Pyrolysis is a thermochemical decomposition of organic material at elevated temperatures in the absence of oxygen. Pyrolysis typically occurs under pressure and at operating temperatures about 430 Â°C (800 Â°F). Pyrolysis is a special case of thermolysis, and is most commonly used for organic materials, being, therefore, one of the processes involved in charring. In general, pyrolysis of organic substances produces gas and liquid products and leaves a solid residue richer in carbon content. Extreme pyrolysis, which leaves mostly carbon as the residue, is called carbonization.
Vascular (Dialysis) Access Surgery. Hemodialysis is a treatment for kidney failure that uses a machine, outside the body, to remove waste products for the blood. In order for the treatment to work, large volumes of blood must be rapidly removed from the patientâs body, passed through filters in the machine, and returned to the body.
