Conversion of high carbon refinery by-products. Annual technical report, fiscal year 1995 (October 1994--September 1995)

PDF Version Also Available for Download.

Description

The overall objective of the project is to demonstrate that a partial oxidation system, which utilizes a transport reactor, is a viable mans of converting refinery wastes, byproducts, and other low-value materials into valuable products. The primary product would be a high quality fuel gas, which could also be used as a source of hydrogen. The concept involves subjecting the hydrocarbon feed material to pyrolysis and steam gasification in a circulating bed of solids. Carbon residue formed during pyrolysis, as well as metals in the feed, are captured by the circulating solids, which are returned to the bottom of the ... continued below

Description

The overall objective of the project is to demonstrate that a partial oxidation system, which utilizes a transport reactor, is a viable mans of converting refinery wastes, byproducts, and other low-value materials into valuable products. The primary product would be a high quality fuel gas, which could also be used as a source of hydrogen. The concept involves subjecting the hydrocarbon feed material to pyrolysis and steam gasification in a circulating bed of solids. Carbon residue formed during pyrolysis, as well as metals in the feed, are captured by the circulating solids, which are returned to the bottom of the transport reactor. Air or oxygen is introduced in this lower zone and sufficient carbon is burned, sub-stoichiometrically, to provide the necessary heat for the endothermic pyrolysis and gasification reactions. The hot solids an gases leaving this zone pass upward to contact the feed material and continue the partial oxidation process. At the end of FY94, a limited number of pyrolysis runs were made using an oil in water emulsion of Hondo crude as the feed material. It was intended to conduct these tests in the fully integrated partial oxidation mode. At the completion of the tests, it was concluded that the reactor configuration was not suitable for handling highly coking liquid hydrocarbon feeds. The decision was made to design and build a new reactor which, in addition to a better feed injection systems, includes other design features that improve the performance and reliability of the unit. The new design is also more suitable for integrated partial oxidation testing. The design, construction, and start-up of this reactor is described.
