  • Patent number: 10654817
    Abstract: Novel 1-oxa-4-azonium cyclohexane salts are described. These compounds can be used as structure directing agents, and they overcome many of the typical problems associated with OSDA synthesis and subsequent zeolite synthesis. Methods for synthesis of the 1-oxa-4-azonium cyclohexane salts from a variety of starting materials are also described. A substituted hydrocarbon is added to water to form a mixture, and a 1-oxa-4-azacyclohexane derivative is then added. The reaction mixture stirred until a solution containing the 1-oxa-4-azonium cyclohexane salt is obtained.

  • Patent number: 10577291
    Abstract: A method for producing jet-range hydrocarbons includes passing a stream comprising renewable C4 olefins to an oligomerization reactor containing a zeolite catalyst to produce an oligomerized effluent, separating the oligomerized effluent to produce a jet range hydrocarbon stream and a recycle stream comprising C8 olefins, and passing at least a portion of the recycle stream to the oligomerization reactor. A first at least about 10% of the jet-range hydrocarbon stream hydrocarbons boil between n-octane and n-undecane and wherein a second at least about 10% of the jet-range hydrocarbon stream hydrocarbons boil between n-dodecane and n-pentadecane.

  • Patent number: 10563135
    Abstract: Processes for oligomerizing olefins to produce diesel. The oligomerization zone temperature is controlled to counteract catalyst deactivation caused by coking, by contaminants such as cyclo C5 and/or cyclo C6 hydrocarbons, or both. The temperature is increased in increments to ensure that that the oligomerization zone is producing product at a target product yield with a target product quality, which may be measured by a product cetane number. The target product yield is at least 50 wt % and a target product cetane number may be at least 35.

  • Patent number: 10332210
    Abstract: Improved computer modeling techniques, and uses thereof, are described herein. A set of unstructured textual data is received. Certain textual data is removed from the set of unstructured data to form an initial vocabulary set of textual data. One or more bigrams are added to the vocabulary set of textual data to form a final vocabulary set of textual data. The final vocabulary set of textual data is divided into a plurality of subsets of textual data based on type. A model is trained using each of the plurality of subsets of textual data to form a plurality of trained models, each corresponding to one of the types.
