Dehidrasi Etanol Menggunakan Zeolit Teraktivasi Irradiasi Lampu Sinar Ultraviolet (UV Light) pada Kolom Fixed Bed

نویسندگان

چکیده

Untuk mendapatkan kemurnian etanol >99,5% diperlukan metode adsorpsi menggunakan Zeolit Alam Lampung (ZAL). Agar dapat digunakan sebagai adsorben zeolit harus dilakukan aktivasi dengan irradiasi lampu sinar ultraviolet germicidal lamp 254 nm, black light 360 nm dan insect 546 nm. Hasil uji karakteristik BET didapatkan luas permukaan non-treatment 41,331 m2/g, 41,158 40,399 m2/g 38,796 m2/g. Total volume pori terbesar didapat dari uv 0,0690 cc/gram ukuran rata-rata terdapat pada akivasi 35,57 Å. Setelah diaktivasi dibentuk pellet binder tepung terigu komposisi 35% berat zeolit, kemudian di kalsinasi untuk menghilangkan yang masih merekat membuka tertutup binder. diperoleh dehidrasi meningkatkan teraktivasi 98,69% v/v selama 45 menit, 55 menit.

Ultraviolet (UV) light perception by birds: a review

The ability to perceive the near ultraviolet part of the light spectrum (the wavelength 320–400 nm) has been detected in many bird species. This ability is an important bird sense. The ecological importance of UV perception has been studied mainly in the context of intraand inter-sexual signalling, common species communication and also in foraging. Some birds of prey use UV reflectance in their...

Formation of Zinc Aluminium Layered Double Hydroxides -4(2,4-dichlorophenoxy)butyrate Nanocompisites by Direct and Indirect Methods

4-(2,4-dichlorophenoxy)butyric acid (DPBA) was intercalated between the interlamellae of Zn/Al layered double hydroxides (LDHs). Two methods of intercalation were adopted, (a) direct synthesis by co-precipitation of metal nitrates and DPBA and (b) ion exchange of LDH nitrate with the organic anion. The resulting materials were characterized by x-ray diffraction and infrared spectroscopy. Both m...
