| 208407000 | Specified agitation or circulation in gas contact zone | 9 |
| 20100025305 | Apparatus for Separating Solids from Gas - An apparatus separates solids from gas in a vessel using cyclones. The cyclones have centers located at different distances from a center of the vessel, but the inlets to the cyclones are located at the same distance from the center to balance the proportions of catalyst fines entering each cyclone. | 02-04-2010 |
| 20100051512 | APPARATUS AND METHOD FOR DRY DISTILLATION OF OIL SHALE - An apparatus for dry distillation of oil shale, has a vibration bed with multiple layers, a gas retort, a feeding system, a feeding hole, a screen plate, a water seal tank, a discharging system, and a gas outlet. The feeding system and the feeding hole are disposed at the top of the gas retort. The screen plate is disposed on the vibration bed. The layers of the vibration bed are obliquely disposed in the gas retort. The number of layers of the vibration bed is nine. Three hot recycle gas inlets are disposed on the wall of the gas retort and respectively below the fourth layer, the fifth layer and the sixth layer of the vibration bed. A cold recycle gas inlet is disposed below the ninth layer of the vibration bed. The water seal tank and the discharging system are disposed at the bottom of the gas retort. The gas outlet is disposed at the top of the gas retort. The apparatus features a simple structure, convenient operation, low cost, and a high oil recovery and resource unitization rate. | 03-04-2010 |

| 20130146507 | METHOD FOR THE PYROLYTIC EXTRACTION OF HYDROCARBON FROM OIL SHALE - A method for the pyrolytic extraction of hydrocarbons such as shale oil from kerogen. Oil shale containing kerogen which has been ground into particulate form, is cascaded downwardly between a plurality of rotating trays within a heated processing chamber. As the hydrocarbons are volatized within the chamber, the volatiles are collected and condensed within a condenser or other suitable recovery apparatus. | 06-13-2013 |
| 20140251875 | Process and System for Processing Tar Sand - A process and system to separate crude from tar sands. A tar sand and crude oil mixture is created using ground tar sands. The tar sand and crude oil mixture is mixed under high pressure in a treatment vessel with either natural gas or exhaust gas from an internal combustion engine. The mixture is then moved through a entrainment vessel still under the high pressure. When the mixture is removed from the entrainment vessel excess gas is removed from the mixture. The crude oil is then separated from the sand typically through a cyclone separator. A portion of the crude oil may be used to mix with the ground tar sand on the front end of the process. | 09-11-2014 |

| 20090095659 | Petroleum products from oil shale - A system for producing petroleum products from oil shale includes one or plural kiln lines made up of plural series-connected, indirect-fired, inclined rotary kilns. Plural kiln lines are operated for parallel processing. Oil shale is advanced through kilns in succession and exhausted from each kiln line substantially free of hydrocarbons. Successive kilns along the advancement of oil shale are maintained at successively higher temperatures. A fuel distinct from hydrocarbons in oil shale, such as syngas from a gasifier or hydrogen gas from a separator, drives pyrolysis to extract hydrocarbons. A refining unit located proximate to the kiln lines upgrades extracted hydrocarbons into petroleum products and separates the petroleum products by criteria. A heat extraction unit recovers heat from exhausted oil shale for reuse in kilns. A method involves drying oil shale followed by heating dry oil shale in successively hotter pyrolysis environments. | 04-16-2009 |

| 20090200211 | Process for improved liquefaction of fuel solids - The invention provides a liquefaction process using comminuted fuel solids from a steam-driven shear field, with controlled water content and optionally coated with a catalyst. The method allows fuel solids to be liquefied efficiently during comminution or when they are supplied in the form of a slurry or as free-standing solids. | 08-13-2009 |
| 20110068050 | Process for distillation and decarbonization of oil shale species using fluidized bed - The present invention discloses a process for dry distillation and decarbonization of oil shale species using fluidized bed. The shale oil contained in oil shale having certain size distribution in fluidizing condition is gasified by using high temperature dry gas and/or high temperature stream as heat carrier and fluidizing medium, meanwhile, dry gas dissolves some organics in oil shale, that is, fluidizing, dry distillating and deoiling. The powder which has removed shale oil is fluidized by high temperature air under oxygen-rich condition. The carbon in oil shale is combusted, i.e. fluidizing decarbonization. | 03-24-2011 |

| 20100288678 | HOT SOLIDS PROCESS HAVING AN OUTPUT SUITABLE FOR THE INPUT TO A PETROCHEMICAL PROCESS - A hot solids process wherein a predetermined output, which is designed to be suitable for use as an input to a petrochemical process, is capable of being generated through the use of the hot solids process. The mode of operation of such a hot solids process is designed to be such that preferably a portion of the otherwise normally unusable product output, which is produced from a petrochemical process, is designed to be utilized as an input to the hot solids process for purposes of generating from the hot solids process the predetermined output that is suitable for use as an input to a petrochemical process. | 11-18-2010 |
