This chapter is divided in two parts additives for motor fuels and additives for lubricants. Concerning additives for gasoline, one will find here in Chapter 9 some useful complements to Chapter 5, especially regarding the synthesis of additives and their modes of action. 

Mixtures of CO—H2 produced from hydrocarbons, as shown in the first two of these reactions, ate called synthesis gas. Synthesis gas is a commercial intermediate from which a wide variety of chemicals are produced. A principal, and frequendy the only source of hydrogen used in refineries is a by-product of the catalytic reforming process for making octane-contributing components for gasoline (see Gasoline and OTHER MOTOR fuels), eg. 

A further fact must be taken into account, which for obvious reasons did not appear in Haslam s article. As a consequence of our contracts with the Americans, we received from them above and beyond the agreement many very valuable contributions for the synthesis and improvement of motor fuels and lubrication oils, which just now during the war are most useful to us. It need not be especially mentioned that without lead-tetraethyl the present method of warfare would be unthinkable. The fact that since the beginning of the war we could produce lead-tetraethyl is entirely due to the circumstances that, shortly before, the Americans had presented us with the production plans, complete with experimental knowledge. Thus the difficult work of development (one need only recall the poisonous property of lead-tetraethyl, which caused many deaths in the U.S.A.) was spared us, since we could take up the manufacture of this product together with ail the experience that the Americans had gathered over long years.

Despite the current decrease of oil prices, the conversion of syngas to alcohols remains an attractive objective. Many companies are involved in alcohols synthesis projects, based on high pressure or low pressure technologies, with motor-fuels and octane boosters as targets. The I.F.P. (France Idemitsu (Japan) R D program is focused on the co-produc-tion of methanol and light alcohols. These product... 

Benzene, a component of motor fuel that is also widely used as an industrial solvent and as a starting material in organic synthesis, is a hematopoietic toxin. Chronic exposure to benzene vapors leads to pancytopenia, that is, decreased production of all types of blood cells (erythrocytes, leukocytes, and platelets). The long-term effect of benzene exposure is acute leukemia. 

In considering the chemical reactions based on the light olefins it is obvious that natural gas liquids are at a disadvantage in comparison with the corresponding refinery cuts. These contain varying but substantial percentages of olefins as such—the results of thermal and catalytic decomposition of the heavier petroleum molecules. But refinery olefins are also in demand for synthesis to premium motor fuels. It is fortunate that there are abundant supplies of natural gas paraffins for conversion to provide adequate raw material for our olefin chemistry. 

The major uses of mixed xylene are in aviation gasoline and protective coatings, and as a solvent for alkyd resins, lacquers, enamels and rubber cements. wetrr-Xylene is used as a solvent, as an intermediate for dyes and organic synthesis, especially isophthalic acid and insecticides, and in aviation fuel or// o-xylene is used in manufacture of phthalic anhydride, vitamin and pharmaceutical synthesis, dyes, insecticides, motor fuels para-xylene is used in synthesis of terephthalic acid for polyester resins and fibres, vitamin and pharmaceutical syntheses, and insecticides (Lewis, 1993).

In Germany, before and during the Second World War, a large amount of ethylene was produced from acetylene derived from coke oven gas. Coke ovens also provided essentially all the aromatics in Germany. Coal was also gasified, giving synthesis gas, a mixture of CO and H2. Products such as ammonia and methanol were catalytically produced from this synthesis gas. Fischer-Tropsch technology was also developed to convert synthesis gas to motor fuels. 

Meanwhile, Saso) II went on stream (1980) using the entrained-bed process with a capacity of approximately 2 million t/a and Sasol III with the same capacity is under construction and its production startHip is scheduled for 1982. By then, roughly 40% of the motor fuels consumed in South Africa will be produced by Fischer-Tropsch synthesis [2,12]. 

Methanol is used as a starting material for the synthesis of acetic acid and for many types of adhesives, fibers, and plastics. It is also used (and such use may increase) as a motor fuel. Methanol is highly toxic to humans and can lead to blindness and death if ingested. 

Another potentially adverse impact on fermentation ethanol markets is presented by the options available for the manufacture of mixed alcohols from synthesis gas. Sufficient experimental data have been accumulated to show how the alcohol yields and distributions can be manipulated and what catalysts and conditions are effective. Some of these data have established the utility of mixed alcohols as motor fuels and motor fuel components.
