摘要:
Petroleum resid is upgraded in an improved process to produce a low pour point 650.degree.-775.degree. F. fraction without disturbing the product characteristics of other distillate boiling range fractions. The 650.degree.-775.degree. F. fraction is dewaxed separately from the remaining hydrodesulfurized product.
