The performance of the adsorption cooling system using the zeolite 13X/CaCl2 composite adsorbent was studied using a numerical simulation. The novel zeolite 13X/CaCl2 composite adsorbent with superior adsorption properties was developed in previous studies [11]. It has high equilibrium water uptake of 0.404 g/g between 25C and 100C under 870Pa. The system specific cooling power (SCP) and coeffi...

This work presents a comparative study of microwave and conventional (conductive) heating for adsorbent regeneration. A binary gas mixture representative pre-dried flue from coal-fired power plants (15% v/v CO2 in N2) was passed through rotatory fixed-bed adsorption column filled with zeolite molecular sieve (13X) an activated carbon (Norit R2030CO2). The impact the two regeneration methods on ...

Infrared spectroscopy has been used in adsorption studies of trimethyl phosphite (TMP) on the hydrogen (H) form of the A-type and 13X zeolites. Infrared spectra of H-zeolites, except H-KA, show that TMP reacts rapidly with silanol hydroxyls on their surfaces and gives rise to form product molecules such as SiOCH3 and liquid dimethyl phosphite. The unaccomplished adsorption on the HKA zeolite ha...

Since deployment, our HPC environment has supported a 13x increase in compute demand, with a 10x increase in stability. In addition, tapeout time was reduced from 25 days for the first 65-nm process technologybased microprocessor in a non-HPC compute evironment to 10 days for the first 45-nm process technology-based microprocessor in an HPC-enabled envirnoment. The success of the HPC environmen...

Dne hundred and seventy five passerine birds from the Czech Republic were examined for the presence of sarcosporidia; auly 5 (all great tits) were positive for muscle cysts. Three great tits experimentally fed sporocysts (12.2 x 8.4, 11-13x 7.5-9 !lm) from a goshawk developed cysts while 2 house sparrows (Passer domesticus) were not infected. The cysts from great tits muscles were morphological...

The selective catalytic reduction (SCR) system in automobile using urea solution as a source of NH3 suffer from solid deposit problem pipe lines and poor efficiency during engine startup. Although direct use high pressure is restricted due to safety concern, which can be overcome by sorbents carrier. Strontium chloride (SrCl2) considered the best sorbent its sorption capacity; however, challeng...
