Molecular composition reforming

CATALYTIC REFORMING A process by which hydrocarbons in petroleum are heated, often in contact with a catalyst, in order to change their molecular composition. [Pg.856]

In the previous section, we built and solved the reformer model using bulk property and total PNA information only. This approach works reasonably when the actual feedstock is quite similar to the Default or selected feed type. In actual refinery operation, the feed type may change quickly or may not have been analyzed for feed type information. In this section, we discuss an approach to integrate measured molecular composition analysis with the feed type to improve modeling results. This method has shown significant improvement in model predictions, especially in the petrochemical reformers where accurate predictions of aromatic content are significant... [Pg.329]

A PAFC, operating on reformed natural gas (900 Ib/hr) and air, has a fuel and oxidant utilization of 86% and 70% respectively. With the fuel and oxidant composition and molecular weights listed below, (a) How much hydrogen will be consumed in lb mol/hr (b) How much oxygen is consumed in lb mol/hr (c) What is the required air flow rate in lb mol/hr and Ib/hr (d) How much water is generated (e) What is the composition of the effluent (spent) fuel and air streams in mol % ... [Pg.287]

Since most biomass compositions are hydrocarbons or oxidative hydrocarbon with a general molecular formula of CnlT,nOz [25], biomass processing can use similar technologies for the hydrogen production via natural gas. The reactions of steam reforming of biomass, biomass partial oxidation, and biomass autothermal reforming are summarized in Table 9.5 [25]. [Pg.353]
