Page 30 - ... and normal heptane, used as a primary standard for measurement of knock characteristics. Thus, by definition, normal heptane has an octane number of zero and tiooctane of 1 00.

Page 30 - ... normal heptane just match its anti-knock quality. For example, if a gasoline is matched by a mixture of 75 parts octane and 25 parts heptane, its octane number is 75. In other words, octane number is defined by and is numerically equal to the percentage by volume of iso-octane (2,2,4-trimethylpentane) in a mixture of iso-octane and normal heptane, used as a primary standard for measurement of knock characteristics. Thus, by definition, normal heptane has an octane number of zero and iso-octane...
Page 31 - ... when the pressure of the oxygen in contact with the latter is reduced, oxygen is liberated (see Chemical equilibrium). When, without any change in temperature, an extra substance increases the speed of a chemical change, seemingly by its mere presence, without itself suffering any permanent change, we call this catalytic (Greek, Kara, down, Xixns, the act of loosing) or contact action.
Page 18 - A given quantity of liquid will dissolve at constant temperature quantities (by weight) of the gas which are proportional to the pressure of the...
Page 22 - ... The displacement of the water can proceed only to the point where equilibrium is reached between the surface and interfacial forces that resist the displacement and the forces that favor it. Thus, conditions of occurrence of the fluids within the oil-and-gas-bearing zones of reservoirs are probably such that : 1. The reservoir rock is completely wet by connate water and does not contact either oil or gas directly.
Page 22 - Fio. 6. — RELATION BETWEEN PERMEABILITY OF CORES AND CONNATE-WATER SATURATION. oil-and-gas-bearing strata not occupied by connate water must be filled with oil or gas. It has been observed that the water saturation is an inverse function of permeability. The oil or gas saturation must, therefore, be some direct function of permeability.
