    Abstract: The process for producing a predetermined CXHYOZ product from a primary feedstock containing hydrocarbons and a secondary feedstock is disclosed, wherein X, Y and Z are integers. The process includes the steps of: providing primary feedstock; indirectly heating it generally in the absence of oxygen; cleaning the gas stream produced therefrom by removing CO2 and solids; determining the amount of CO and H2 therein; comparing the percentage of CO and H2 in the cleaned gas stream with the required CO and H2 to produce the predetermined CXHYOZ product; determining the additional of CO and H2 required; determining the secondary feedstock; calculating the amount of CO, H2 and heat produced from the secondary feedstock; partially oxidizing the secondary feedstock to produce heat and a secondary gas stream; combining the CO and H2 from both feedstocks to produce a mixed gas stream; adding a catalyst; and distilling to produce the predetermined CXHYOZ product.

    Abstract: A method and apparatus for cooling hot gas streams in the temperature range 800° C. to 1600° C. using multi-stage circulating fluid bed (CFB) coolers is disclosed. The invention relates to cooling the hot syngas from coal gasifiers in which the hot syngas entrains substances that foul, erode and corrode heat transfer surfaces upon contact in conventional coolers. The hot syngas is cooled by extracting and indirectly transferring heat to heat transfer surfaces with circulating inert solid particles in CFB syngas coolers. The CFB syngas coolers are staged to facilitate generation of steam at multiple conditions and hot boiler feed water that are necessary for power generation in an IGCC process. The multi-stage syngas cooler can include internally circulating fluid bed coolers, externally circulating fluid bed coolers and hybrid coolers that incorporate features of both internally and externally circulating fluid bed coolers.

    Abstract: 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.
