Patent number: 8398747Abstract: This invention relates in part to a process for producing high purity acetylene by withdrawing a crude acetylene stream from a storage source, and passing said stream through an adsorbent bed that contains layered adsorption media to selectively remove moisture, solvent and carbon dioxide from the stream, thereby producing the high purity acetylene. The adsorption media is regenerated in-situ. The high purity acetylene product is useful as a source material for depositing carbon and carbon-containing films in semiconductor applications.Type: GrantFiled: June 23, 2009Date of Patent: March 19, 2013Assignee: Praxair Technology, Inc.Inventors: Xuemei Song, Lloyd Anthony Brown, Thomas Thompson

Patent number: 8394177Abstract: This invention provides methods for separating gas components from a gas stream. The methods are particularly advantageous in that an environmentally friendly biomass absorbent is used to assist in the separation process. The invention is particularly suited to separate water soluble gas components from a gas stream. The water soluble gas components can be used to condition the biomass for additional use, such as a conditioned feed for a biofuel. In general, the conditioned biomass will have increased enzyme digestibility, making the conditioned biomass highly suitable as feedstock for biofuel production.Type: GrantFiled: June 1, 2010Date of Patent: March 12, 2013Assignee: Michigan Biotechnology InstituteInventors: Timothy J.
