Abstract
The invention relates to a process for the catalytic dewaxing of a hydrocarbon feed containing waxy molecules by contacting the hydrocarbon feed under catalytic dewaxing conditions with a catalyst composition having metallosilicate crystallites, a binder and a hydrogenation component, wherein the weight ratio of the metallosilicate crystallites and the binder is between 5:95 and 35:65. The invention also relates to a catalyst composition having at least a low acidity refractory oxide binder, which binder is essentially free of aluminum, metallosilicate crystallites and a hydrogenation component, wherein the weight ratio of the metallosilicate crystallites and the binder is between 5:95 and 35:65.
