n-Butane and isobutane are used in a test engine to examine the importance of molecular structure in determining knock tendency. The experimental results are interpreted using a detailed chemical kinetic model. Temporally resolved samples were withdrawn from the combustion chamber, providing measured ...
Unlike catalysts reported previously, hBN limits the amount of undesired CO x and instead forms C 2 and C 3 olefins as the main side products. Kinetic experiments suggest a mechanism in which the rates of n -butane and isobutane consumption are dependent on O 2 adsorption. Kinetic and ...

The entropies ofn‐butane (S298°= 75.8 e.u.) and isobutane (S298°= 70.0 e.u.) have been calculated from thermal data by the third law of thermodynamics. In this connection, heat capacity data for isobutane over the temperature range 79°—261°K have been obtained by the Nernst meth...
An n-butane/isobutane splitter is operated by compressing the isobutane overhead to increase its condensing temperature, using the compressed overhead to heat bottoms in a reboiler, which is operated to condense the overhead and cooling the condensed overhead to a temperature no lower than the te...

The reactions of CF3 radicals with propane, n-butane and isobutane have been studied using trifluoromethyl iodide as the source of free radicals. The overall Arrhenius parameters are: [graphic omitted] Analysis of the alkyl iodides in the products of each system allows calculation of the Arrhenius...
The primary adsorber removes impurities such as C2, C3, n-butane and 1-butene, the secondary adsorber removes isobutene, and the C2, C3 hydrocarbon impurities are further removed in the tertiary adsorber, and the purity of the product is greater than 99.99%. (3) By natural gas ...
