摘要： A method for assaying incompatible sediment in a blended heavy fuel oil is provided. The method is based on measuring total light absorption at 1600 nanometers wavelength, for example, of two or more samples blended to different viscosities, at least one such sample being at specification viscosity. The method may be used to control visbreaker severity so as to reduce the large ERT safety margin commonly used by refiners.
摘要翻译：提供了一种用于测定混合重油中不相容沉淀物的方法。该方法基于测量在1600纳米波长处的总光吸收，例如，混合到不同粘度的两个或更多个样品，至少一个这样的样品处于规定的粘度。该方法可用于控制抗溃疡剂严重性，以减少精炼商通常使用的大的ERT安全裕度。

摘要： Light olefins are catalytically converted to ethers, e.g., propylene is converted to diisopropyl ether, in a dual stage process in which product ether is recycled to a first stage reaction zone to significantly reduce the operating temperature of the olefin hydration/etherification reactions taking place in that zone. Alcohol produced in the first stage reaction zone undergoes conversion in the second stage reaction zone, e.g., by etherification with light olefin or by catalytic distillation, to provide additional product ether. The process contemplates the use of zeolites as olefin hydration/etherification catalysts.

摘要： Heavy petroleum oils such as resids are subjected to visbreaking in the presence of a hydroaromatic hydrogen donor solvent having an aromatic and alpha-to-aromatic proton content each of at least 20 percent of the total solvent hydrogen. The amount of donor solvent is from 0.1 to 50, preferably 0.1 to 20, weight percent of the heavy oil feed. The visbreaking may be carried out at relatively high severities as the use of the donor solvent reduces coke formation as well as producing a product of reduced viscosity, pour point and sedimentation characteristics. Reaction severity is usually in the range of 250 to 1500 seconds ERT at 800.degree. F. (427.degree. C.) but may range up to 15000 seconds ERT. Suitable solvents may be obtained from catalytic cracking process, for example, FCC cycle oils, slurry oils and main column bottoms.
摘要翻译：在油芳族氢供体溶剂存在下，将重质石油油（如残渣）进行减粘裂化，其具有芳族和α-至芳族质子含量，每个都占总溶剂氢的至少20％。供体溶剂的量为重油进料的0.1-50重量％，优选0.1-20重量％。减粘裂化可以在相当高的严重程度下进行，因为使用供体溶剂减少焦炭形成，以及生产具有降低粘度，倾点和沉降特性的产物。反应严重度通常在800°F（427°C）的250至1500秒的ERT范围内，但可能范围高达15000秒ERT。合适的溶剂可以从催化裂化过程获得，例如FCC循环油，浆料油和主塔底物。

摘要： A process for production of alcohol or ether by hydration of olefinic feedstock containing at least one lower alkene by contacting the olefinic feedstock and water in a hydration zone with porous solid metal oxide acidic olefin hydration catalyst under olefins hydration conditions. The process is characterized by the step of pretreating porous solid catalyst, such as acid zeolite, prior to contacting with the olefinic feedstock with a wetting agent containing at least one polar aliphatic oxygenated hydrocarbon to substantially wet said solid catalyst and sorb said wetting agent into pores of said solid catalyst. After initiating hydration reaction by feeding the olefinic feedstock and water, increased catalytic activity is obtained. The process is particularly useful for making isopropanol and DIPE from propene and water.

摘要： A solvent extract obtained from a conventional hydrocarbon oil solvent extraction process, e.g., one employing furfural as the extraction solvent, is cooled to a temperature providing, following a secondary decantation of the cooled extract, a pseudo raffinate containing most of the non-aromatics and a pseudo extract possessing a hydro-aromatic content of H.sub.alpha hydrogen of at least 20 percent of the total hydrogen content. The pseudo extract is ideally suited as a hydrogen-donor for a variety of refinery operations such as visbreaking. The pseudo raffinate is suitable as a co-feed for such catalytic cracking operations as fluidized catalytic cracking (FCC) and thermofor catalytic cracking (TCC) and can be recycled to the extraction unit to produce more lube oil.
