    摘要： A process for heteroatom removal-enhancing hydrogenation of highly refractory aromatic ring structures that involves contacting a highly refractory structure having at least one aryl linkage connecting a first heteroaryl moiety and a moiety selected from the group consisting of an aryl moiety and a second heteroaryl moiety with supercritical water having a temperature of from about 400.degree. C. to about 600.degree. C. in the presence of from about 3.4 MPa to about 18.6 MPa of CO to produce lower molecular weight products having decreased aromatic and heteroatom content. The process has utility for producing more valuable lower molecular weight products having a reduced aromatic heteroatom content from starting materials that are highly refractory and widely considered to be difficult to upgrade such as coals and asphaltenes, and model compounds containing the biaryl linkages.

    摘要： A method of predicting the composition of hydrocarbon products of a complex carbonaceous material when exposed to specific time and temperature conditions is disclosed. In one embodiment, the material is characterized to obtain elemental, chemical and structural parameters. A representative chemical structure of the material is constructed based on the characterization information. The representative chemical structure is then stochastically expanded to a molecular ensemble chemical structural model that includes heteroatoms. The chemical structural model is coupled to a compositional yield model and the composition of the material products is determined using kinetic modeling. Methods are provided of constructing a chemical structural model of complex carbonaceous material, of coupling a molecular ensemble of chemical structures to a thermal chemical mechanism, of updating an ensemble of chemical structures during the kinetic modeling to reflect chemical reaction products and of eliminating molecules from the system.

    摘要： The present invention provides for a method of decreasing the metals content of metal containing petroleum streams by forming a mixture of the petroleum fraction containing those metals and an essentially aqueous electrolysis medium, and passing an electric current through the mixture at a voltage, pH and time sufficient to remove the metals such as Ni, V and Fe from the stream (i.e. to produce a petroleum fraction having decreased content of the metals). The cathodic voltage is from 0 V to -3.0 V vs. SCE at a pH of from 6 to 14, preferably 7 to 14, most preferably above 7 to 14.The invention provides a method for enhancing the value of petroleum feeds that traditionally have limited use in refineries due to their Ni and V content.
