Title:
硫化水素除去のために使用された窒素処理炭素質炭の再生方法
Document Type and Number:
Japanese Patent JPH09510912
Kind Code:
A
Abstract:
A process is provided for the restoration of hydrogen sulfide removal capacity in nitrogen-treated carbonaceous chars which have become exhausted for hydrogen sulfide capacity when used for the removal of hydrogen sulfide from gas streams containing oxygen and water. This process entails washing the spent carbonaceous char with water of sufficient quantity to remove the majority of the hydrogen sulfide reaction products. By the use of this process a significant proportion of the original hydrogen sulfide capacity of the nitrogen-treated carbonaceous char is recovered.
