Preparation of MFI type zeolite membranes in a flow system with circulation of the synthesis solution
Çulfaz Emecen, Pınar Zeynep; Kalıpçılar, Halil (2006-06-20)
MFI type zeolite membranes were prepared on seeded tubular alumina supports in a flow system where the synthesis solution was circulated through the support with flow rates of 6, 24 and 48 mL/min. Syntheses were carried out using clear solutions, at 80 degrees C and 95 degrees C at atmospheric pressure in the flow system, and at autogeneous pressure in the batch system. The membranes synthesized in the flow system had thickness of 1-2 mu m, and were thinner than the membranes synthesized in the batch system...
Preparation of B-ZSM-5 membranes on a monolith support
Kalıpçılar, Halil; Noble, RD (2001-11-30)
A B-ZSM-5 zeolite membrane was synthesized on a monolith support containing 60 channels (2 mm x 2 mm.). The membrane showed a n-C4H10/i-C4H10 ideal selectivity at 373 K of 79 and a separation selectivity of 30.
Synthesis and separation properties of B-ZSM-5 zeolite membranes on monolith supports
Kalıpçılar, Halil; Noble, RD; Falconer, JL (2002-12-01)
Alumina-coated, silicon carbide monoliths were used as supports for B-ZSM-5 zeolite membranes, which were synthesized by in situ hydrothermal crystallization. Both 2 turn x 2 mm (66 channels) and 4 mm x 4 mm (22 channels) monoliths with effective membrane area/volume ratios of 10.6 and 7.2 cm(2)/cm(3), respectively, were used. The membranes separated C-4 and C-6 hydrocarbon isomer vapor mixtures with high selectivities. The selectivities and permeances were comparable to tubular ZSM-5 membranes for butane i...
Separation of silkworm proteins in cocoon cooking wastewaters via nanofiltration: Effect of solution pH on enrichment of sericin
ÇAPAR, GÖKŞEN (2012-02-01)
Cocoon cooking wastewater contains waste silkworm proteins including sericin, which is a valuable raw material for many industries including cosmetics and pharmaceuticals. Sericin can be recovered via nanofiltration (NF) with high efficiency; however the process conditions need to be optimized to maximize separation. In this study, the effect of solution pH on NF performance was investigated for separation of silkworm proteins towards sericin enrichment. Solution pH (3.5-9.0) slightly influenced sericin rej...
Separation of sericin from fatty acids towards its recovery from silk degumming wastewaters
Capar, Goksen; Aygun, S. Seylan; Gecit, M. Rusen (Elsevier BV, 2009-10-15)
Sericin is a valuable protein, which is currently discarded as a waste in silk industry. Silk degumming wastewaters (SDW) are abundant sources of sericin, however, they contain impurities such as salts of fatty acids (soap) in conventional degumming processes. In this study, a process consisting of centrifugation (CFG), low temperature crystallization (LTC) and ultrafiltration (UF) was developed to separate sericin from fatty acids towards its recovery from conventional SDW. Complete removal of fatty acids ...
