Sediment and colour formation is reduced in fuels containing more than 0.04 wt. % sulphur and 100 ppm nitrogen by the incorporation of small amounts of basic lithium, sodium, potassium or calcium compounds, this is particularly beneficial in fuels containing cracked components where the preferred additives are basic calcium or sodium compounds.
通过加入少量碱性
锂、
钠、
钾或
钙化合物,可减少含
硫量超过 0.04 重量%、含氮量超过 100ppm 的燃料中沉淀物和色素的形成,这对含有裂解成分的燃料尤其有益,因为裂解成分中的首选添加剂是碱性
钙或
钠化合物。
