    Abstract: An apparatus and process for passivating catalysts wherein an inert gas is used to administer a precise, measurable amount of passivating agent to a catalyst in a substantially safer manner than conventional means. The inventive apparatus at least includes a first container comprising at least one inert gas, a second container comprising at least one passivating agent, and a reactor comprising at least one catalyst, the first container, second container, and reactor being fluidly connected by a plurality of conduits. The inventive process at least includes pressurizing a first container with an inert gas, filling a second container with passivating agent, providing a reactor containing a passivatable catalyst, mixing the inert with the passivating agent, forming a mixture of passivating agent and inert gas, and introducing the mixture of passivating agent and inert gas into the reactor.

    Abstract: Transition Metal Sulfides (TMS), such as molybdenum disulfide (MoS2), are the petroleum industry's “workhorse” catalysts for upgrading heavy petroleum feedstocks and removing sulfur, nitrogen and other pollutants from fuels. We have developed an improved synthesis technique to produce SLTMS catalysts, such as molybdenum disulfide, with potentially greater activity and specificity than those currently available. Applications for this technology include heavy feed upgrading, in-situ catalysis, bio-fuel conversion and coal liquefaction.
