Over the past decades SINOPEC has been uninterruptedly engaging in the development and upgrading of deep catalytic cracking （DCC） technology for manufacturing propylene from heavy oil. Recently SINOPEC after having made a lot of progress in the area of oil refining at the molecular level has developed a new generation DMMC-1.type catalyst designed for the DCC process. The laboratory evaluation tests have shown that compared to the existing MMC-2 type catalyst that features the best comprehensive performance, the DMMC-1.type catalyst has increased the propylene yield by 2.2% with the propylene selectivity increased by 1.%. The said catalyst has improved its ability for heavy oil cracking and coke selectivity along with reduction of olefin content in gasoline to achieve a better product distribution and improve the product quality. The results of application of the said catalyst in a 650-kt/a commercial DCC unit at SINOPEC Anqing Branch Company have revealed that the DMMC- 1.catalyst demonstrated an enhanced capability for heavy oil cracking and could increase the total liquid yield to 84.56 m% from 83.92 m%, the LPG yield to 38.90 m % from 34.60 m %, the propylene yield to 1..80 m% from 1..37 m% and the propylene concentration to 45.91.m% from 44.91.m%, and reduce the coke yield from 7.61.m% to 7.05 m% and the olefin content in gasoline from 42.3 v% to 37.5 v%, resulting in an incremental profit amounting to 52.1. million RMB a year. This technology has further upgraded and developed the DCC technology which has been commanding a leading position among the industry peers.

To understand the influence of the diagenetic water medium on the isotopic compositions of thermogenic coalbed gas, both hydrous and anhydrous closed-system pyrolyses were performed at temperatures of 250°C to 650°C on an herbaceous marsh peat. Compared to the results of anhydrous pyrolysis, the hydrocarbon gases generated from hydrous pyrolyses have very different hydrogen isotopic compositions. However, the carbon isotopic compositions of the hydrocarbon gases became only slightly heavier in hydrous pyrolysis, compared to that from anhydrous pyrolysis. With the progress of thermal evolution from peat to a more advanced thermal maturity of vitrinite reflectance values（Ro） of 5.5% during the pyrolysis, the difference in the average δD value increased from 52‰ to 64‰ between the hydrous pyrolysis with saltwater and anhydrous pyrolysis and increased from 1.‰ to 29‰ between the hydrous pyrolysis with freshwater and anhydrous pyrolysis, respectively. The difference in the average δ^（1.）C value was only 1.–2‰ between the hydrous and anhydrous pyrolysis. The relationships between the δD values of the generated hydrocarbon gases and Ro values as well as among δD values of the hydrocarbon gas species are established. The close relationships among these parameters suggest that the water medium had a significant effect on the hydrogen isotopic composition and a minimal effect on the carbon isotopic composition of the hydrocarbon gases. The results of these pyrolyses may provide information for the understanding of the genesis of coalbed gas from herbaceous marsh material with the participation of different diagenetic water media.

Effect of combining the metals of group VI supported on H-ZSM-5 zeolite as catalysts for non-oxidative conversion of natural gas to petrochemicals

引用

Journal of Natural Gas Chemistry 2009年第1期18卷 71-77页

作者： A. K. Aboul-Gheit A. E. Awadallah Process Development Division Egyptian Petroleum Research Institute Nasr City P. O. Box 9540 Cairo 11787 Egypt

The most prestigious catalyst applied in natural gas （methane） non-oxidative conversion to petrochemicals is 6%Mo/H-ZSM-5. Chromium, molybdenum and tungsten are the group VI metals. Hence, in this work, 6%Mo/H-ZSM-5 was correlated with 3%Cr＋3%Mo/H-ZSM-5 and 3%W＋3%Mo/H-ZSM-5 as catalysts to examine their promoting or inhibiting effects on the various reactions taking place during methane conversion. The catalytic activities of these catalysts were tested in a continuous flow fixed bed reactor at 700℃ and a GHSV of 1.00 ml·g^-1.h^-1.Characterization of the catalysts using XRD, TGA and TPD were investigated. XRD and NH3-TPD showed greater interaction between the W-phase and the Bronsted acid sites in the channels of the zeolite than between Cr-phase and the acid sites in the zeolite.

Room temperature compression properties of Ti-51.l-(1.2)X and Ti-26Al-(1.2)X alloys (X=***, Mn, Fe, Co. Ni, Zr, Nb, Mo, Ta, Ga or Sn) were measured in order to examine how the compression deformability correlates with the site occupancies of the alloying elements in γ-TiAl and α2-Ti3Al. The results showed that, for the γ phase, the compression ratio is not related to the site preference of the alloying elements in a simple way. For the α2 phase, the following correlation was observed between the compression ratio and the site occupancies of the investigated elements, those which occupy Al sites decrease the deformability, while those occupying Ti sites (except V) improve the deformability of the α2 phase. Compression properties of dual-phase TiAl alloys based on Ti-46Al-(1. 3, 5)X were also measured at room temperature to test aHypothetica l mechanism of ductilization based on mechanical compatibility at phase *** was concluded that no simple relationship exists between the deformability of the dual-phase alloys and the properties of their constituent phases.

A homologous series of cationic surfactants were synthesized and characterized by spectral studies, mass, IR, 1. NMR, 1.C NMR, 2D NMR and elemental analysis. The surface activities of these amphiphiles were measured, including surface tension (γ), critical micelle concentration (CMC), effectiveness (pcmc), efficiency (PC20), maximum surface excess (Γmax) and minimum surface area (Amin) at 25℃. Adsorption and micellization free energies of these amphiphiles in their solutions showed a good tendency towards adsorption at the interfaces. The synthesized amphiphiles showed good antimicrobial activity.
