In Fischer-Tropsch synthesis (FTS), a variety of hydrocarbons with different chain lengths are formed. The selectivities depend on the catalyst and reaction conditions. Co-feeding olefins allows changing selectivity even outside rules Anderson-Schulz-Flory distribution. this work, ethene, propene, 1-butene were co-fed to Co-Mn-catalyzed FTS increase olefin in C3- C8-fraction. An CO rate oxygena...

This contribution is based on the monograph entitled “Recent Advances in Thermochemical Conversion of Biomass”, covering both general items as well as the primary processes, like fast pyrolysis, gasification, hydrothermal liquefaction, carbonization and secondary processes, like co-processing of bio-oil in fluidized catalytic cracking (FCC), Fischer-Tropsch synthesis and valorization of lignin ...

Pd/C and CoPd/C heterogeneous catalysts have been synthesized by adopting Charge Enhanced Dry Impregnation (CEDI). The particles size distribution, their high metal surface-to-bulk ratios, and synthesis feasibility are unmatchable to any known noble metal bimetallic heterogeneous catalyst preparation techniques. Next generation Fuel Cells and Fischer-Tropsch catalytic processes economy will be ...

the effects of confinement in carbon nanotubes on fischer-tropsch (ft) activity, selectivity and lifetime of carbon nanotubes (cnts) supported iron catalysts are reported. a method was developed to control the position of the catalytic sites on either inner or outer surface of carbon nanotubes. tem analyses revealed that more than 80% of iron oxide particles can be controlled to be positioned a...

The aviation industry contributes to more than 2% of global human-induced CO2-emissions, and it is expected increase 3% by 2050 as demand for grows. As the still dependent on conventional jet fuel, an essential component a carbon-neutral growth low-carbon, sustainable fuels, example alternative drop-in fuels with biobased components. An optimization model was developed case Sweden examine impac...

One possible origin of prebiotic organic material is that these compounds were formed via Fischer-Tropsch-type (FTT) reactions of carbon monoxide and hydrogen on silicate and oxide grains in the warm, inner-solar nebula. To investigate this possibility, an experimental system has been built in which the catalytic efficiency of different grain-analog materials can be tested. During such runs, th...

We present in situ experiments to study the possible formation of cobalt carbides during Fischer–Tropsch synthesis (FTS) a Co/TiO2 catalyst at relevant conditions pressure and temperature. Th...

Fischer−Tropsch synthesis (FTS, CO + H 2 → long-chain hydrocarbons) for its great significance in the industry has attracted huge attention since discovery. For Fe-based catalysts, after decades of...

The aim of this work is to select the best individual or combined controlled variables (CVs) for a natural gas to hydrocarbon liquids (GTL) process based on the idea of self-optimizing control. The objective function is to maximize the variable income of the plant, and two modes of operation are studied. In mode I, where the natural gas flow rate is given, there are three unconstrained degrees ...
