| 20090188468 | Modified common rail fuel injection system - A modified common rail fuel injection system, for diesel engines, is described, for use with slurry fuels comprising dissolved supplementary atomizing gases. Two separate high pressure fluid circuits are utilized to supply and operate the engine fuel injectors. A high pressure fuel circuit comprises, a high pressure pump delivering engine fuel into a fuel common rail, from which the fuel is delivered into each fuel injector, and from there into each engine combustion chamber. A high pressure hydraulic circuit comprises, a high pressure pump delivering hydraulic fluid into a hydraulic common rail, from which the hydraulic fluid acts on drivers of the injector valves, via timed on-off valves, to operate each fuel injector at the proper time in each engine cylinder cycle. Reliable operation of the fuel injectors is not impaired by slurry fuel degassing or slurry fuel particles. | 07-30-2009 |
| 20100147233 | Coke burning engine - A coke burning engine is described wherein hot coke fuel chunks are first compressed with air and reacted therewith to form a carbon monoxide rich gas, during a compression cycle time period. Next these primary reacted gases are mixed into and burned with secondary air during a blowdown cycle time period. These fully reacted gases are expanded though an expander engine whose power output drives the air compressor, and yields a net useful engine power output. | 06-17-2010 |

| 20100293837 | Engine fuels from coal and biomass 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 |

| 20110041394 | Rotary tar slurrifier - A method for reducing tar fuel viscosity by steam heating, during slurrification in a rotary slurrifier, is described for creating slurries of many small tar particles suspended in a continuous water phase. This heating is done at pressure to avoid evaporation of the water. The tar in water slurry is evaporatively cooled by subsequent depressurization. | 02-24-2011 |
| 20110108404 | Cyclic batch coal devolatilization apparatus - Apparatus and a process are described for compressing superheated steam into porous coal batches in chambers, and, after a time interval, expanding this steam out of the chambers, 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.
