Abstract
The prediction of catalytic naphtha reforming products is one of the main challenges issues in oil sector. Investigating continues catalytic reforming (CCR) C5+, C1, C2, C3, and C4 are achieved by using response surface methodology (RSM). The process can be described in terms of several controllable variables which are research octane number (RON), naphthenes and aromatics. In present work, a quadratic polynomial equation for Naphtha C5+, SCFB H2 has been obtained by utilizing RSM and the results were tested by design of experiment (DOE) and ANOVA analysis. The experimental results show good agreement with the predicted model with a yield of C5+ ranging from 77.27 to 109 when the RON is in the range of 68 to 95, naphthenes (vol %) is in the range of 15 to 25 and aromatics (vol %) is in the range of 10 to 30. H2 yield varying from 0 to 1.37 is significantly affected by increasing C5+ and reduced by decreasing RON. The yield of other products is calculated by multiple regression analysis depending on C5+ conversion range 77–100. The yields of other products of reformer (C1, C2, C3, C4) can be calculated from correlation that developed using multiple regression analysis. This case study indicates that the statistical model is useful of CCR.
期刊介绍:
Petroleum Chemistry (Neftekhimiya), founded in 1961, offers original papers on and reviews of theoretical and experimental studies concerned with current problems of petroleum chemistry and processing such as chemical composition of crude oils and natural gas liquids; petroleum refining (cracking, hydrocracking, and catalytic reforming); catalysts for petrochemical processes (hydrogenation, isomerization, oxidation, hydroformylation, etc.); activation and catalytic transformation of hydrocarbons and other components of petroleum, natural gas, and other complex organic mixtures; new petrochemicals including lubricants and additives; environmental problems; and information on scientific meetings relevant to these areas.
Petroleum Chemistry publishes articles on these topics from members of the scientific community of the former Soviet Union.
