Consider catalytic dewaxing as a tool to improve diesel cold-flow properties

Diesel engines rely on effective dispersion of fuel to ensure efficient combustion. In cold weather regions, maintaining the fluidity flow of fuels can be difficult. Catalytic dewaxing is a selective hydrocracking process that provides a valuable improvement to low temperature performance of middle distillate feedstocks. It greatly improves cloud point (CP) and cold-filter plugging point (CFPP) properties of diesel fuels. Background At present, most US refineries are optimized for the production of gasoline, i.e., fluid catalytic cracking (FCC) units. With the growing interest in diesel-powered passenger cars, existing refineries will not be able to serve that new demand for clean
