โœฆ Synopsis

Continuous feeding of coal in a compressing screw extruder is described as a method of introducing coal into pressurized systems. The method utilizes the property of many bituminous coals of softening at temperatures from 350 to 400ยฐC. Coal is then fed much in the manner of common thermoplastics, using screw extruders. Preliminary results show that coals can be extruded at rates of about 3.3.kg/MJ, similar to those for plastics.

contents of the charcoals produced from the soft woods are > 70 wt % and of the same order as that of the Rhyzophorae. Similarly, the calorilic values of all charcoals do not differ significantly. Thus it may be concluded that these woods can be used instead of the Rhyzophorae to produce industrial
