A METHOD FOR PRODUCING METALLURGICAL COKE FROM NON-COKING COAL
The present disclosure relates to a method for producing metallurgical coke from non-coking coal. The method comprising, densifying, the non-coking coal to form pellets. The densified pellets will be placed in a microwave oven within plurality of bricks and are subjected for pyrolysis. For carrying our pyrolysis, the pellets are carried out by heating, the pellets in the microwave oven at a predetermined temperature under an inert atmosphere at atmospheric pressure, and then the pellets are cooled in the microwave oven under the inert atmosphere. This process coverts non-coking coal to the metallurgical coke in a quicker time, and without use of any susceptors.
TORREFIED BIOMASS BRIQUETTES AND RELATED METHODS
The presently disclosed subject matter relates to torrefied biomass briquettes and methods for producing the same that make use of a mixture of lightly torrefied material (LTM) and highly torrefied material (HTM) and/or make use of torrefied materials that are subjected to a hydrolysis pretreatment prior to being torrefied.
PROCESSING OF LOW RANK COAL
A method of processing coal includes placing coal having a heat content between about 3,000 BTU/lb and about 9,000 BTU/lb and a moisture content between about 20 wt % and about 60 wt % in a vessel. The coal is heated by conduction. A pressure in the vessel is reduced to below atmospheric pressure, thereby reducing the coal, such that an average primary particle size of the coal is less than 1 millimeter. The reduced coal is shaped to yield a fuel composition.

A method of preparing a fuel composition includes placing coal having a heat content between about 3,000 BTU/lb and about 9,000 BTU/lb and a moisture content between about 20 wt % and about 60 wt % in a vessel. The coal is exposed to heat and a pressure less than atmospheric pressure within the vessel, thereby reducing the coal, such that an average primary particle size of the coal is less than 1 millimeter. A binder is introduced to the vessel, such that the coal combines with the binder to yield a mixture. The mixture is shaped to yield a fuel composition.

Method and apparatus for treating organic matter
An apparatus includes a material feeder having an input and an output, a reducing nozzle attached to the output of the material feeder, an electrically conductive tube having a first end surrounding at least a portion of the reducing nozzle, and an induction coil surrounding all or part of the electrically conductive tube. A method for treating organic matter includes inductively heating the electrically conductive tube using the induction coil, and supplying the organic matter to the input of the material feeder. The organic matter is pushed through the reducing nozzle using the material feeder, such that the organic matter forms a continuous tube, semi-continuous tube or pellets of organic matter that is pushed through the electrically conductive tube. The continuous tube, semi-continuous tube or elongated pellets of organic matter is treated using the heat within the electrically conductive tube.
