Abstract:
A method identifies the molecular structure of each component in a multicomponent mixture. The method includes (1) subjecting the multicomponent mixture to mass spectrometry to identify the formula of a molecule attributed to each obtained peak, and to identify abundance of the molecule; (2) subjecting the multicomponent mixture to collision induced dissociation; (3) performing mass spectrometry on each fragment ion generated via the collision induced dissociation in (2) to identify the core structure forming each fragment ion and abundance thereof; (4) dividing the molecules attributed to each peak in (1) into “classes” based on “a type and number of heteroatoms, and a DBE value”, and on all the molecules belonging to each “class”, estimating the existence state and abundance thereof; and (5) determining the core structure forming each molecule, for which the existence state is estimated in (4), and determining and assigning a side chain and a cross-link thereto.

In the hydrocarbon-producing apparatus, a vapor-liquid separation tank of a second vapor-liquid separation unit is provided with a filling material layer. A vapor-liquid separation tank of the first vapor-liquid separation unit has a first return line. The vapor-liquid separation tank of the second vapor-liquid separation unit has a second return line. A light component of light oil discharged from a bottom of the vapor-liquid separation tank is returned to a portion between a top side above a return-location from the second return line within the vapor-liquid separation tank of the second vapor-liquid separation unit, and a line directly connected with a cooler installed on the first vapor-liquid separation unit through the first return line. A heavy component of light oil discharged from a bottom of the vapor-liquid separation tank of the second vapor-liquid separation unit is returned to the filling material layer through the second return line.
