Catalytic and Non-catalytic Conversion of Methane to C2 Hydrocarbons in a Low Temperature Plasma
The direct conversion of methane to C2 hydrocarbons, in a quartz tube reactor enforced by a DC corona discharge, was investigated at atmospheric pressure. The process was carried out in the presence of metal oxide catalysts of Mn/W/SiO2, Mn/W/SiO2 (tetraethyl orthosilicate, TEOS), and Mn/W/CNT (supported on carbon nanotubes). The total yield to C2 hydrocarbons in the presence of metal oxide cat...
متن کاملThe N-acetylhexosaminidase components of the ram testis and epididymis.
Three and four N-acetylhexosaminidase components, from ram testis and epididymis respectively, have been separated by ion-exchange chromatography on DEAE-cellulose. Although they all have the same molecular weight (approx. 140000) and very similar catalytic properties towards the synthetic substrates, 4-methylumbelliferyl N-acetyl-beta-glucosaminide and N-acetyl-beta-galactosaminide, isoelectri...
متن کاملPurification and Characterization of β-N-Acetylhexosaminidase from Rice Seeds
N-Acetyl-β-D-hexosaminidase (β-HexNAc’ase) (EC 3.2.1.52) was purified from rice seeds (Oryza sativa L. var. Dongjin) using ammonium sulfate (80%) precipitation, Sephadex G150, CM-Sephadex, and DEAE-Sephadex chromatography, sequentially. The activities were separated into 7 fractions (F1F7) by CM-Sephadex chromatography. Among them, F6 was further purified to homogeneity with a 13.0% yield and 1...
متن کاملAssay of serum/plasma beta-N-acetylhexosaminidase isoenzymes by heat inactivation using a continuous spectrophotometric method adapted to a centrifugal analyzer.
Activity of serum/plasma beta-N-acetylhexosaminidase (EC 3.2.1.52) was determined by means of a continuous spectrophotometric method using 3,3'-dichlorophenylsulphonphthaleinyl-N-acetyl-beta-D-glucosaminid e as substrate, with very satisfactory results. Incubation of an undiluted aliquot (1 ml) of samples at 52 degrees C for 8 hours with an adjusted pH 5.5-6.0 provoked only the inactivation of ...
