摘要： Substantially all of the carbon dioxide is removed from a gas containing up to about 1% by volume carbon dioxide by subjecting the gas to a pressure swing adsorption process using as the adsorbent a single layer of zeolite having a silicon to aluminum atomic ratio in the range of 1.5 to 70. The process is particularly suitable for removing substantially all carbon dioxide and water vapor contained in air prior to subjecting the air to cryogenic distillation.

摘要： A process for producing a purified gaseous product from a gaseous feedstream such as air containing impurities is disclosed. The impurities such as hydrogen, water vapor, carbon monoxide and carbon dioxide are removed from the gaseous feedstream in a vessel having layers of adsorbents and oxidation catalysts. The placement of the hydrogen to water vapor conversion catalyst downstream of the step of contacting the feedstream with a catalyst to convert the carbon monoxide to the carbon dioxide and the step of removing the carbon dioxide from the feedstream improves not only performance but also the economies of the purification system.

摘要： Substantially all of the carbon dioxide is removed from a gas containing up to about 1% by volume carbon dioxide by subjecting the gas to a pressure swing adsorption process using a two layer adsorption system, wherein the first layer contains activated alumina and the second layer is a zeolite or a combination of zeolites having a silicon to aluminum atomic ratio of at least 1.5. The process is particularly suitable for removing substantially all carbon dioxide and water vapor contained in air prior to subjecting the air to cryogenic distillation.

摘要： A biorejuvenator includes a bio-oil formed from a mixture including a first biomass component and a second biomass component. A nitrogen content of the first biomass component exceeds a nitrogen content of the second biomass component, and a lipid content of the second biomass component exceeds a lipid content of the first biomass component. Preparing the biorejuvenator includes combining a first biomass component and a second biomass component, and co-liquefying the first biomass component and the second biomass component to yield the biorejuvenator. The biorejuvenator can be used as an asphalt modifier in an asphalt composition or as a coating for asphalt pavement.
