  • Patent number: 4547284
    Abstract: 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.

  • Patent number: 4439313
    Abstract: 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.

  • Patent number: 4329525
    Abstract: A compound is chlorinated with chlorine to produce chlorinated product and hydrogen chloride byproduct. Recovered hydrogen chloride byproduct is contacted with oxygen and a molten salt mixture containing the higher and lower valent chlorides of a multivalent metal, such as cuprous and cupric chloride, to effect recovery of the hydrogen chloride by enriching the molten salt content of the higher valent chloride. The molten salt, enriched in higher valent chloride, is then dechlorinated by use of a stripping gas, preferably hydrogen chloride, to produce a gaseous effluent containing stripped chlorine and the stripping gas, which is then recycled to the chlorination step. The presence of stripping gas, as a diluent, improves the chlorination operation.

  • Patent number: 4316793
    Abstract: Coal is catalytically hydroliquefied by passing coal dispersed in a liquefaction solvent and hydrogen upwardly through an expanded catalyst bed in a stream having a cross-sectional flow area of no greater than 255 inches square, with the stream through the catalyst bed 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.

  • Patent number: 4148709
    Abstract: In the hydroliquefaction of a sub-bituminous and/or lignitic coal, the inlet temperature to the hydroliquefaction zone is maintained at a temperature higher than those previously employed by providing recycle of hot liquid from the outlet portion of the hydroliquefaction zone. In this manner, the hydroliquefaction is operated at higher average temperatures, and total reaction volume is reduced, thereby reducing overall costs.
