ClearPlus™ Series Centaur Catalytic Carbon Filter systems are designed to backwash periodically to eject trapped sediment and particulates and to prevent channeling that could reduce system performance. Accordingly, the control valve is connected to a drain, and the backwash water (together with the ...
The evaluation of catalytic activity, reaction mechanism and catalyst classification in diesel particulate filter: a reviewdoi:10.1007/s10098-024-02819-wDiesel particulate filterReaction mechanismCatalyst typeCatalytic soot oxidationDiesel engines are widely used because of their high power, and diesel ...
The invention discloses a faint scent active carbon filter material with a strong catalytic degradation effect. The filter material is prepared by using the following raw materials, by weight, 137-147 parts of active carbon, 9-13 parts of nanometer titanium dioxide, 3-4 parts of acrylic acid,...
5 filter paper. The sample is uniformly spread across the filter paper, and water is evenly sprayed. The specimens were permitted to drain freely until the last drop had emptied, and then the funnel was sealed from the top to reduce evaporation loss. The water holding capacity was determined...
a week. Then the C-dots solution was condensed and ultra-filtered by using a Millipore centrifuge filter device with a molecular-weight cut-off (MWCO) membrane of 100 kDa. The separated fraction with weight equivalent to <100 kDa was collected and stored for use. It is noted that the...
Before RapidFire analysis, the reaction was quenched by an equal volume of ACN at various times (0.5–30 min) and the quenched solution was centrifuged at 12,000g for 10 min and filtered by a 0.22-μm nylon membrane syringe filter (FilterBio Nylon Syringe Filter) to obtain the filtrate ...
Qualified grids were transferred to a Titan Krios microscope (FEI) operated at 300 kV for data acquisition and equipped with Gatan K2 Summit detector and GIF Quantum energy filter. Images were automatically recorded using AutoEMation with a slit width of 20 eV for the energy filter and in...
The aim of this paper is to review the catalytic reactions for the removal of NO and, more particularly, to discuss the reduction of NO in the presence of NH3, CO, H2 or hydrocarbons as well as the decomposition of NO. The nature of the different active species, their formation due to...
After filtering the clarified cell lysate through a 0.45 μm filter, the crude protein solution was loaded onto the column at a flow rate of 3 ml min−1. The disulfide bond between PtGSTF8 residue C13 and GSH was reduced on-column with 20 column volumes of rPPS buffer (20...
Imidazole was reduced to 10 mM in an Amicon 10-kDa centrifugal filter. The tag was removed by 3 C protease cleavage overnight and capture on Ni-NTA resin. Protein was subsequently loaded onto were a Superdex 75 column equilibrated concentrated to 16 mg/mL. in 50 mM HEPES pH 7.5...
