  • Publication number: 20220185664
    Abstract: There is described a method of using a feedstock gas reactor. Reaction of feedstock and combustion gases in the reactor produces hydrogen through pyrolysis of the feedstock gas. At least some of a mixed product stream extracted from the reactor may be recycled to the reactor to drive further pyrolysis of the feedstock gas. A portion of the recycled mixed product stream may be recirculated back to a combustion chamber of the reactor, and a portion of the recycled mixed product stream may be recirculated back to a reaction chamber of the reactor.

  • Publication number: 20220185663
    Abstract: There is described a method of producing hydrogen and nitrogen using a feedstock gas reactor. Reaction of feedstock and combustion gases in the reactor produces hydrogen and nitrogen through pyrolysis of the feedstock gas. Parameters of the process may be adjusted to control the ratio of hydrogen to nitrogen that is produced such that it may be suitable, for example, for the synthesis of ammonia.

  • Publication number: 20220185954
    Abstract: A curative for epoxidized plant-based oils and epoxidized natural rubber is created from the reaction between a naturally occurring polyfunctional acid and an epoxidized plant-based oil is disclosed. The curative may be used to produce at least one of six different materials, wherein each type of material may be configured as a thermosetting elastomer that is crosslinked with ?-hydroxyester linkages. The materials may be configured as a leather-like material, a foam material, a molded elastomer, a coating, an adhesive, and/or a rigid or semi-rigid material. Illustrative articles made from any combination of the six materials may be recycled using a mechano-chemical process to de-crosslink the thermosetting elastomer.
