Abstract: Processes are described for isomerizing one or more C14-C24 alpha olefins to produce an isomerization mixture comprising one or more C14-C24 internal olefins comprising contacting an olefinic feed comprising the one or more C14-C24 alpha olefins with a catalyst under isomerization conditions, wherein the catalyst comprises a microporous crystalline aluminosilicate having an MWW framework. The resulting isomerization mixture typically exhibits a low pour point with maintained biodegradability properties as compared to the olefinic feed, and is particularly useful in drilling fluid and paper sizing compositions.

Abstract: The invention relates to approach temperatures and approach temperature ranges that are beneficial in operating a pyrolysis reactor, to pyrolysis reactors exhibiting a beneficial approach temperature, to processes for carrying out hydrocarbon pyrolysis in a pyrolysis reactor having a beneficial approach temperature. The pyrolysis reactor can be, e.g., a reverse-flow pyrolysis reactor, such as a regenerative reverse-flow pyrolysis reactor.

Abstract: Ebullated bed reactors may be used to synthesize olefin compositions exhibiting low sediment toxicity and favorable pour points. The olefin compositions are formed by isomerizing linear alpha olefins (LAOs) into linear internal olefins (LIOs), skeletal isomerized branched olefins, or any combination thereof. Methods for preparing olefin compositions comprising LIOs and, optionally, branched olefins may comprise: providing an olefinic feed comprising one or more LAOs, and interacting the olefinic feed with a plurality of catalyst particulates in an ebullated bed reactor to form an isomerized product. The catalyst particulates are effective to isomerize the one or more LAOs into one or more of LIOs, skeletal isomerized branched olefins, or combinations thereof. The isomerized product may be incorporated in drilling fluids, particularly those intended for subsea use, due to their favorable environmental profile and low pour points.
