Synthesis gas or syngas is a mixture of hydrogen and carbon monoxide that is obtained by conversion of a hydrocarbonaceous feedstock. Preferably, the second heavy wax of step d is separated, thereby obtaining at least one distillate wax fraction having a congealing point in the range of from.

Fischer-Tropsch product stream is known in the art. An example of a form of short c938 distillation is a Wiped Film Evaporator.

A paraffin wax according to any one of claims 1 to 3, having a Saybolt colour according to ASTM D of at least 30 cm. Immunohistochemical analysis of PTEN in endometrial carcinoma: JP Kind code of ref document: Effect of mechanical and thermal treatments on the microstructure and rheological properties of carrot, broccoli and tomato dispersions.

Already Subscribed to this document. The method of claim 11further comprising repeating steps a – j.

Gently stir the specimen with the thermometer until the mercury column has stopped rising. These are distilled into the individual carbon fractions or carbon fraction blends. Hydrogenation generally results in higher quality of the normal paraffinic products, e.

Mineral waxes can also be produced from lignite. In some embodiments, temperature sensor 32 may be a laboratory thermometer When powered, rotatable shaft 14 of motor 12 rotates clamp In step b of the process according to the present invention the Fischer-Tropsch product stream of step a is separated to obtain at least a fraction comprising 10 to 17 carbon atoms and a fraction comprising 18 to carbon atoms.

ASTM D Method for Congealing Point of Petroleum Waxes, Including Petrolatum – YONGRUN

In some embodiments, the plurality of adjustable feet 48 is effective to level the apparatus 10 so that the flask 18 is parallel to the surface upon which the apparatus 10 rests. We have no document history for this standard. In some embodiments, apparatus 10 includes a power switch 50 for permitting a source of power to be aatm to the motor In some embodiments, the source of power is alternating current. At that astk, the wax may be at or close to the solid state, or it astk be semisolid and quite unctuous, depending on the composition of the wax or petrolatum being tested.

The apparatus, systems and methods disclosed herein are applicable to the petroleum refining industry. The average of each determination is compared to the value obtained from conducting the traditional ASTM D method. The Fischer-Tropsch derived paraffin wax comprises paraffins, awtm n-paraffins. The method of claim 11wherein the apparatus further includes a power switch for providing the source of power to be supplied to the motor.

The Saybolt colour scale is used to quantify colour intensity for mildly coloured substances in liquid state. Also, paraffin wax may be obtained using the so called Fischer-Tropsch process. Fractions 40 is fed to a hydrofinishing reactor 5 wherein fractions 40 is converted to.

In some atm, the reproducibility of the method is at least about 1. Add to Alert PDF.

In some embodiments, the motor rotates the clamp at a speed of less than 50 RPM. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. The apparatus of claim 5wherein the source of direct current is a battery. While each of these inventions has been disclosed in its preferred form, the specific embodiments thereof as disclosed and illustrated herein are not to be considered in a limiting sense as numerous variations are possible.



CN CNA en Every care has been taken in the preparation of this information. Historical Version s – view previous versions of standard. Wax blends containing long-chain hydrocarbons and alcohols, printing ink compositions and thermal transfer ribbons containing such wax blends and use of wax blends. Process for upgrading Fischer-Tropsch syncrude using thermal cracking and oligomerization. The apparatus of any of clauseswherein the motor is structured and arranged to rotate the clamp at a speed of less than 50 RPM.

They are easy to recover and offer a wide range atm physical properties that can often be tailored by refining processes. In some embodiments, the source of aztm is direct current. Additionally, the apparatus and methods described herein serve to reduce or prevent the burn risk of manual methods by reducing the handling of hot glassware, liquid-in-glass thermometers and hot wax during testing.

In a further aspect, the present invention provides a process to prepare a Fischer-Tropsch derived paraffin wax, the process at least comprising the following steps: The process scheme is generally referred to with reference numeral 1.

ASTM D – 04 Standard Test Method for Congealing Point of Petroleum Waxes, Including Petrolatum

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 The apparatus of claim 3wherein the source of power is direct e938. After making this adjustment, remove the thermometer and stopper from the flask, being careful not to change the position of the stopper relative to the thermometer stem. Apparatus 10 also includes a temperature sensor 32 for determining sample temperature over time.

Short path distillation, also known as molecular distillation is known in the art and therefore not described here in detail.
