A microemulsion is a mixture of water, oil, and an amphiphile (surfactant). This is a thermodynamically stable and optically isotropic solution. A microemulsion appears to be a homogeneous solution at the macroscopic level, but it is heterogeneous at the molecular level. The ratio of a microemulsion's components determines its internal structure at a given temperature. The internal structure of the microemulsion consists of minute oil droplets in a continuous water phase at high water concentrations (micelles). A bicontinuous phase with no clearly defined structure forms as oil concentration rises.
Catalytic cracking reduces the number of residuals and increases the quality and quantity of lighter, more desired products by breaking complicated hydrocarbons into simpler molecules.
