本文将最近引起世人瞩目的作为第二能源的煤炭利用技术,归纳为煤炭在能源中的地位、基本目标、重点开发课题以及每个课题的现状和将来的计划,以此作为国家能源的重点。一、煤炭利用技术的开发从石油危机以来,在能源构成变化的背景下,全世界对煤炭又重新重视起来。煤炭是日本主要国产能源资源。由于世界煤炭资源藏量丰富,为减少对石油过高的依赖性,煤炭就成为重要能源,因而期望进一步扩大煤炭的利用。目前石油是主要消费能源,如果改用煤炭代替石油,将固体的煤炭一成不变地用於各种工业部门和民 This paper summarizes the coal utilization technology as the second energy, which has attracted worldwide attention recently, as the status of coal in energy, the basic goals, the key development issues and the status quo and future plans of each issue as the focus of national energy. First, the development of coal utilization technology From the oil crisis, in the context of changes in the composition of energy, the world again pay attention to coal. Coal is Japan’s major domestic energy resource. Due to the abundant reserves of coal resources in the world, coal has become an important energy source in order to reduce the excessive dependence on oil. Therefore, it is expected that coal utilization will be further expanded. At present, oil is the main energy source of consumption. If coal is used instead of oil, solid coal will be used unchanged for various industrial sectors and people
