Title: Dennis Leppin: Innovator in Gas Processing Technologies
Introduction
Dennis Leppin, a prominent inventor based in Chicago, IL, has made significant contributions to the field of gas processing technologies. With an impressive portfolio of 13 patents to his name, Leppin's work primarily focuses on the conversion and treatment of gases, underscoring his innovative approach to solving complex environmental challenges.
Latest Patents
Two of Dennis Leppin's most notable patents include:
1. **Scavenging and Tailgas Process** - This groundbreaking process addresses the removal of sulfur dioxide from hydrogen sulfide-containing gas. By utilizing a bubble tower, Leppin's method effectively overcomes the process control difficulties associated with traditional methods. The process involves feeding a solvent into the bubble tower, where it interacts with sulfur dioxide and hydrogen sulfide to create water and elemental sulfur. The elemental sulfur is then collected and discharged from the bottom of the tower, while the hydrogen sulfide-depleted gas exits from the top.
2. **Method for Producing Methane from Biomass** - This multi-stage method and apparatus represent a pioneering approach to producing methane from biomass. In this patented invention, biomass undergoes hydropyrolysis within a reactor vessel that contains molecular hydrogen and a deoxygenating catalyst. The resulting output is additionally processed using a hydroconversion catalyst, leading to a water-gas-shift process that generates a mixture of hydrogen, carbon monoxide, and methane. Ultimately, the components are separated to yield a product stream consisting almost entirely of methane.
