Abstract: The alignment device or jig is utilized in aligning a shaft of a pelletizer perpendicular with a die face and includes a sensing/scraping assembly which is adapted to travel on a die face and scrape polymer drool off the die face until a scraping edge of the assembly is in constant contact with the die face during rotation of the jig on the shaft of the pelletizer. The scraping edge is mounted on the end of a rod which is spring biased toward the die face and which is axially movable in a bore in the jig and movement of the rod indicates nonperpendicularity of the shaft to the die face. After adjusting the skew of the shaft, cessation of movement of the rod in the bore in the jig will indicate a true perpendicularity of the shaft to the die face.

Abstract: A process for the manufacture of a phosphorus-vanadium oxide and a phosphorus-vanadium-co-metal catalyst suitable for the oxidation of butane to maleic anhydride is disclosed. The catalyst is prepared by reacting, in an aqueous medium, a vanadium compound, inorganic acid and, if used, a metal oxide. Ortho-phosphoric acid is then added to form a soluble vanadium-phosphorus or a vanadium-phosphorus-metal catalyst. The acidified water is removed and aliphatic alcohols and either aromatic acids or aromatic anhydrides, or a mixture of these, are added and the alcohols are removed. The solid phosphorus-vanadium, or phosphorus-vanadium-metal oxide is recovered under vacuum.

Abstract: Greater product yield and quality and continuous upgrading of shale oil with hydrogen-rich, purge mode off gases is attained by pulsing in situ retorts at different phases and intervals. In the process, flow of feed gases to the flame fronts of underground retorts are sequentially stopped and purged while continuously retorting the oil shale to enhance transfer of sensible heat from the combustion zones to the retorting zones and enlarge the separation between the combustion zones and the advancing fronts of the retorting zones. The flame fronts can be purged with steam, water, carbon dioxide, nitrogen, hydrogen, combustion mode off gases, purge mode off gases, reactor off gases, or combinations thereof. The combustion mode off gases and/or purge mode off gases can also be used as part of the feed gas or fuel gas.

Abstract: A process is provided to produce, stabilize, dedust and upgrade synthetic oil, such as shale oil. In the process, synthetic fuels, such as oil shale, tar sands and diatomite are retorted with heat carrier material to liberate an effluent product stream comprising hydrocarbons and entrained particulates of dust. In order to minimize polymerization of the product stream and agglomerate the dust, the product stream is stabilized, upgraded, and pretreated prior to dedusting, in a hydroprocessor, such as an ebullated bed reactor, with a hydroprocessing gas in the presence of a catalyst. The hydroprocessing gas can be hydrogen, scrubbed fractionator gases, or hydrocarbon-enriched hydroprocessor off gases.
