The Effect of 1-Butanol Co-Feeding on Propylene Production in the MTP Reaction
The propylene production with 1-butanol co-feeding for methanol in relation to propylene process (MTP) at 440-490 ̊C temperature range and at 0.9-15 hr-1 WHSV range over H-ZSM-5 zeolite catalyst is assessed in a isothermal fixed-bed reactor. The feedings here are of: pure 1-butanol, pure methanol and a 1-butanol and methanol mixture. The effect of 1-butanol co-feeding on selectivity of propylene...
متن کاملAqueous-sensitive reaction sites in sulfonic acid-functionalized mesoporous silicas
Local differences in surface hydrophilicities/hydrophobicities of propyland arene-sulfonic-acid modified mesoporous silica and organosilica catalysts have been compared and correlated with their bulk catalytic properties for aqueous-sensitive organic reactions. Syntheses of propyland arene-SO3H-modified mesoporous silicas and organosilicas yield materials with different hydrophilicities, especi...
متن کاملRoles for the two 1-butanol dehydrogenases of Pseudomonas butanovora in butane and 1-butanol metabolism.
Pseudomonas butanovora grown on butane or 1-butanol expresses two 1-butanol dehydrogenases, a quinoprotein (BOH) and a quinohemoprotein (BDH). BOH exhibited high affinity towards 1-butanol (K(m) = 1.7 +/- 0.2 microM). BOH also oxidized butyraldehyde and 2-butanol (K(m) = 369 +/- 85 microM and K(m) = 662 +/- 98 microM, respectively). The mRNA induction profiles of BOH and BDH at three different ...
متن کاملBiotrickling Filtration of Air Contaminated with 1-Butanol
The removal of high concentrations of 1-butanol in an air stream was evaluated with a biotrickling filter for potential application to an industrial off-gas. Experiments were conducted on a laboratory-scale system, packed with perlite, in a co-current downward mode with constant recycling of water. The performance was monitored for different inlet concentrations and empty bed residence times du...
متن کاملComparison of adsorptions of phenol,p-nitrophenol and 1-butanol on the activated carbon
Adsorption of 1-Butanol, Phenol, and P-nitrophenol on activated carbon havebeen studied. The results were used to testifying the validity of different modelsbased on thermodynamic principles: Freundlich, Langmuir and Henry isotherms.The maximum capacity of adsorbent for three compounds was determined, Theconstants of equilibrium were determined by Freundlich isotherm and virialisotherm expressi...
