It has been surprisingly discovered that reaction with hydrogen over a Re-containing multimetallic catalyst resulted in superior conversion and selectivity to desired products such as propylene glycol.Type: GrantFiled: October 23, 2001Date of Patent: January 11, 2005Assignee: Battelle Memorial InstituteInventors: Todd A. Werpy, John G. Frye, Jr., Alan H. Zacher, Dennis J. Miller

Patent number: 6797191Abstract: A method for reducing the drag on an aqueous solution in a pipe or hose system such as a snow making system includes the introduction of drag reducing polymers into the aqueous solution prior to circulating the solution in a pipe or hose. In a preferred embodiment, the drag reducing polymers are a mixture of polyethylene oxide in a carrier solution. The introduction of the polyethylene oxide in a carrier solution reduces the overall frictional drag and therefore increases the snow making efficiency by reducing the power needed to pump the water. As a result, it is easier for greater quantities of snow to be made using existing equipment due to the increased flow rate as a result of the lower drag friction. In a preferred embodiment, the polyethylene oxide is approximately 20-30% by weight and is introduced into the water pipe so resulting concentrations are approximately 30-100 weight parts per million (WPPM).Type: GrantFiled: February 28, 2002Date of Patent: September 28, 2004Assignee: The United States of America as represented by the Secretary of the NavyInventors: Richard B. Philips, Theresa A. Baus
