Figure 16. Predictions of the product yield: (a) naphtha; (b) diesel fuel; (c) tail oil. 

Figure 17 illustrates model predictions on the distillation curves of major products: naphtha, 

diesel fuel, and tail oil (in Dataset 1 and 2). Figure 18 shows the density predictions of three major 

products. The pinpoint predictions indicate the proposed method can well model the distillation 

curves and density predictions of major products.
