  • Publication number: 20070142213
    Abstract: A process for regenerating a used acidic catalyst which has been deactivated by conjunct polymers by removing the conjunct polymers so as to increase the activity of the catalyst is disclosed. Methods for removing the conjunct polymers include hydrogenation, addition of a basic reagent and alkylation. The methods are applicable to all acidic catalysts and are described with reference to certain ionic liquid catalysts.

  • Publication number: 20070032692
    Abstract: 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.
