thermal cracking

thermal cracking

[′thər·məl ′krak·iŋ]
(chemical engineering)
A petroleum refining process that decomposes, rearranges, or combines hydrocarbon molecules by the application of heat, without the aid of catalysts.

[2] postulated several thermal cracking reaction models that could be incorporated into numerical simulations of thermal recovery processes for the Athabasca oil sands.
This article, the second in a series of three pieces about the used oil industry, is a general discussion of the used oil thermal cracking process which converts used oil to distillate gasoil.
This technique minimizes the effect of thermal cracking on refractory lining performance.
The high viscosity binder can become embrittled at low temperatures and susceptible to fatigue and thermal cracking.
Hence, polymer modified asphalt stored at an excessively high temperature of 180 [degrees] C will be more susceptible to fatigue cracking and thermal cracking due to asphalt age hardening (high G*).
The phenomenon of thermal cracking is manifested as a result of a sharp decrease in temperature (low-temperature cracking) or because of the fatigue induced by repeated thermal cycles (thermal-fatigue cracking) [5].
A somewhat greater degree of thermal cracking occurs in this process which imparts significant instability to the product.
Resistant to thermal cracking - Thermal cracking, thermal fatigue and heat checking all describe the same mechanism of failure - cracks forming as a result of the thermal cycle and the strains that consequently develop.
