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 de­ sired level of improvement in cold flow properties at the lower hydrotreating temperatures that are gener­ ally desired near the start of operation of a hydro - treating reactor. In other aspects, the methods can in­ clude use of MEL dewaxing catalysts with reduced ratios of molecular sieve to binder so that trim dewaxing can be provided while maintaining a desir­ able yield under end-of-run hydrotreating conditions. n o WO 2017/112558 A1 LV, MC, MK, MT, NL, NO, PL, PT, RO, RS, SE, SI, SK, SM, TR), OAPI (BF, BJ, CF, CG, CI, CM, GA, GN, GQ, GW, KM, ML, MR, NE, SN, TD, TG).
