The metal function of a commercial 0.3–0.3 wt% Pt–Re/Al 2 O 3 catalyst was characterized by temperature-programmed reduction, by H 2 and O 2 chemisorption, and by using methylcyclohexane dehydrogenation and n -heptane conversion as model reaction

The effect of reaction pressure in catalytic reforming was studied in a pilot reactor with a commercial Pt−Re/Al2O3 reforming catalyst and a hydrotreated naphtha from a North Sea crude. Reformate and hydrogen yields, research octane numbers (RON),

The reactions of propane with iodine have been evaluated theoretically in the temperature range 700–900 K. These calculations have been compared with test runs with propane/air in lithium hydroxide/lithium iodide melte. Thermodynamic and kinetic co

Calcium naphthenate deposition is among the most challenging obstacles to high production regularity for oilfields where acidic crude oils are produced. Until now it has generally been acknowledged that the deposit is made up of calcium soaps of the

At the Statoil-operated Heidrun-field in the Norwegian Sea, naphthenate deposits were first observed during a maintenance shutdown in September 1996. Thereafter the problem increased, and by the end of 1997 it was recognised as a constant threat agai

The amount of acidic crude oils produced worldwide is increasing. These oils introduce problems throughout the hydrocarbon value chain due to their high content of carboxylic acids, examples of which are naphthenate deposition in production facilitie
Publisher Summary Hydrotreating reactions of distillates and gas-oils are industrially performed in trickle bed reactors, on the scale of several meters in diameter and height. For the development of new catalysts and processes in the laboratory, a r

The vapour pressure and vapour compositions have been determined for the molten AlCl3-POCl3 system in the composition range 50–64 mol% AlCl3 and for temperatures in the range 170–270°C using a boiling point method and analyzing the boiled-off va
