Activation by Charcoal

Steady State Simulation of a Rotary Kiln for Charcoal Activation

−− This work presents a mathematical modeling and steady state simulation study of the pilot scale rotary kiln behavior, which was designed to activate charcoal obtained from the raw materials of region of Cuyo-Argentina. The proposed model aims for acquiring useful information to select operating conditions and design parameters. It is a simplified mathematical model that consists of a system ...

Melanosis ilei induced by prolonged charcoal ingestion

Gastrointestinal melanosis is observed most frequently in the colon it also can develop in the ileum, duodenum and esophagus very rarely. Melanosis ilei was thought that causative materials such as aluminum, magnesium, silicate, titanium and other compounds entered the body through the ingestion of agents. We experienced a case of melanosis in the terminal ileum that a 65-year-old female patien...

Camphor intoxication treated by charcoal haemoperfusion.

Introduction Camphor is used as a proprietary preparation, most often as a 20% solution in arachis oil, and is applied to the skin for the supposed relief of muscle pain and symptoms of the common cold. Intoxication is usually accidental and, although reports are rare, Silbert (1973) drew attention to the risk of camphor poisoning in children. Symptoms following ingestion include tremors, hallu...

Charcoal-induced pseudomelanosis ilei.

outpatient department because of anal bleeding. She had been diagnosedwith ulcerative proctitis about 1 year previously and had experienced intermittent anal bleeding during treatment at a local clinic. She had no significant medication history and in particular had not used laxatives or oral iron. The initial colonoscopy revealed numerous variable-sized areas of black pigmentation in the mucos...
