Process and Apparatus for Steam-Methane Reforming

Номер: US20120058028A1

Methane reacts with steam generating carbon monoxide and hydrogen in a first catalytic reactor; the resulting gas mixture undergoes Fischer-Tropsch synthesis in a second catalytic reactor. In the steam/methane reforming, the gas mixture passes through a narrow channel having mean and exit temperatures both in the range of 750° C. to 900° C., residence time less than 0.5 second, and the channel containing a catalyst, so that only reactions having comparatively rapid kinetics will occur. Heat is provided by combustion of methane in adjacent channels. The ratio of steam to methane may be about 1.5. Almost all methane will undergo the reforming reaction, almost entirely forming carbon monoxide. After Fischer-Tropsch synthesis, the remaining hydrogen may be fed back to the combustion channels. The steam for the reforming step may be generated from water generated by the chemical reactions, by condensing products from Fischer-Tropsch synthesis and by condensing water vapor generated in combustion.

Deep desulfurization of hydrocarbon feeds containing undesired organosulfur compounds to produce a hydrocarbon product having low levels of sulfur, i.e., 15 ppmw or less of sulfur, is achieved by first subjecting the entire feed to an extraction zone to separate an aromatic-rich fraction containing a substantial amount of the aromatic refractory and sterically hindered sulfur-containing compounds and an aromatic-lean fraction containing a substantial amount of the labile sulfur-containing compounds. The aromatic-rich fraction is contacted with isomerization catalyst, and the isomerized aromatic-rich fraction and the aromatic-lean fraction are combined and contacted with a hydrotreating catalyst in a hydrodesulfurization reaction zone operating under mild conditions to reduce the quantity of organosulfur compounds to an ultra-low level.
