Sear, T. N. Petroleum Rev.. Feb. 1995, 49, (5771, 58, 60. In today’s climate the customer differentiates‘behcen suppliers as much by price as by brand. Minimisation of total supply chain costs therefore remains a high priority for petroleum product marketing companies. The article describes key logistrcs planning decisions facing the marketing company. The role of Logistics Planning Models in supply chain optimisation and marketing strategy are indicated.

The oil outuut for the country has tripled in the last 10 years and further expansion, is well as gas growth is p&ted. However, wtiile new discoveries are still being made, some foreign companies have chosen to leave and go elsewhere.
Derived Liquid Fuels
The effects of process variables on the activity of a CoMZSM-5 zeolite bifunctional catalyst for the conversion of syngas to hydrocarbons were studied. The catalyst was repared by incipient-wetness impregnation from aqueous solutions of wba Pt and thorium mtrate, the latter used as promoter. The reactions were carried out in a fixed-bed integral reactor.

Coal slurry and solvent is liquefied in the presence of catalyst under hi@pressure of H, atmosphere with irradiation of ultrasonic wave for a period of time which is automated by pre-measuring viscosity of the slurry from the properties of the solvent followed by determining proper time from the viscosity and the amounts of the slurry.

Elemental analysis with a high energy charged-particle beam is a powerful analytical tool that has moved out of the realm of the specialized ‘nuclear’ laboratory and found widespread use among researchers in many different areas is described. 95102449 Aqueous organic chemistry. 8. Reactlvlty of blaryls Siskin, M. er aZ., Energy & Fuels, Mar.-Apr. 1995, 9, (2), 331-343. Biphenyl, or more accurately biaryl, linkages represent the most refractory cross-links in fossil fuel resources. They are essentially unreactive thermally and in supercritical water at 4@C. Many bia$s do, however, undergo bond cleavage and heteroatom removal under reducing conditions in supercritical water. 2-Arylpyridines, -quinolines, and -indoles are most reactive in 15% aqueous formic acid whereas the corresponding 2-arylthiophene and -benzothiophene derivatives are more reactive in 15% aqueous sodium formate. Major hydrocarbon products are benzene and naphthalene and their C,-C, alkylatcd derivatives. In most cases where conversion is not quantitative after lhr at 460°C the product slate consists of hydrogenated and cleaved products which, given more reaction time, are on the pathway toward complete heteroatom removal.

Coal liquefying reaction inside a preheater, swelling and dissolving and collapsing of coal particles, changes of viscosity and heat transfer coefficients of coal slurries, coal swelling during heating, and swelling in improving coal liquefaction characteristics.
Corn arlson by g.c.-m.8. of llquefactlon extracts 95102457 from coal maceraPconcentrates Brodzki, D. et a& Fuel, Mar. 1995, 74, (3), 407-415. Differences between the compositions of partly hydrocracked hexane-soluble extract fractions from the liquefaction of maceral wncentrates were investigated by gas chromatography-mass spectrometry. The technique identifies components within only a relatively narrow range of molecular masses, but some systematic differences were nevertheless observed. Dibenzofuran derivates were significantly more abundant in extracts derived from inertinite wncentrate than in liptinite or vitrinite extracts. Within the retention time interval where dibenzofiuan and its derivatives were identified in inertinite extracts, products prepared from liptinite and vitrinite concentrates were found primarily to contain biphenyls and acenaphthene derivatives.

Guerrero-Ruiz. A. et al.. Fuel. Feb. 1995. 74. (21. 279-283. Carbon-supported one-&mpon&t (Fe, Ru, ‘Pt) andtwo-component (FeRu and FePt) catalysts were used for hydrodenitrogenation of pyridine (HDN) at 3.0 MPa and 573K. The Fe catalyst was less active for pyridine wnversion and less selective for the formation of n-pentane than the noble metal catalyst were. For the two-component catalysts, activity was closely related to that of the noble metal component, although the C, hydrocarbon distribution was intermediate between that for the single components. Photoelectron spectra of sulphided and used catalysts showed that iron and ruthenium monowmponent catalysts are sulphided to a large extent, but platinum preserves in part its metallic character, although the situation differs from the platinum-iron catalysts.
