Abstract: We provide a method for removing contaminants from a gas, comprising: alternating input of the gas between two or more beds of adsorbent particles that comprise zeolite SSZ-36, zeolite SSZ-39, or zeolite SSZ-45; wherein the gas contacts one of the beds during an adsorption and a tail gas is simultaneously vented from another of the beds by desorption; wherein a contacting pressure is from about 345 kPa to about 6895 kPa and produces a product gas containing no greater than about 2 mol % carbon dioxide, at least about 10 wppm water, at least about 65 mol % of methane recovered from the feed gas, and at least about 25 mol % of ethane recovered from the feed gas; and wherein the tail gas is vented from the feed end of the beds. We also provide a method for removing a contaminant from a gas, wherein the gas contains hydrogen sulfide.

Abstract: A computer implemented method of matching ontologies is disclosed. The method includes, for each pair of entities of a first ontology and a second ontology, wherein each pair of entities includes a first entity from a first plurality of entities of the first ontology and a second entity from a second plurality of entities of the second ontology, and wherein the first entity and the second entity of each pair of entities is of a same data type: (1) determining a vector of similarities for the pair of entities; (2) determining a confidence score for the vector of similarities; (3) determining a relation score for each relation type based on the vector of similarities to measure relatedness between the first entity of the pair of entities and the second entity of the pair of entities; and (4) generating a mapping ontology based on the relation type, the relation score, and the confidence score of each pair of entities.

Abstract: Disclosed herein are processes for tandem alkene dehydrogenation/alkene dimerization using an iridium pincer complex catalyst on a support comprising magnesium silicates (e.g., Florisil®). The reaction process comprises providing an iridium pincer complex bound to a solid support comprising magnesium silicates; providing a gaseous alkane feedstock comprising at least one alkane; and contacting the gaseous alkane feedstock with the iridium pincer complex bound to the solid support in the presence of a hydrogen acceptor to form dimerized alkenes. The processes disclosed herein can accomplish facile, low-temperature tandem transfer dehydrogenation of alkanes and dimerization of alkenes with unprecedented TONs at a reasonable rate of conversion.
