Hydrocracking was first applied in the early 1960s to convert low-value distillate feeds such as cycle oils and heavy gas oils to high-value gasoline products (3). In the 1970s, a broader range of hydrocracking products were targeted in order to address the shifting market demand toward turbine (jet) fuel and diesel fuels.
