Sentence examples for conversion with time from inspiring English sources
The nucleation and nuclei growth model with chemical reaction control properly described the evolution of solids conversion with time.
The extent of solid conversion with time could not be predicted by the classical correlations obtained by assuming a single rate limiting step.
A qualitative interpretation of the transformation is proposed, as well as a geometrical modeling that leads to the variations of the fractional conversion with time.
AlCl3 on γ-Al2O3 support having macro- and meso-pore bimodal structure show excellent catalytic activity and high stability, while those on γ-Al2O3 with micro (d 15.6 Å) and meso-pore (d 28.6 Å) structure exhibit low stability and rapid fall of conversion with time.
Open image in new window Fig. 2 Variation of carbon conversion with time at different gas flow rate in a raw coke samples and b samples adsorbed Na2CO3.
Open image in new window Fig. 3 Variation of carbon conversion with time at different particle size in a raw coke samples and b samples adsorbed Na2CO3.
Low-conversion catalytic tests performed at constant temperature showed that on well-dispersed Pt/Al2O3 catalysts the cyclopentane conversion increases with time on stream, while the methane activity decreases.
The residence time distribution (RTD) of solids is essential for the design of CFB reactors where conversion proceeds with time.
The Central Logic Board (CLB) has been developed to acquire timing and amplitude information from the PMT signals, implementing time-to-digital conversion (TDC) with time over threshold (TOT) technique.
Reliable estimates of catalyst deactivation parameters are difficult to get from conventional experiments at constant space velocity where conversion declines with time on stream, or when temperature is adjusted to compensate for the loss of catalyst activity.
The acidity of the HZSM-5 zeolite also has an influence on the nature of the coke, given that it contributes to increasing coke condensation towards polycondensed aromatic structures, although this has a minor effect on bio-oil conversion decrease with time on stream.
