The Fischer-Tropsch synthesis is a catalytic process that can produce a fuel similar to fossil fuels by using primary sources such as agricultural waste and carbon sources that can convert into synthesis gas by superheated steam. All fuel derivatives can be supplied through the Fischer-Tropsch reaction. The synthesis produces a variety of hydrocarbons via parallel and sequential reactions. Howe...

in this paper, modeling and optimization of fischer-tropsch synthesis is considered in a fixed-bed catalytic reactor using an industrial fe-cu-k catalyst. a one dimensional pseudo-homogenous plug flow model without axial dispersion is developed for converting syngas to heavy hydrocarbons. the effects of temperature, pressure, h2 to co ratio in feed stream, and co molar flow on the mass flow rat...

accelerated deactivation of co/al2o3 catalysts in fischer-tropsch synthesis and the effect of re and ru as the catalytic promoters are reported. 15wt% co/al2o3 catalyst and 1wt% ru and 1.4wt% re  promoted cobalt catalysts have been formulated and extensively characterized. the deactivation of the unpromoted cobalt catalyst and those promoted with re and ru were studied by accelerated method at ...

An FT-IR Spectrometer is an instrument which acquires broadband NIR to FIR spectra. Unlike a dispersive instrument, i.e. grating monochromator or spectrograph, an FT-IR Spectrometer collects all wavelengths simultaneously. This feature, called the Multiplex or Felgett Advantage, is discussed in detail on page 3. FT-IR Spectrometers are often simply called FT-IRs. But for the purists, an FT-IR (...

The potential of carbon nanotubes (CNT) supported cobalt catalysts for Fischer-Tropsch (FT) reaction is shown. Using the wet impregnation method cobalt on carbon nanotubes catalysts were prepared with cobalt loading varying from 15 to 45 wt. %. The catalysts are characterized by different methods including: BET physisorption, X-ray diffraction, hydrogen chemisorption, and temperature-progra...

The discovery of the catalytic synthesis of ammonia must rank as one of the important discoveries by mankind. In addition to providing the fertilizer needed to feed an expanding population, Fritz Haber’s recognition of recycle processing combined with the developing German technology to handle high pressures of hydrogen, led a major revolution in the chemical industry. In rapid succession, the ...

The reduction, carburization, and catalytic properties of Fischer-Tropsch synthesis (FTS) catalysts based on Fe-Cu were examined using kinetic and spectroscopic methods at reaction conditions. Fe2O3 precursors reduce to Fe3O4 and then carburize to form a mixture of Fe2.5C and Fe3C in both CO and H2/CO mixtures at 540-720 K. Oxygen removal initially occurs without FTS reaction as Fe2O3 forms ina...
