Moreover, an object of the present invention is to provide an efficient method for preparing refined paraffin wax product in a high yield.

The test results obtained are compared below in Table 1. The present invention provides a paraffin wax and a process to prepare said paraffin wax. Microcrystalline wax contains substantial proportions of branched and cyclic saturated hydrocarbons in addition to normal alkanes.

This standard is also available to be included in Standards Subscriptions. Process for upgrading Fischer-Tropsch syncrude using thermal cracking and oligomerization. In some embodiments, flask 18 may be an Erlenmeyer flask These observations indicate that the obtained refined Fischer-Tropsch paraffin wax can be advantageously used in applications such as candles, hot melt adhesives, crayons, packaging, and PVC extrusion lubricants.

An advantage of said process according to the present invention is that by distilling the Fischer. Fractions 40 is fed to a hydrofinishing reactor 5 wherein fractions 40 is converted to.

The apparatus was kept on a lab bench and the thermometer was leveled with respect to the ground. The rotation speed of the apparatus was maintained at one revolution every seconds rpm.

Wax blends containing long-chain hydrocarbons and alcohols, printing ink compositions and thermal transfer ribbons containing such wax blends and use of wax blends. In some embodiments, the mouth 26 of the Erlenmeyer flask 18 may be provided with a axtm lip 28 that can be closed using a rubber stopper 30or similar.

The results obtained using ASTM Test Method D are usually lower than the results obtained by Test Method D, the amount of the deviation varying with the axtm of the petroleum wax. Instead, the scope of the invention is defined by the appended claims. When powered, rotatable shaft 14 of motor 12 rotates clamp The reduction in glass handling also helps to reduce glassware injury risk. We have no document history for this standard.

Process according to claim 7, wherein the heavy wax of step is separated in step e by short path distillation at a pressure between 0.

As those skilled in the art recognize, Erlenmeyer flask 18 has a wide base 20with sides 22 that taper upward to a short vertical neck Tropsch derived waxes is for example described on page in the “Handbook of Commercial Catalysts. A new separation process d38 polyolefin resins. It is a translucent crystalline material in the solid state and a yellow, clear liquid when molten. In some embodiments, the method also includes repeating steps – Effect of mechanical and thermal treatments on the microstructure and rheological properties of carrot, broccoli adtm tomato dispersions.

The apparatus of claim 3wherein the source of power is direct current. Suitably, the first light wax fraction is obtained as top cut of the vacuum distillation, the second light wax fraction is obtained as a side cut of the vacuum distillation and the third light wax fraction is obtained as heavier side cut of the vacuum distillation.

Tropsch derived feed without a preceding hydrogenation step results in paraffin waxes having high Saybolt colours. It is believed that the following claims particularly point out certain combinations and subcombinations that are directed to one of the disclosed inventions and are novel and non-obvious. Fischer-Tropsch derived paraffin wax comprises more than 85 wt. The fraction 10 is fed to a hydrogenation reactor 8 wherein fraction 10 is converted to a hydrogenated fraction 90 comprising 10 to 17 carbon atoms.

The apparatus of clause 1, further comprising a housing for mounting the motor within. All such waxes have the same basic structure, but the various production processes yield products with distinctly different properties, and these have a major impact on the use of products.

These are distilled into the individual carbon fractions or carbon fraction blends. It is derived from petroleum via a carefully controlled refining process and is primarily comprised of a mixture of straight chain normal paraffin and branched, iso-paraffin hydrocarbons. Use of infrared spectroscopy to produce high lubricity, high stability, Fischer-Tropsch diesel fuels and blend stocks. Alternatively, in some embodiments, the source of power is direct current. ASTM Proficiency Testing Programs PTP are statistical quality assurance ast that enable laboratories to assess their performance in conducting test methods within their own laboratories when their data are compared against other laboratories that participate worldwide in the same program.

Synthesis gas or syngas is a mixture of hydrogen and carbon monoxide that is obtained by conversion of a hydrocarbonaceous feedstock. US USA1 en The earliest production of montan wax on a commercial scale was in Germany during the latter half of the nineteenth century.

A paraffin wax according to any one of claims 1 to 4, having asm oil content according to ASTM D of less than 0. The brief pause time is not to d98 included in the 2 to 3-s rotation time.
