一般描述
三氧化硫 (SO 3 ) 是硫的氧化物。在含硫燃料燃烧过程中释放。在钒催化剂存在下，二氧化硫氧化生成三氧化硫。对该反应的动力学进行了研究。用密度泛函理论和从头算 方法研究了 SO 3 水解成硫酸的过程。
应用
三氧化硫 (SO 3 ) 可用于甲烷磺化合成甲磺酸 (MSA)。

Emissions of sulfur trioxide (SO3) are a key component of plume opacity and acid deposition. Consequently, these emissions need to be low enough to not cause opacity violations and acid deposition. Generally, a small fraction of sulfur (S) in coal

Sulfur emission from a Victorian brown coal was quantitatively determined through controlled experiments in a continuously fed drop-tube furnace under three different atmospheres: pyrolysis, oxy-fuel combustion, and carbon dioxide gasification conditions. The species measured were H(2)S, SO(2), COS, CS(2), and
