PRODUCTION OF STORAGE MEDIUM USING HEAVY OIL ASH AND STORAGE MEDIUM

摘要

PURPOSE:To provide a method for producing a storage medium by using heavy oil ash as a raw material and to obtain a storage medium by this method. CONSTITUTION:Ammonium ion and sulfate ion of storage medium components contained in heavy oil ash are dissolved in water to give an aqueous solution of ammonium sulfate. The aqueous solution of ammonium sulfate is concentrated into an aqueous solution of an ammonium sulfate component having a melting point lower than ice and 40-80 Kcal heat of fusion. This is the method for producing the objective storage medium using heavy oil ash.
