摘要： On décrit des procédés de fabrication améliorée de brai de pétrole enrichi, de précurseurs de fibres de carbone, de fibres de carbone et de fibres de graphite. L'amélioration réside dans l'utilisation d'un évaporateur à film balayé surélevé (105) dans un système d'évaporateur à film balayé comprenant l'évaporateur à film balayé (105) et un moyen de récupération (119) de brai enrichi, tel qu'une pompe volumétrique (119), pour produire un brai enrichi à partir de brai catalytique, et dans la régulation des conditions de fonctionnement de l'évaporateur à film balayé pour obtenir le brai enrichi désiré. L'évaporateur à film balayé (105) est situé à une distance spécifique au-dessus du moyen de récupération (119) de brai enrichi. La distance verticale entre la sortie de l'évaporateur (105) et l'entrée du moyen de récupération (119) de brai enrichi est comprise entre 3 et 15 mètres environ, de préférence entre 6 et 15 mètres. De préférence, l'évaporateur à film balayé (105) est chauffé par un milieu de transfert de chaleur Syltherm de Dow Chemical ou un dérivé ou un équivalent de celui-ci.

摘要： Until now, it has not yet been succeeded to prepare high performance carbon fibers having satisfactory strength from heavy oils of coal or petroleum origin. We now succeeded to prepare an excellent itnermediate pitch which allows the preparation of high performance carbon fibers having tensile strength of higher than 300 Kg/mm² and Young's modulus of 50 ton/mm².
The intermediate pitch can be obtained by heating a heavy oil of coal or petroleum origin in a tubular heater under a specific conditions, and then flash distilling the heater effluent in a flash distillation column under a specific condition so as to remove lighter fractions and recovering heavy fraction from the column bottom as the intermediate pitch. The process for the preparation of the intermediate pitch is simple and economical and allows continuous production without fluctuation of quality of the intermediate pitch. The intermediate pitch is also suitable for the production of higher density carbon products.摘要翻译： 迄今尚未成功制备具有令人满意的煤或石油来源重油的高性能碳纤维。 我们现在可以成功制备出优良的中纬节距，可以制备抗拉强度高于300Kg / mm2，杨氏模量为50吨/平方毫米的高性能碳纤维。 中间沥青可以通过在特定条件下在管状加热器中加热煤或石油来源的重油，然后在特定条件下将闪蒸蒸馏塔中的加热器流出物闪蒸，以除去较轻馏分并重新沉积 从柱底部的分数作为中间间距。 制备中间沥青的方法简单经济，可连续生产，而不会造成中间沥青质量的波动。 中间沥青也适用于生产高密度碳产品。

摘要： The process for treating a hydrocarbon-based heavy residue (1), in particular bituminous residues with a high asphaltene content, comprises the following operations: A) bringing the heavy residue to be treated to a temperature within the range of 325-500° C.; B) subjecting the heavy residue to be treated to a substantially adiabatic expansion in an environment at a pressure equal to or lower than about 0.1 bara, and at a temperature equal to or lower than 450° C., so as to separate, from the heavy residue to be treated, a first less volatile fraction (17) having a boiling point at atmospheric pressure equal to or higher than 540° C. and whose solid and/or anhydrous residue prevalently contains asphaltenes insoluble in pentane and/or other residues insoluble in tetrahydrofuran. It allows a more effective flushing, and also to actuate the process in an extremely simple plant and without centrifugations.

摘要： Methods are provided for forming an asphalt fraction corresponding to a blend of asphalts, the asphalt fraction having at least one property that is unexpectedly better than the expected property value based on the individual asphalts used in the blend. The unexpectedly beneficial blends of asphalts are formed in part by including an effective amount of a Napo crude oil or crude fraction in the feed used to form the asphalt fraction. For some asphalt blends, including an effective amount of a Napo crude in the feed can allow for production of an asphalt with a low temperature performance grade that is lower than the predicted value by at least 0.5° C., such as at least 0.75° C. or at least 1.0° C.

摘要： There are provided improved processes for the manufacture of enriched pitches, carbon fiber precursors, carbon fibers, and graphite fibers. The improvement comprises employing an elevated wiped-film evaporator (105) in a wiped-film evaporator system comprising the wiped-film evaporator (105) and a means for recovering enriched pitch (119), such as a positive displacement pump (119), to form an enriched pitch from catalytic pitch and regulating the operating conditions of the wiped-film evaporator system to provide the desired enriched pitch. The wiped-film evaporator (105) is located a specific distance above the means for recovering enriched pitch (119). The vertical distance between the outlet of the wiped-film evaporator (105) and the inlet of the means for recovering enriched pitch (119) is within the range of about 3 to about 15 meters, preferably about 6 to about 15 meters. Preferably the wiped-film evaporator (105) is heated with Dow Chemical Syltherm heat transfer media or its derivatives or equivalents.

摘要： A method of making a high softening point coal tar pitch using high efficiency evaporative distillation, as well as the uses and applications of such pitch. According to the method, a feed coal tar pitch having a softening point in the range of 70°C to 160°C is fed into a processing vessel wherein the processing vessel is heated to a temperature in the range of 300°C to 450°C and wherein a pressure inside the processing vessel is in the range of 5 Torr or less. An output coal tar pitch is withdrawn from the processing vessel. The output coal tar pitch has a softening point in the range of 140°C to 300°C and has less than 5% mesophase.
