THERMAL CRACKING AND CORRESPONDING PERMEABILITY OF …
THERMAL CRACKING AND CORRESPONDING PERMEABILITY OF …

In this work, thermal ,cracking, inside an ,oil, shale sample under different tem-peratures was tested using a micro-CT system. The critical ,temperature, was determined at which sharp thermal ,cracking, in the ,oil, shale sample occurs. It was found that the critical ,temperature, of Chinese Fushun ,oil, shale is 350 °C.

Difference Between Thermal Cracking and Catalytic Cracking ...
Difference Between Thermal Cracking and Catalytic Cracking ...

27/9/2017, · Temperature. Thermal Cracking: The temperature used in thermal cracking ranges between 500-700 o C. Catalytic Cracking: The temperature used in catalytic cracking ranges between 475-530 o C. Pressure. Thermal Cracking: The pressure used in thermal cracking is about 70 atm. Catalytic Cracking: The pressure used in catalytic cracking is about 20 atm. Applications

The Lowdown on Oil Breakdown - Machinery Lubrication

When this occurs, the layer of oil that comes in contact with the hot machine surface or compressed air bubble can chemically change. Temperatures in excess of 200°C (400°F) are typically required to initiate a thermal failure event.

Typical modern catalytic cracking reactors operate at 480–550 °C (900–1,020 °F) and at relatively low pressures of 0.7 to 1.4 bars (70 to 140 KPa), or 10 to 20 psi. At first natural silica-alumina clays were used as catalysts, but by the mid-1970s zeolitic and molecular sieve-based catalysts became common.
