An isomerization catalyst is provided, along with corresponding systems and methods, which provides improved isomerization for bio-derived feeds in reaction environments where by-products from deoxygenation are present. The catalyst provides unexpectedly increased activity and/or selectivity in situations where, for example, a deoxygenation effluent is cascaded to the isomerization catalyst. Additionally, the isomerization catalyst can assist with reducing or minimizing hydrogen consumption during isomerization. The increased activity, stability, and/or reduced hydrogen consumption is achieved in part based on using a dispersion agent when adding base metals to the catalyst. In addition to the base metals, the catalyst includes a zeolitic framework structure suitable for isomerization.
An isomerization catalyst, comprising a zeolitic framework structure, a binder, at least one first catalytic metal selected from Mo and W, and at least one second catalytic metal selected from Ni and Co, the zeolitic framework structure comprising MWW, MTW, FAU, FER, the framework structure corresponding to EMM-17, or a combination thereof, the catalyst comprising a combined weight of the at least one first catalytic metal and the at least one second catalytic metal of 1.0 wt % to 30 wt % relative to a weight of the catalyst, the catalyst having a ratio of metal layer locations comprising a single layer to metal layer locations comprising two layers of 1.1 or more.
