초록

유기성 폐기물의 혐기성발효공정에 의한 바이오가스 연구가 다양한 목적으로 활발하게 진행되고 있다. 혐기성공정 또는 매립지에서 생성되는 바이오가스의 주요 조성은 메탄, 이산화탄소와 미량의 황화수소와 암모니아로 구성되며, 생산지에서 불순물을 정화시킨 후 바로 사용하거나 혹은 파이프라인을 통해 천연가스처럼 사용할 수 있다. 생산된 바이오가스는 열과 스팀생산, 전기생산, 자동차용 연료 및 화학물질 생산 등에 사용되어질 수 있다. 바이오가스는 사용 용도에 따라 여러 나라들의 관련 규정들이 정비되고 있지만 아직까지 국제적으로 공인된 표준 규격은 없다. 본 논문에서는 세계 각국의 바이오가스 용도별 품질특성을 살펴보았다.

The technology of anaerobic digestion of organic wastes has been researched for the production of biogas in various purposes. Biogas comes from anaerobic digestion and landfill in which that of main components are methane and carbon dioxide containing small amount of hydrogen sulfide and ammonia. Biogas can either be used directly on the site where it is generated after proper upgrading or distributed to external customer via separate pipelines like natural gas. There are four basic ways biogas can be utilized such as production of heat and steam, electricity production, vehicle fuel and production of chemicals. There is no international technical standard for biogas use but some countries have developed national standards and procedures for biogas use. In this paper, technical standards of biogas depending on purpose have reviewed for the several countries.
