ACID GAS ADSORBENT

摘要

PROBLEM TO BE SOLVED: To develop an acidic gas adsorbent adsorbing a very small amt. of hydrogen chloride in thermally decomposed gas to almost perfectly removing the same, not deteriorated in its activity even after a long-term use period and easily replaced when capacity is lowered. SOLUTION: An acidic gas adsorbing adsorbent of a process of a method for producing petroleum oil from plastic is constituted so that 10-30 wt.% of alkali metal carbonate is supported on activated carbon and a benzene adsorbing amt. of benzene is 20-40 wt.% and a filling density is 0.40-0.60 g/ml. As an alkali metal carbonate, potassium carbonate is more pref. and this salt is more pref. in such a case that acidic gas in exhaust gas is hydrogen chloride.
