Low temperature pyrolysis method of caking middling coal

The present disclosure relates to the technical field of pyrolysis and improvement of caking middling coals, in particular to a low temperature pyrolysis method of a caking middling coal. The present disclosure provides a low temperature pyrolysis method of a caking middling coal, including the following steps: conveying the caking middling coal into a pyrolysis reactor through a top of the pyrolysis reactor; dividing a reaction chamber of the pyrolysis reactor into a drying section, a softening section, a melting and depolymerization section, a solidification section, and a cooling section by means of multi-channel gas distribution; and conducting zoned temperature control-based pyrolysis to obtain semi-coke at a bottom of the reactor as well as tar and coal gas at the top of the reactor. The pyrolysis method can well avoid caking and swelling of the caking middling coal during pyrolysis.

Process for devolatizing a feedstock

Provided herein is a method for devolatizing a solid feedstock. The solid feedstock is treated to a produce a particle size laying between 1 cm.sup.3 and 100 cm.sup.3. The solid feedstock is passed into a device connected to an outlet of a compaction screw auger comprising an assembly including a solid feedstock injector, a retort, a side arm for injecting a heated gas comprising hydrogen, and a process auger. The solid feedstock is contacted with the heated gas at a temperature of 500 C. to 1000 C. for a time of 60 seconds to 120 seconds, whereby the solid feedstock is converted into a gas stream and a solid stream.

CONTINUOUS PROCESS PYROLYSIS SYSTEM

The invention provides apparatus and method of pyrolysing feedstock to produce char. A feedstock advancing mechanism in a lower portion of a substantially sealed reaction chamber advances the feedstock laterally along the lower portion as it pyrolyses in its progression from the proximal end to the distal end. Char is discharged from the distal end of the reaction chamber. A control system controls at least the flow rate of oxygen containing gas entering the chamber via the inlet port in response to the temperature measurements in the reaction chamber so that the temperature measurements are appropriate for the production of char from the feedstock and so that a zone of volatile gas combustion is established in the headspace, involving essentially complete consumption of all incoming free oxygen in the headspace without contacting the feedstock.
