Abstract
A material for fixing gaseous hydrocarbon containing fibrous crystal aggregates formed by precipitating by making a metal aliphatic carboxylate dissolve completely in pure water to give a solution, stirring and gradually cooling the resulting solution; a method of preparing the fixing material; and a method of adsorbing and solidifying gaseous hydrocarbon by using the fixing material.
Claims8
A material for fixing gaseous hydrocarbon, which comprises fibrous crystal aggregates formed by precipitating by making a metal aliphatic carboxylate dissolve completely in pure water to give a solution, stirring, and gradually cooling the solution.
A material for fixing gaseous hydrocarbon, which comprises fibrous crystal aggregates formed by precipitating by making a metal aliphatic carboxylate dissolve completely in pure water to give a solution;
- adding an aqueous solution of an inorganic salt containing the same metal as in the metal aliphatic carboxylate;
- stirring;
- and gradually cooling the solution.
A method of preparing a material for fixing gaseous hydrocarbon, which comprises the steps of:
- making a metal aliphatic carboxylate dissolve completely in pure water to give a solution;
- stirring;
- and gradually cooling the solution, thereby precipitating as fibrous crystal aggregates.
