The present invention relates to a process for converting Fischer-Tropsch wax to high quality lube basestocks using a molecular sieve Beta catalyst followed by a unidimensional intermediate pore molecular sieve with near circular pore structures having an average diameter of 0.50 nm to 0.65 nm wherein the difference between the maximum diameter and the minimum is &#x2266;0.05 nm. Both catalysts comprise one or more Group VIII metals. For example, a cascaded two-bed catalyst system consisting of a first bed Pt/Beta catalyst followed by a second bed Pt/ZSM-48 catalyst is highly selective for wax isomerization and lube hydrodewaxing with minimal gas formation.

A method is provided for co-producing dialkyl carbonate and alkanediol by reacting alkylene carbonate with alkanol in the presence of an amorphous aluminosilicate catalyst containing alkali metal, alkaline earth metal, or a combination thereof.

Process for co-production of dialkyl carbonate and alkanediol

A method is provided for co-producing dialkyl carbonate and alkanediol by reacting alkylene carbonate with alkanol in the presence of a Group 5 or Group 6 metal oxide catalyst.

A method is provided for co-producing dialkyl carbonate and alkanediol by reacting alkylene carbonate with alkanol in the presence of a complex salt catalyst having a formula A.sub.x (M.sub.y O.sub.z), wherein A is an alkali metal or alkaline earth metal, M is a Group 5 or Group 6 transition metal, O is oxygen, x is 1 or 2, y is 1 or 2, and z is an integer from 3 to 6.
