Abstract: Methods and catalysts are provided for performing dewaxing of diesel boiling range fractions, such as trim dewaxing, that allow for production of diesel boiling range fuels with improved cold flow properties at desirable yields. In some aspects, the methods can include use of dewaxing catalysts based on an MEL framework structure (ZSM-11) to provide improved dewaxing activity. This can provide sufficient dewaxing activity to achieve a desired level of improvement in cold flow properties at the lower hydrotreating temperatures that are generally desired near the start of operation of a hydrotreating reactor. In other aspects, the methods can include use of MEL dewaxing catalysts with reduced ratios of molecular sieve to binder so that trim dewaxing can be provided while maintaining a desirable yield under end-of-run hydrotreating conditions.
