Abstract: The present invention discloses a process for preparation of high silica Y-zeolite by utilizing waste silica source. The steps include preparing a dilute nucleating agent, preparing a dense nucleating agent by mixing sodium silicate, sodium aluminate, deionized water and sodium hydroxide. Further, preparing an aluminosilicate gel by mixing the dilute nucleating agent with sodium silicate, aluminium sulphate, deionized water and dense nucleating agent, followed by crystallizing the aluminosilicate gel filtering and washing to obtain a Y-zeolite cake. The Y-zeolite is ammonia exchanged, dried and calcined to obtain high silica Y-zeolite.

Abstract: The present disclosure relates to a 13X zeolite, a 13X zeolite adsorbent and a synthesis method thereof. Wherein, the synthesis method includes preparing a seed material by mixing sodium aluminate, sodium silicate, NaOH into water to get a seed mixture, stirring the seed mixture and aging. Then preparing the 13X zeolite by mixing sodium aluminate, sodium silicate, NaOH into water, followed by 0-5 wt. % addition of the seed material to obtain a gel mixture. Stirring the said gel mixture for 1 hour and crystallization of the gel mixture, then a filtration step and a washing step is performed to obtain a 13X zeolite cake. Further, the 13X zeolite cake is dried at 120° C. for 24 hours, then crushed and grinded to obtain a 13X zeolite powder. The 13X zeolite adsorbent is prepared by binding the 13X zeolite powder with a binder.

Abstract: Methods and systems are provided for generating a flight profile for search and rescue (SAR) operations. The method comprises monitoring flight parameters of an in-flight aircraft engaged in star operations through the aircraft's flight management system (FMS). The flight parameters are transmitted to a ground-based FMS that accesses a terrain database and a real-time weather database. With this information, the ground-based FMS generates a star flight profile for the aircraft. The flight profile is then transmitted to the in-flight aircraft's FMS.
