Title: TRIMETALLIC BASE METAL HDN+HDS+DEWAXING CATALYSTS, THEIR PREPARATION AND USE
Abstract:
Methods, catalysts, and corresponding catalyst precursors are provided for performing dewaxing of diesel or distillate boiling range fractions. The dewaxing methods, catalysts, and/or catalyst precursors can allow for production of diesel boiling range fuels with improved cold flow properties at desirable yields. The catalysts and/ or catalyst precursors correspond to supported base metal catalysts and/or catalyst precursors that include at least two Group 8 - 10 base metals supported on the catalyst, such as a catalyst/catalyst precursor including both Ni and Co as supported metals, along with a Group 6 metal (i.e., Mo and/or W). The support corresponds to a support including a zeolitic framework structure. The catalyst precursors can be formed by impregnating a support including a zeolitic framework structure with an impregnation solution that also includes a dispersion agent.
