Modelling reaction and diffusion in a wax-filled hollow cylindrical pellet of Fischer Tropsch catalyst

Separation of Fischer-Tropsch Wax from Catalyst by Supercritical Extraction

Conversion in Chemical Reactors using Hollow Cylindrical Catalyst Pellet

Heterogeneous catalysis is vital for a number of chemical, refinery and pollution control processes. The use of catalyst pellets of hollow cylindrical shape provide several distinct advantages over other common shapes, and can therefore help to enhance conversion levels in reactors. A better utilization of the catalytic material is probably most notable of these features due to the absence of t...

The optimally performing Fischer-Tropsch catalyst.

Microkinetics simulations are presented based on DFT-determined elementary reaction steps of the Fischer-Tropsch (FT) reaction. The formation of long-chain hydrocarbons occurs on stepped Ru surfaces with CH as the inserting monomer, whereas planar Ru only produces methane because of slow CO activation. By varying the metal-carbon and metal-oxygen interaction energy, three reactivity regimes are...

Aqueous-phase Fischer-Tropsch synthesis with a ruthenium nanocluster catalyst.

Introduction Hydrogenation of carbon monoxide to produce hydrocarbons, normally called Fischer-Tropsch synthesis (F-T synthesis), is one of the most important hydrogenation reactions due to its potential for the intermediate production of hydrocarbon fuels in the “postpetroleum” era. The reaction is favored at low-temperature and therefore reducing the particle size of the catalyst to several n...
