内容記述 |
The dioxin from the arbage incineration is one of the most serious environmental problems in recent years. There is a method using calcium hydroxide [CaCOH)2] as one of the dioxin preventive methods, reacting in the present garbage incineration and removing the chlorine in combustion exhaust gas. The formation mechanism of specific surface in the calcium hydroxide powder generated by reaction from quicklime is not sufficiently elucidated up to now. Calcium hydroxide was thought to decrease specific surface area until now in the case where carboxylic acid is used as an addition in calcium hydroxide reaction. In this paper, the applicability of carboxylic acid to calcium hydroxide reaction, and the morphology formation mechanism of the specific surface of calcium hydroxide is experimentally discussed. As a result, a new triple product factors of the alkyl chain length of the added carboxylic acid, the acidity and the interaction between carboxylic acid and water, were successfully introduced to be reasonably described the experimental result between specific surface area and amount of acid. And, the optimum alkyl chain ength was experimentally pointed out to exist at 5 showing the maximum specific surface area of calcium hydroxide. Also, the increment effect to specific surface area by carboxylic acid addition was shown to be maximum at 0.05 of the amount of carboxylic acid. |
