Fossil fuels naphtha

A high-nickel alloy is used for increased strength at elevated temperature, and a chromium content in excess of 20% is desired for corrosion resistance. An optimum composition to satisfy the interaction of stress, temperature, and corrosion has not been developed. The rate of corrosion is directly related to alloy composition, stress level, and environment. The corrosive atmosphere contains chloride salts, vanadium, sulfides, and particulate matter. Other combustion products, such as NO, CO, CO2, also contribute to the corrosion mechanism. The atmosphere changes with the type of fuel used. Fuels, such as natural gas, diesel 2, naphtha, butane, propane, methane, and fossil fuels, will produce different combustion products that affect the corrosion mechanism in different ways. 

Hydrogen production from fossil fuels is based on steam reforming of natural gas, thermal cracking of natmal gas, partial oxidation of heavier than naphtha... 

The development of high-purity hydrogen production/supply system utilising fossil fuels such as natural gas/LPC/methanol/naphtha, etc. by 2012. 

Hydrogen can be generated from a variety of sources fossil fuels such as natural gas, naphtha, fuel oils, coal renewable fuels such as landfill gas and water by electrolysis. Generating hydrogen from fossil fuels is viewed as a transitional strategy on the pathway to an environmentally responsible, sustainable energy economy (DOE, 1998). 

The use of Fe-Cr and especially Cu-Zn-Al WCS catalysts in present-day hydrogen plants is directly connected with moderate levels of sulfur-containing compounds in natural gas and naphtha that almost completely displaced coal as the feedstock. It is likely, however, that the incentives for the use of fossil fuels rich in sulfur can be revitalized in the future. If this scenario comes into play, sulfur-tolerant catalysts will be a must for WCS process. Such catalysts are already developed, but so far they have only found a limited use in some particular cases where feed gases with high concentrations of CO and sulfur compounds had to be converted. The best known of this type are cobalt-molybdenum compositions, which are usually supported over alumina and may be promoted with alkali... 

Today the feedstock for ethylene is different fossil fuel streams such as ethane, propane, butane and naphtha. They are obtained as products from natural gas processing and petroleum refining. However, the total production of chemicals based on fossil fuel streams only consumes a small fraction compared to energy and transportation. On a global basis approximately 3% of the oil and gas market is used for chemical production. This corresponds to approximately 1% of the global energy consumption. Over the years...
