Abstract
A process and apparatus for the pyrolysis of coal or other hydrocarbon bearing materials in which the material is fed into the upper end of a rotating cylinder and is heated in a plurality of stages, the heated material passing from the cylinder into a char pit, and treating the resulting materials to separate them into fuels having different characteristics. One feature of the invention is the addition of CaO or NaHCO.sub.3 to the charged materials and addition of H.sub.2 O in the char pit to facilitate removal of sulfur. Another feature is the scraping and brushing of the inside surfaces of the rotary cylinder to clean the interior of the cylinder during the conduct of the process.
Claims7
Apparatus for the pyrolysis of hydrocarbon bearing materials comprising:
- a rotary kiln the axis of which is inclined with respect to the horizontal, means for introducing said material into an upper portion of said kiln, means for rotating said kiln about its axis to cause said material to move within said kiln from its point of introduction toward a lower portion of said kiln, means for heating said material through the walls of said kiln as said kiln rotates and as said material moves within the kiln to a temperature at which a portion of said material is volatile, the lower portion of said kiln having an opening therein through which material may pass out of said kiln, a stationary supporting structure within said kiln, a scraping shoe, and a lever pivotally attached to said structure, said lever being at its one end pivotally connected to said shoe and weighted at its other end, the weight of said weighted end urging said shoe against the wall of said kiln.
Apparatus for the pyrolysis of hydrocarbon bearing material comprising:
- a rotary kiln the axis of which is inclined with respect to the horizontal, means for introducing said material into an upper portion of said kiln, means for heating said material through the walls of said kiln as said kiln rotates and as said material moves within the kiln to a temperature at which a portion of said material is volatile, said lower portion of said kiln having an opening therein through which material may pass out of said kiln, means for withdrawing gas through said opening to produce a vacuum within said kiln, stationary supporting structure within said kiln, a scraping shoe, and means pivotally attached to said shoe and to said structure for yieldably urging said shoe outwardly against a wall of said kiln as said kiln rotates.
