摘要： A nitrogen containing feedstock is hydrodenitrified by passing the feed through at least two hydrodenitrification zones, with ammonia produced in the hydrodenitrification being purged from the system prior to the last hydrodenitrification zone to maintain a low ammonia partial pressure in the last hydrodenitrification zone. The ammonia is preferably purged by stripping ammonia from the liquid portion of the effluent withdrawn from the next to last hydrodenitrification zone. Improved denitrification is obtained by maintaining a low ammonia partial pressure in the last hydrodenitrification zone.

摘要： Arsenic is removed from a hydrocarbon containing arsenic as an impurity; e.g., shale oil, by contact with hydrogen in the presence of a contact material, such as coke, to deposit the arsenic on the contact material. The arsenic deposited on the contact material is subsequently reacted with an iron compound to produce an iron-arsenic compound suitable for disposal.

摘要： Coal is catalytically hydroliquefied by passing coal dispersed in a liquefaction solvent and hydrogen upwardly through a plurality of parallel expanded catalyst beds, in a single reactor, in separate streams, each having a cross-sectional flow area of no greater than 255 inches square, with each of the streams through each of the catalyst beds having a length and a liquid and gas superficial velocity to maintain an expanded catalyst bed and provide a Peclet Number of at least 3. If recycle is employed, the ratio of recycle to total feed (coal and liquefaction solvent) is no greater than 2:1, based on volume. Such conditions provide for improved selectivity to liquid product to thereby reduce hydrogen consumption. The plurality of beds are formed by partitions in the reactor.

摘要： In the delayed coking of a coking feedstock wherein the feedstock is continuously heated in a coking heater and introduced into a coke drum, the heater is operated to provide a coke drum temperature of from 415.degree. to 455.degree. C., and, after filling of the drum to the desired level, feedstock introduction is discontinued and the coke drum contents are heated at a temperature of 450.degree. C. to 500.degree. C., and which heating temperature is at least 10.degree. C. greater than the coking temperature, by passing a non-coking vapor through the contents of the drum to reduce the volatile combustible matter content to a value of 4% to 10% by weight and thereby reduce the CTE of the formed coke. The process is applicable to the production of needle coke from various kinds of feedstocks, in particular from a petroleum feedstock wherein the feedstock is initially treated by thermal soaking in the presence of sulfur, followed by thermal cracking to increase the aromaticity. Noncrystalline substances may be removed prior to coking to further improve the process.
