    摘要: A multi-stage process for the production of hydrocarbon products from syngas, each stage of the process comprising one or more syngas conversion reactors in which syngas is partially converted into hydrocarbon products at conversion conditions, each conversion reactor having a syngas entry stream system which system combines two or more entry streams of syngas and which system delivers the combined syngas to the syngas conversion reactor, the syngas entry system combining at least one entry stream of syngas being a syngas stream obtained in a partial oxidation process (for the first stage) or an exit stream of syngas from the previous stage, together with a reformed syngas (for all stages except the first stage), with another syngas stream being a recycle stream from the conversion reactor and a syngas exit stream system which discharges an exit stream of syngas from the reactor, the exit stream partly being used as the recycle stream to the syngas entry system as mentioned above, and, in the case that there is a further stage in the process, as feed for the next stage.

    摘要: CNT materials comprising aligned carbon nanotubes (CNTs) with pre-determined site densities, catalyst substrate materials for obtaining them and methods for forming aligned CNTs with controllable densities on such catalyst substrate materials are described. The fabrication of films comprising site-density controlled vertically aligned CNT arrays of the invention with variable field emission characteristics, whereby the field emission properties of the films are controlled by independently varying the length of CNTs in the aligned array within the film or by independently varying inter-tubule spacing of the CNTs within the array (site density) are disclosed. The fabrication of microelectrode arrays (MEAs) formed utilizing the carbon nanotube material of the invention is also described.
