Abstract

Solid acid nanoparticles are added to crude oil before initial distillation in order to increase the yield of light hydrocarbons obtained during initial distillation. According to one aspect, nanoparticles of a solid acid of a characteristic particle size are added to crude oil before initial distillation in order to increase the yield of light hydrocarbons obtained during initial distillation. According to another aspect, nanoparticles of a solid acid are added to crude oil in a characteristic concentration before initial distillation in order to increase the yield of light hydrocarbons obtained during initial distillation. According to another aspect, nanoparticles of two or more solid acids are mixed and added to crude oil before initial distillation in order to increase the yield of light hydrocarbons obtained during initial distillation.
