  • Publication number: 20240010492
    Abstract: The invention includes a gas processing system for transforming a hydrocarbon-containing inflow gas into outflow gas products, where the system includes a gas delivery subsystem, a plasma reaction chamber, and a microwave subsystem, with the gas delivery subsystem in fluid communication with the plasma reaction chamber, so that the gas delivery subsystem directs the hydrocarbon-containing inflow gas into the plasma reaction chamber, and the microwave subsystem directs microwave energy into the plasma reaction chamber to energize the hydrocarbon-containing inflow gas, thereby forming a plasma in the plasma reaction chamber, which plasma effects the transformation of a hydrocarbon in the hydrocarbon-containing inflow gas into the outflow gas products, which comprise acetylene and hydrogen. The invention also includes methods for the use of the gas processing system.

  • Patent number: 11285427
    Abstract: The invention includes methods for removing higher acetylenes from a gaseous stream that includes a hydrogen fraction and a non-hydrogen fraction, wherein the gaseous stream includes less than about 4% in total of diacetylene and vinylacetylene, where the method includes the following steps: (i) an adsorption that passes the gaseous stream at a preselected superficial linear gas velocity across an adsorption bed supported within an enclosure, the adsorption bed containing a crystalline porous ceramic adsorbent to adsorb the higher acetylenes onto the adsorbent, thereby producing a saturated adsorption bed and a purified gaseous stream including less than about 25 ppm of diacetylene that regenerates the saturated adsorbent bed by passing a regeneration gas across the saturated adsorption bed to desorb the higher acetylenes retained thereupon, thereby producing a regenerated adsorbent bed and a contaminated gas stream bearing the higher acetylenes; and (iii) a purging step that removes the contaminated gas stre
