Abstract: Systems and methods are provided for partial upgrading of heavy hydrocarbon feeds to meet transport specifications, such as pipeline transport specifications. The systems and methods can allow for one or more types of improvement in heavy hydrocarbon processing prior to transport. In some aspects, the systems and methods can produce a partially upgraded heavy hydrocarbon product that satisfies one or more transport specifications while incorporating an increased amount of vacuum gas oil and a reduced amount of pitch into the partially upgraded heavy hydrocarbon product. In other aspects, the systems and methods can allow for increased incorporation of hydrocarbons into the fraction upgraded for transport, thereby reducing or minimizing the amount of hydrocarbons requiring an alternative method of disposal or transport. In still other aspects, the systems and methods can allow for reduced incorporation of external streams into the final product for transport while still satisfying one or more target properties.

Abstract: Ceramic monolith compositions are provided with improved stability under reaction conditions involving elevated temperatures. Such monoliths can be used, for example, in reverse flow reactors under high temperature reforming conditions, where the interior components of the reaction zone can be exposed to average temperatures of 1000° C. or higher while also being exposed to rapid oscillations in temperature of 100° C. or more in the presence of alternating oxidizing and reducing chemistries. The ceramic monolith compositions can be composed of materials that have improved ability to withstand conditions in severe reaction environments. Additionally or alternately, the ceramic monolith compositions can have structural features that reduce or minimize the tendency for the monolith to suffer structural failure under the conditions in severe reaction environments.
