A flexible combined heat, power and fuel production concept, FlexCHX, is being developed for managing the seasonal mismatch between solar energy supply demand heat characteristic of northern central Europe. The process produces an intermediate carrier (Fischer-Tropsch (FT) hydrocarbon product), which can be refined to transportation fuels using existing refineries. FlexCHX integrated into vario...

Taking the importance of Pakistan’s dire need for energy breakthrough, in this paper, we explore how country’s vast estimated reserves 175 billion tons Thar coal is a useful source clean and efficient production good quality liquid fuel. Coal to (CTL) technology has gathered increasing attention among many countries with sufficient volume reserves, can also be implemented Pakistan, which result...

A well-known observation in the Fe-catalyzed Fischer-Tropsch (FT) reaction is that Fe-carbide catalysts deactivate due to carbon deposition. In comparison, influence of such deposits on product distribution has been less widely reported. The present work investigates relationship between kinetics FT for a carburized Raney-Fe model catalyst and composition catalytic surface with focus deposits. ...

General aviation aircraft driven by piston engines (APE) have gained a broad range of applications. Aviation fuels blended with long-chain alcohols is promising means for APE to mitigate its dependency on fossil fuel. Herein, the combustion and emission characteristics an compression ignition engine burning baseline diesel, RP-3 kerosene, synthetic Fischer-Tropsch (FT) fuel were analyzed. The t...

The recent rise in crude oil price forces us to look for alternative energy sources. The most sensible direction of this search is natural gas upgrading to liquid hydrocarbons via a mixture of carbon monoxide and hydrogen (syngas). Hydrogenation of CO to liquid hydrocarbons has been known since 1923 as Fischer-Tropsch synthesis (FTS). Great R&D efforts have been made all over the world to devel...

Large-scale biofuel production plants require an efficient gasification process that generates syngas of high quality (with minimal gas contaminants and inert gases) to minimize the extent cleaning processes required for liquid production. This work presents modeling chemical looping (CLG) The CLG is integrated with a Fischer–Tropsch synthesis (FTS) produce (FT) crude net-negative CO2 emissions...

Nano-structure of Co–Mn spinel oxide was prepared by thermal decomposition method using [Co(NH3)4CO3]MnO4 as the precursor. The properties of the synthesized material were characterized by X-Ray Diffraction (XRD), Brunauer-Emmett-Teller (BET), Transmission Electron Microscopy (TEM), surface area measurements, Energy-Dispersive X-ray (EDX) spectroscopy analys...

The separation and recycling of effective resources in Fischer-Tropsch wax residue (FTWR) are urgent because the environmental hazards energy waste they bring. In this study, organic solvents used to separate recyclable from FTWR efficiently, achieving goals “Energy Recycle” “Fisher-Tropsch Wax Residue Treatment”. response surface methodology (RSM) analysis model accurately evaluates relationsh...

Fischer-Tropsch (FT) synthesis produces an aqueous stream containing light oxygenates as major by-product. The low carbon concentration of the organics makes its thermal recovery unprofitable. Thus, novel processes are needed to utilize this waste content. In work, phase reforming wastewater obtained from a 15 kWth plant was explored promising process produce hydrogen at mild temperatures. FT p...

A model Co/SiO2 catalyst was prepared by depositing cobalt on silica films in ultrahigh vacuum conditions. Fischer–Tropsch synthesis was carried out at a total pressure of carbon monoxide and hydrogen between 0.33 and 1.0 bar. The effects of reaction temperature and pressure on kinetics and chain growth probability were investigated. The turnover frequency, activation energy, and product distri...
