The present invention is a method for removing sulfur from liquid hydrocarbon feedstocks and for performing hydrogenation reactions in sulfur-contaminated feedstocks, including the hydrogenation of naphthalene in the presence of sulfur compounds, using catalysts or adsorbents comprising metal oxide nanowires decorated with reduced catalytically-active metal particles. In a preferred embodiment, the adsorbent comprises zinc oxide nanowires decorated with catalytically-active metals selected from nickel, cobalt, molybdenum, platinum, palladium, copper, oxides thereof, alloys thereof, and combinations thereof. In some embodiments, the sulfur is removed through a desulfurization process without an external hydrogen supply. The process is effective for the removal of sulfur from diesel fuels and liquid fuel streams, and for deep desulfurization of natural gas streams. The process is also effective for the selective hydrogenation of naphthalene to tetralin in the presence of sulfur compounds.

Desulfurization and sulfur tolerant hydrogenation processes of hydrocarbon feedstocks

The present development is a process to produce commodity chemicals such as methanol and syngas using an integrated plasma catalysis technology. The method comprises providing a fixed or fluidized bed reactor having a microwave plasma flame and a catalyst bed with a catalyst, wherein the catalyst is an alloyed bimetallic nanowire. In the process, the plasma flame fluidizes the catalyst thereby producing a more effective catalyst than the non-fluidized catalyst. It is anticipated that the reactor can have a throughput capacity of up to 30 Lpm/kW and can be effective for the conversion of CO, CH, air, water, and combinations thereof, through reactions such as pure COsplitting, reverse water gas shift (RWGS) for CO production, methanol synthesis, and plasma reforming of methane, thereby making a system that would be attractive for small GTL units.

Plasma assisted distributed chemical production

The present development is a method for the selective conversion of furfural to 2-methylfuran (2-MF) using a catalyst comprising non-toxic and non-noble metals and wherein the method requires relatively mild processing conditions. The catalyst comprises copper metal particles, used alone or in combination with cobalt, nickel, manganese, ruthenium, gallium, zinc, aluminum or a combination thereof, on a nanowire support. The catalyst is stable in liquid phase reactions and in the presence of water. The present development also includes a process for producing the catalyst.

Catalyst compositions for conversion of furfural to 2-methylfuran and their applications

The present development is a metal particle coated nanowire catalyst for use in the hydrodesulfurization of fuels and a process for the production of the catalyst. The catalyst comprises titanium(IV) oxide nanowires wherein the nanowires are produced by exposure of a TiO&#x2014;KOH paste to microwave radiation. Metal particles selected from the group consisting of molybdenum, nickel, cobalt, tungsten, or a combination thereof, are impregnated on the metal oxide nanowire surface. The metal impregnated nanowires are sulfided to produce catalytically-active metal particles on the surface of the nanowires The catalysts of the present invention are intended for use in the removal of thiophenic sulfur from liquid fuels through a hydrodesulfurization (HDS) process in a fixed bed reactor. The presence of nanowires improves the HDS activity and reduces the sintering effect, therefore, the sulfur removal efficiency increases.

Nanowire-based hydrodesulfurization catalysts for hydrocarbon fuels

The present invention relates to the use of adsorbents comprising zinc oxide nanowires decorated with catalytically active metal particles for the removal of sulfur from hydrocarbon feedstocks, including the desulfurization of diesel fuels and the deep desulfurization of natural gas, and to the use of decorated zinc oxide nanowire adsorbents for the hydrogenation of naphthalene selectively to tetralin in the presence of sulfur compounds. The adsorbent comprises nickel metal particles or nickel-zinc alloy particles deposited on zinc oxide nanowires.
