| 摘 要： | 媒中硫的含量大都由煤层的沉积环境控制，并取决于成煤物质是否曾受过海水影响及其受海水影响的程度。煤中硫的含量对于煤的有效利用甚为重要。这主要是因为燃煤时有相当量的二氧化硫释放到大气中造成对环境有害的酸雨。因此，煤层中硫的分布和地质特征是评估煤的品质及解决有关环境问题的一个重要参数。洁净煤技术是为了有效解决能源需求并减少用煤对环境的影响而发展起来的。它包括煤燃烧前的洁净方法（物理、化学和微生物的煤洁净法）、烟气脱硫、吸附剂喷撒和各种媒燃烧技术（流化床、气化联合循环等）。

| Abstract: | The abundance of sulfur in coal is largely controlled by sedimentary environments during coal formation.It depends on whether the parent materials of coal were ever influenced by seawater during the history of coal formation and the intensity of seawater influence.The sulfur content in coal is important to effective coal utilization because coal combustion causes release of a substantial amount of sulfur dioxide to the atmosphere and ensuing environmentally hazardous caid rain.Therefore,the distribution of sulfur and its geologic characteristcs are important indicators in evaluating coal quality and in solving related environmental problems.The clean coal technologies are developed for effective utilization of coal resources with a minimum impact on the environment.Such technologies include procombustion techniques(physical,chemical,and microbial coal cleaning),flue gas desulfurization,sorbent injection,and various coal combustion technologies(fluidized-bed combustion,integrated gasification combined cycle,etc.) |
