The Process of Chemical Reactions
... Why, then, does it take place rapidly at 1200 °C? Similarly, why does the combustion of gasoline take place more quickly when the fuel air mixture in a cylinder of your car is compressed into a smaller volume by a moving piston? How does your car’s catalytic converter speed the conversion of NO( g) ...

Formic acid oxidation reaction on a PdxNiy bimetallic nanoparticle
... Among the Pd-based bimetallic catalysts, PdeNi catalysts have been prepared by various methods. The first is the chemical reduction reaction. For example, Scott et al. [11] reported the carbon nanofibers (CNFs) supported PdeNi nanoparticles that were prepared by a chemical reduction reaction using N ...

Cracking (chemistry)
In petroleum geology and chemistry, cracking is the process whereby complex organic molecules such as kerogens or heavy hydrocarbons are broken down into simpler molecules such as light hydrocarbons, by the breaking of carbon-carbon bonds in the precursors. The rate of cracking and the end products are strongly dependent on the temperature and presence of catalysts. Cracking is the breakdown of a large alkane into smaller, more useful alkanes and alkenes. Simply put, hydrocarbon cracking is the process of breaking a long-chain of hydrocarbons into short ones. More loosely, outside the field of petroleum chemistry, the term ""cracking"" is used to describe any type of splitting of molecules under the influence of heat, catalysts and solvents, such as in processes of destructive distillation or pyrolysis. Fluid catalytic cracking produces a high yield of petrol and LPG, while hydrocracking is a major source of jet fuel, Diesel fuel, naphtha, and again yields LPG.
