摘要： A petroleum coke of unusually high-crystalline texture and of high purity is produced from a low-sulfur petroleum material by a process including a preheat-treating step for removing non-crystalline substances contained in the material as pitch or coke and a coking step wherein a heavy oil derived from the preceding step is coked in a coking crystallizer in such a manner that pitch-like heavy oil downwardly flows and is progressively accumulated and coked therein while gaseous light hydrocarbons are discharged at the upper part of crystallizer whereby the coking is conducted with a high growth and high orientation of coke crystals formed.

摘要： A high-crystalline petroleum coke is produced from low-sulfur petroleum feedstock such as virgin crude oil, distillation residuum and cracked residium by subjecting the feedstock to preheat treatment under specific conditions to effect cracking and soaking thereof, subjecting the preheat-treated feedstock to flash distillation to remove non-crystalline substances contained therein as pitch and to recover distillate, fractionating the distillate to provide a heavy residue and subjecting the heavy residue to a delayed coking under specific conditions to produce the desired coke which has a coefficient of thermal expansion of less than 1.0 .times. 10.sup.-6 /.degree. C over 100.degree.-400.degree. C.

摘要： A high crystalline coke can be prepared by heat-soaking a petroleum feedstock in the presence of added dissolved sulfur, heating to effect controlled thermal cracking thereof, separating non-crystalline substances as pitch, recovering a heavy cokable residue from the pitch free feed, and subjecting the residue to delayed coking.

摘要： Any kind of virgin, low-sulfur crude oil is directly treated in a two-stage delayed coking process for yielding non-crystalline coke in the first stage and high-crystalline coke in the second stage, which process comprises preheating the crude oil in a tube heater to 460.degree. - 520.degree.C under 5-20 kg/cm.sup.2 G, maintaining the oil therein at that temperature for 30 - 500 seconds to allow the oil to be heat-soaked, subjecting the oil to first delayed coking under relatively mild conditions and subjecting the uncoked heavy residual oil to second delayed coking under relatively severe conditions.

摘要： In the production of high-density carbon materials directly from a green coke without the aid of a binder by a process comprising molding a finely pulverized green coke as such by pressing in a mold, demolding and baking the molded green coke to form a sintered carbon material and, if desired, graphitizing the sintered material, a serious disadvantage that there occur laminar cracks in the molded green coke at the demolding stage is avoided by molding the green coke in the form of a composition comprising a finely pulverized green coke in intimate admixture with a small amount of water or a certain monohydric alcohol.

摘要： A petroleum pitch or coke of a high purity is produced from a petroleum heavy residue such as distillation and cracked residua, asphalt and pitch by such treatment of the residue prior to a conventional pitching or coking treatment that the residue is treated with hydrogen in the absence of a catalyst under a hydrogen pressure of 20.about.200 Kg/cm.sup.2 under a gradual heating up to a final temperature of 350.degree..about.400.degree. C. so as to heat the residue from 150.degree. C. to 300.degree. C. over 30 to 120 minutes and then from 300.degree. C. to the final temperature over 10 to 60 minutes. The non-catalytic hydrogen treatment is called "hydrogenation refining step", which gives a refined pitching/coking feedstock from which a petroleum pitch or coke of extra high purity is derived.
摘要翻译：石油沥青或高纯度焦炭是通过石油重残余物如蒸馏和裂化残渣，沥青和沥青在常规的俯仰或焦化处理之前进行处理而残留物进行处理，在不存在的情况下用氢处理残留物的催化剂在20分压200Kg / cm 2的氢气压力下，逐渐加热至350℃的最终温度400℃，以将残余物从150℃加热至300℃，30℃以上 120分钟，然后从300℃至最终温度10-60分钟。非催化氢处理被称为“氢化精炼步骤”，其提供了精炼的俯仰/焦化原料，从其中得到石油沥青或超高纯度的焦炭。
