract

PURPOSE: To obtain silicic acid hydrate having high oil adsorbing speed and superior adsorbing power and free from formation of fine coal in handling by slurrying a wet cake of silicic acid hydrate obtd. by adding acid to an aq. alkali silicate soln. in two steps under specified conditions and by spray-drying the slurry.
CONSTITUTION: When acid is added to an aq. alkali silicate soln. in multiple steps reacted, filtered, and dried to manufacture silicic acid hydrate, the reaction is performed while adjusting the ratio (A) of the amt. of the acid added in the first step to the total amt. of the acid added to 20W50%, the concn. (C) of silica in the soln. at the second step acid addn. to 2W6g/100cc and the reaction temp. (T) to 70W100°C under conditions which make the value (X) of the equation 1.28W1.55. The resulting liquid reactant is filtered to obtain a wet cake of silicic acid hydrate. By applying shearing force or vibration this cake is slurried and spray-dried to obtain silicic acid hydrate in which pores of 150Å or less occupy a vol. of 0.5cc/g or more in pore diameter distribution, and grains of 149W500μ diameter occupy 45% or more.
