Synthetic, or carbonneutral, fuels capture CO₂ in the manufacturing process. In this way, this greenhouse gas becomes a raw material, from which gasoline, diesel, and substitute natural gas can be produced with the help of electricity from renewable sources. One further crucial advantage of the combustion engine using synthetic fuels is that ...

The Bergius process is a method of production of liquid hydrocarbons for use as synthetic fuel by hydrogenation of highvolatile bituminous coal at high temperature and pressure. It was first developed by Friedrich Bergius in 1913. In 1931 Bergius was awarded the Nobel Prize in Chemistry for his development of highpressure chemistry. [1] Process

The steady state design and economic evaluation for coal to synthetic natural gas (SNG) process is rigorously studied, and this study could give a baseline for design and analysis for SNG production in Taiwan or other countries relying on importation of an energy source. SNG is a product that holds very similar composition and heat value to typical natural gas, and can be used as a replacement ...

Abstract. To produce liquid fuels from coal, either direct or indirect liquefaction routes can be used. The discussion of the former route is the subject of Chapter 6; the latter route will be discussed here. The indirect liquefaction route consists of the conversion of coal to synthesis gas (hydrogen plus carbon monoxide), and then the ...

As shown in Fig. 1, the whole coalbased SNG process consists of three main sections: coal gasification, syngas processing (including water gas shift (WGS) unit and Rectisol unit), and methanation is fed into the gasifier and reacted with gasification agents from the air separation (AS) unit to produce crude syngas, which is then entered into the WGS unit to adjust the ratio of H/C.

The economic viability of producing synthetic natural gas (SNG) through coal gasification is heavily dependent on the market prices of natural gas and the coal feedstock to be used, in addition to the capital cost of the gasification plant.

The FischerTropsch process is a catalytic chemical reaction in which carbon monoxide (CO) and hydrogen (H 2) in the syngas are converted into hydrocarbons of various molecular weights according to the following equation: (2n+1) H 2 + n CO → C n H (2n+2) + n H 2 O. Where n is an integer. Thus, for n=1, the reaction represents the formation of ...

For example, it is possible to produce synthetic jet fuel, diesel, or gasoline for conventional planes, ships, trucks, and cars. The main difference between fossil and synthetic fuels is how they are produced: fossil fuels are formed over millions of years underground from organic matter that is turned into coal, natural gas, or oil.

The hybrid process couples features of both CTL and GTL, to decrease the amount of CO 2 emitted per kilogram of liquid fuel produced. In fact, part of the carbon dioxide produced by coal gasification and water gasshift reaction can be converted into syngas by dry reforming using methane.
