This study comprises the dynamic process simulations of a HTW gasification plant for Fischer-Tropsch (FT) liquids production under transient feedstock lignite and solid recovered fuel (SRF) as well load variations. Main objective current is proof concept in unsteady conditions effective wide control novel gasification-driven liquid fuels pathway. Therefore, analysis all sub-units an integrated ...

Water increases Fischer-Tropsch synthesis (FTS) rates on Ru through H-shuttling processes. Chemisorbed hydrogen (H*) transfers its electron to the metal and protonates the O-atom of CO* to form COH*, which subsequently hydrogenates to *HCOH* in the kinetically relevant step. H2 O also increases the chain length of FTS products by mediating the H-transfer steps during reactions of alkyl groups w...

Converting coal or natural gas into synthetic crude oil (Fischer-Tropsch method) is a costly and difficult undertaking associated with long development timeframes of up to a decade or longer, which may no longer be available (Hirsch, 2006). It would also result in a net increase in carbon emissions unless carbon is captured and geo-sequestered. This technology remains untried, would be financia...

The interest in Gas-to-Liquid technology (GTL) is growing worldwide because it involves a two-step indirect conversion of natural gas to higher hydrocarbons ranging from Liquefied Petroleum Gas (LPG) paraffin wax. GTL makes possible obtain clean diesel, naphtha, lubes, olefins, and other industrially important organics gas. This article brief review discussing the state-of-the-art GTL, includin...

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...

Identifying the structure sensitivity of catalysts in reactions, such as Fischer-Tropsch synthesis from CO and H2 over cobalt catalysts, is an important yet challenging issue in heterogeneous catalysis. Based on a first-principles kinetic study, we find for the first time that CO activation on hexagonal close-packed (HCP) Co not only has much higher intrinsic activity than that of face centered...
