| 20120015266 | CATALYST FOR A PROCESS FOR OBTAINING HYDROGEN THROUGH REFORMING HYDROCARBONS WITH STEAM, PROCESS FOR PREPARING THE CATALYST AND USE THEREOF IN THE PROCESS - The present invention relates to a catalyst for producing gaseous hydrogen current or hydrogen-rich currents through hydrocarbon reforming with water vapor. Said catalyst comprises at least one support, an active phase and at least two promoting agents, and is characterized in that it is a metal-type-supported solid in which the active phase comprises at least one transition metal chosen from group VIII, and at least one promoting agent chosen from the alkaline-earth or transition metals; and the support comprises at least one mixed oxide with a basic nature, and at least one promoting agent chosen from among the lanthanides group. The invention also has as an object the process for preparing the catalyst, as well as its use in the process for obtaining the hydrogen or hydrogen-rich gas from hydrocarbons, in different operating conditions and using various types of hydrocarbons. The catalyst to which this invention pertains has elevated activity and selectivity toward the gasification of hydrocarbons, as well as a high resistance to various deactivation mechanisms which the catalyst undergoes during the reforming process with water vapor. | 01-19-2012 |

| 20080302276 | VERY FAST SETTING CEMENTITIOUS COMPOSITION WITH HIGH EARLY-AGE COMPRESSIVE STRENGTH - A method of making a rapid setting composition for cement boards is disclosed. Compositions including portland cement, fly ash, gypsum, alkanolamine and phosphate are disclosed. A synergistic interaction between the alkanolamine and phosphate increases the effectiveness of accelerating reactions thus allowing for quick setting and increased early-age compressive strength compositions. | 12-11-2008 |
| 20100071597 | FLY ASH BASED LIGHTWEIGHT CEMENTITIOUS COMPOSITION WITH HIGH COMPRESSIVE STRENGTH AND FAST SET - A method of making a rapid setting lightweight cementitious composition with improved compressive strength for products such as boards is disclosed. The method mixes fly ash, alkali metal salt of citric acid and lightweight aggregate with water. Compositions which include fly ash, alkali metal salts of citric acid and lightweight aggregate are also disclosed. | 03-25-2010 |
