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.

This invention relates to a cobalt-based catalyst on a metal structure for selective production of synthetic oil via Fischer-Tropsch reaction, a method of preparing the same and a method of selectively producing synthetic oil using the same, wherein zeolite, cobalt and a support are mixed and ground to give a catalyst sol, which is then uniformly thinly applied on the surface of a metal structure using a spray-coating process, thereby preventing generation of heat during Fischer-Tropsch reaction and selectively producing synthetic oil having a carbon chain shorter than that of wax. This catalyst is prepared by burning a powder mixture obtained by melt infiltration of a cobalt hydrate and a metal oxide support to give a catalyst powder including cobalt oxide/metal oxide support; hybridizing the catalyst powder including cobalt oxide/metal oxide support with a zeolite powder to give a hybrid catalyst powder; mixing the hybrid catalyst powder with an organic binder and an inorganic binder and grinding the mixed hybrid catalyst powder to give a hybrid catalyst sol; spray-coating a metal structure surface-treated with alumina by atomic layer deposition with the hybrid catalyst sol; and thermally treating the metal structure spray-coated with the hybrid catalyst sol.
