a unique process and catalyst is described that operates efficiently for the direct production of a high cetane diesel type fuel or diesel type blending stock from stoichiometric mixtures of hydrogen and carbon monoxide . this invention allows for , but is not limited to , the economical and efficient production high quality diesel type fuels from small or distributed fuel production plants that have an annual production capacity of less than 10 , 000 barrels of product per day , by eliminating traditional wax upgrading processes . this catalytic process is ideal for distributed diesel fuel production plants such as gas to liquids production and other applications that require optimized economics based on supporting distributed feedstock resources .
