REGULATORY CONTROL OF A PILOT ROTARY KILN

2006-1-1  INTRODUCTION The rotary kiln is the main process equipment in the activated carbon production by means of physical activation of charcoal with water vapor. In the last time, a complete study about the operation of a pilot rotary kiln for such process has been performed in our laboratory (Ortiz et al., 2003a, b; Ortiz et al., 2005).

2012-9-27  Rotary kilns are used by almost all important AC world manufacturers (i.e. Norit & Co.). Although Boateng and Barr published in 1996 a general thermal model for a rotary kiln that included heat transfer within the bed, studies about the modeling of the activation process of charcoal with water vapor in rotary kilns are lacking in the open

OPTIMAL OPERATION PROFIT OF A PILOT ROTARY KILN

2012-9-27  The direct-heated rotary kiln is broadly used for physi-cal activation. The pilot rotary kiln is a cylinder that rotates around its longitudinal axis and essentially oper-ates as a heat exchanger (Ortiz et al., 2003a). It has a diameter of 0.30 m with 3.70 m length and is covered with 0.15 m of insulation material. The cylinder is

The maceral composition followed the recent ICCP classification of huminite ( Sýkorová et al., 2005 ). The following main operation was required by the pilot scale experiments: low-temperature carbonization (I) and charcoal physical activation (II). The first operation (I) consists of charcoal manufacture in a pilot scale rotary kiln.

Thermal Regeneration of Activated Carbon

The pilot plant was designed to be operated in upflow or downflow condition. A picture of the assembled pilot-plant ready for operation is shown in Figure 4. The assembled pilot-plants were operated in the laboratory at various flow rates, and activated carbon loadings, to determine hydrualic charac- teristics.
