The sulfur found in coal stems in large part from sulfur incorporation at the peat-forming stage. Ester sulfate (a carbon-oxygen-sulfur linkage) is a major contributor to the sulfur in peat and thus is an important determiner of the quantity and forms of sulfur eventually found in coal.
煤中的硫大部分来源于泥炭形成阶段的硫掺入。硫酸酯（碳-氧-硫键）是泥炭中硫的主要贡献者，因此是最终在煤中发现的硫的数量和形态的重要决定因素。
