摘要： A solids circulation system receives a gas stream containing char or other reacting solids from a first reactor. The solids circulation system includes a cyclone configured to receive the gas stream from the first reactor, a dipleg from the cyclone to a second reactor, and a riser from the second reactor which merges with the gas stream received by the cyclone. The second reactor has a dense fluid bed and converts the received materials to gaseous products. A conveying fluid transports a portion of the bed media from the second reactor through the riser to mix with the gas stream prior to cyclone entry. The bed media helps manipulate the solids that is received by the cyclone to facilitate flow of solids down the dipleg into the second reactor. The second reactor provides additional residence time, mixing and gas-solid contact for efficient conversion of char or reacting solids.

摘要： A hybrid plant and method for producing liquid fuel product from hydrogen and carbon monoxide containing streams produced by gasifying solid carbonaceous feedstock and steam reforming of light fossil fuels. When a gasification unit in the hybrid plant is operating at reduced capacity or is not operational, oxygen that would have been used in the gasification unit is diverted to a light fossil fuel conversion unit containing an autothermal reformer to increase H2-rich syngas flow to a liquid fuel production unit and maintain liquid fuel production at near nameplate capacity.

摘要： The invention relates to an autothermic method for the continuous gasification of substances (14) rich in carbon in a vertical processing chamber (100) having a calcination zone (C) and an oxidation zone (D), in which the calcinated substances rich in carbon oxidize with gas containing oxygen, wherein the gaseous reaction products are withdrawn at the top (G) of the vertical processing chamber (100). The vertical processing chamber is configured in the shape of a vertical shaft furnace (100), which is continuously flowed through from the top to the bottom by a bulk product (13) conducted in a cycle, which itself is not oxidized, wherein the substances (14) rich in carbon are added to the bulk product (13) before entering (3) the furnace, and the gas containing the oxygen is introduced in and/or beneath the oxidation zone (D), whereby the rising gas flow is facilitated. An after-cooling zone (F), in which the bulk product is cooled to below 100° C., is configured by introducing at least part of the gas containing the oxygen at the lower end (4) of the vertical processing chamber (100).

摘要： This invention relates to gasification of high ash bituminous coals that have high ash fusion temperatures. The ash content can be in 15 to 45 weight percent range and ash fusion temperatures can be in 1150° C. to 1500° C. range as well as in excess of 1500° C. In a preferred embodiment, such coals are dealt with a two stage gasification process—a relatively low temperature primary gasification step in a circulating fluidized bed transport gasifier followed by a high temperature partial oxidation step of residual char carbon and small quantities of tar. The system to process such coals further includes an internally circulating fluidized bed to effectively cool the high temperature syngas with the aid of an inert media and without the syngas contacting the heat transfer surfaces. A cyclone downstream of the syngas cooler, operating at relatively low temperatures, effectively reduces loading to a dust filtration unit. Nearly dust- and tar-free syngas for chemicals production or power generation and with over 90%, and preferably over about 98%, overall carbon conversion can be achieved with the preferred process, apparatus and methods outlined in this invention.
