Comparing the results given in Tables 2 and 3, it can be seen that the raffinate oil extracted at 60[degrees]C can be saled as 20# heavy diesel and, on the other hand, the raffinate oil can be saturated after treatment in conditions of catalytic cracking, because nitrogen content in the raffinate oil meets the standard of catalytic cracking after solvent refining.
