| 20090217576 | Method and Device for the Coking of High Volatility Coal - The invention relates to a method for the coking of coal, in particular coal with a high or alternating volatility, in coking plants comprising coking chambers, according to the non-recovery method or the heat-recovery method. The invention also relates to a device, which can be used to carry out said method simply, as the overheating of the coking furnace is prevented by the injection of water vapour. If a battery of coking furnaces is used, the disclosed method can be carried out irrespective of the number of said furnaces. | 09-03-2009 |

| 20100293847 | Engine fuels from coal volatile matter - Apparatus and a process are described for compressing superheated steam into porous coal chunks in a chamber, and, after a time interval, expanding this steam out of the chamber, and repeating this steam cycle of compression followed by expansion. Thusly heated by the steam, volatile matter separates from the solid coke portion of the coal and separate volatile matter and coke products can be produced from coal or biomass fuels. These volatile matter liquids and tars can be used as fuel components in slurry fuels, for internal combustion engines used in our surface transportation industries. These solid coke products can be used as boiler fuel in steam electric plants. In this way our large domestic reserves of coal can be used as a fuel source, not only for electric power generation, but also for our surface transportation needs. | 11-25-2010 |

| 20110119998 | CO Generator and Process for Desulfurizing Solid Carbon-based Fuels - A process is presented whereby hot Carbon Monoxide (CO) gas is generated under pressure in an external Combustor by the partial oxidation of a carbon-based solid fuel. This pressurized, hot CO gas or CO gas mixture is then transferred to a desulfurizing vessel containing a second carbon-based solid fuel. The hot CO laden gas and solid material contact in a counter-flow arrangement where the CO reacts with and removes sulfur impurities from the second carbon fuel. The temperature of the pressurized CO laden gas from the Combustor is controlled by varying the oxidizer feed gas composition. The Combustor also contains a means for desulfurizing its feed fuel by flowing a portion of the hot CO gas generated up through the inlet solid fuel feed line. The desulfurizer vessel is comprised of three stages, a preheat stage, a desulfurizing stage, and a cooling stage. Hot CO gas from the Combustor enters the desulfurizer section where it mixes with a recycle gas stream coming up from the cooling stage below. The gas exiting the desulfurizer section is split into an exhaust stream and a recycle stream. The recycle stream travels up through the preheat section and heats the incoming material being treated. The cooled recycle gas exits the top of the system and flows to a recycle blower. The recycle gas is scrubbed of impurities by activated carbon prior to being re-injected into the bottom of the cooling section. The hot exhaust stream from the desulfurizer section is first quenched by mixing with a small water spray and a second exhaust gas recycle stream. The cooled exhaust gases are passed over a catalyst that converts carbonyl sulfide (COS) and carbon disulfide (CS2) gases to hydrogen sulfide (H2S), which are then removed from the system by conventional processes. The Combustor/Desulfurizer process is useful or producing high-value low-sulfur petroleum coke by generating the required heat from a low-value coke, such as fluid coke. In an alternate embodiment, the combustor is used to calcine and desulfurize coal or other solid carbon fuel in a batch process. The Combustor can also be used independently to supply hot reducing gas for any application. | 05-26-2011 |
