摘要：
A process is provided for improving cold flow properties of distillates, the process comprises the step of contacting a hydrocarbon feedstock with a framework-substituted ultra-stable Y (USY)-type zeolite in which a portion of aluminum atoms constituting a zeolite framework thereof is substituted with zirconium atoms and/or titanium and/or hafnium atoms, thereby producing a dewaxed distillate product.
