Abstract: Disclosed are fuel compositions for internal combustion engines comprising as a predominant component organic distillates which exhibit suitable physical properties, and a low-sulfur fraction of an alkylated petroleum feedstock which, for example, consisted of material boiling between about 60null C. and about 345null C. More particularly, compositions of the invention comprise low-boiling, low-sulfur, blending components, advantageously obtained by a process for converting sulfur-containing organic compounds which are unwanted impurities, to higher boiling products by alkylation and removing the higher boiling products by fractional distillation. Products can be used directly as transportation fuels and/or blending components to provide fuels which are more friendly to the environment.
