The reasons for the choice of energy sources are many. There is a need to know the options available and how to exploit them, the need to harness some of these sources efficiently and effectively and above all the environmental concerns these energy sources give rise to. The standard of living of the people of any country is considered to be proportional to the energy consumption by the people of that country. In one sense, the disparity one feels from country to country arises from the extent of accessible energy for the citizens of each country. Unfortunately, the world energy demands are mainly met by the fossil fuels today. The geographical non equidistribution of this source and also the ability to acquire and also control the production and supply of this energy source have given rise to many issues and also the disparity in the standard of living. The scene of energy resources have been visualized in terms of various parameters. Mainly the population increase and also the need to increase the standard of living are the factors forcing to see new and alternate energy options. The climate change which is threatening the existence of life is another factor forcing to consider alternate energy sources. However, the energy sources to be adopted will have to meet the varying needs of different countries and at the same time enhance the security of each one against the energy crisis or energy shortage that have taken place in the past. Petroleum is oily, flammable, thick dark brown or greenish liquid that occurs naturally in deposits, usually beneath the surface of the earth; it is also called as crude oil. Petroleum means rock oil, the name inherited for its discovery from the sedimentary rocks. It is used mostly for producing fuel oil, which is the primary energy source today. Petroleum is also the raw material for many chemical products, including solvents, fertilizers, pesticides and plastics. A catalytic reforming process converts a feed stream containing paraffins, olefins and naphthenes into aromatics to be used either as a motor fuel blending stock, or as a source for specific aromatic compounds, namely benzene, toluene and xylene for use in petrochemicals production. The product stream of the reformer is generally referred to as a reformate. Reformate produced by this process has a high octane rating. Significant quantities of hydrogen are also produced as byproduct. Catalytic reforming is normally facilitated by a bifunctional catalyst that is capable of rearranging and breaking longchain hydrocarbons as well as removing hydrogen from naphthenes to produce aromatics. This process is different from steam reforming which is also a catalytic process that produces hydrogen as the main product. The book focuses on the use of catalysis in the Oil Refineries and in the Petrochemical Industries with particular reference to understanding the basic processes, development of appropriate catalysts and their characterization techniques.
