A process and catalyst are suitable for hydroconverting heavy normal paraffins into lighter normal paraffin products with minimal formation of isoparaffins. The process and catalyst can be used on any feed that contains heavy normal paraffins such as waxy lubricant fractions, slack wax or Fischer Tropsch products. By selectively forming a normal paraffin rich product from heavy normal paraffins, the need for normal paraffin separation and purification processes can be reduced or eliminated.

A method for preparing 1 -adamantyltrimethylammonium hydroxide is disclosed. The method comprises reacting 1 -adamantyldimethylamine with dimethyl carbonate to produce 1 -adamantyltrimethylammonium methylcarbonate, which is then reacted with calcium hydroxide or magnesium hydroxide in the presence of water to produce 1 - adamantyltrimethylammonium hydroxide.
