Electrical resistivity (also called specific electrical resistance or volume resistivity) is a fundamental property of a material that measures how strongly it resists electric current.Its inverse, called electrical conductivity, quantifies how well a material conducts electricity. A low resistivity indicates a material that readily allows electric current.

There are several ways to measure thermal conductivity; each is suitable for a limited range of materials. Broadly speaking, there are two categories of measurement techniques: steady-state and transient.Steady-state techniques infer the thermal conductivity from measurements on the state of a material once a steady-state temperature profile has been reached, whereas transient techniques ...

01-01-1986· (Keywords: coal; rheological properties; coal paste) The design of coal hydroliquefaction plants is strongly dependent on the hydrodynamic properties of the coal paste. These properties have to be known over a large range of temperatures, as the coal paste is supplied from the pumping site at ambient temperature and is pro- gressively heated to % 723 K.
H-Coal ® service utilizes a commercially proven ebullated-bed reactor for direct conversion of coal to high quality distillate fuels. Coal is crushed and pulverized to finely sized particles, and mixed with recycle oil to make a slurry that can easily pass up and out of the reactor with the liquid and gaseous products, while the much larger catalyst particles remain in the ebullated-bed reactor.
15-02-2018· If stainless steel is naturally anti-corrosive, why does it have to be passivated after welding? Passivation is done to restore the protective chromium-oxide layer on the steel surface after it has been destroyed through fabrication. Learn more here.

Stainless steel derives its corrosion-resistant properties from the chromium content. Chromium, when exposed to oxygen (air), forms a thin film of chromium oxide that covers the stainless steel surface and protects the underlying iron from rusting. The purpose of passivation is to augment and optimize formation of the chromium oxide layer.
