Fig. 3 shows the emulsion phased expansion measured by the bed collapse method [10] under the reaction conditions. In this case, the value of α was 3.9. The expansion ratio when the bed was fluidized by only H2 shows that the emulsion phase slightly expanded, and that the ratio was not...
aFor practical reasons, leaching studies are performed on a homogenized sample, testing the temperature dependency of the rate of reaction (concentration and time) in various leaching mixtures. 为实用原因,浸出研究在一个均匀的样品执行,测试反应的率的温度附庸(集中和时间)以各种各样的浸出的混合物。 [...

The urea hydrolysis reaction rate, R, was assumed to be constant within the entire biofilm in each tube (independent of concentration) and constrained to the biofilm domain (no reaction in the liquid phase). Justification for the constant reaction rate assumption follows in section 'Reactive ...
In the fields of occupational medicine and occupational health science, the HR during work Footnote 3 (HRwork) is taken into consideration while analysing the respective activity, e.g., evaluation of physical work. The HRwork is defined as the difference between HRrest and the value measured durin...
The great utility of the effectiveness factor concept to account for intraparticle diffusion lies in its simplicity of application. Unfortunately, the standard formulation leads to a separate relationship for each type of reaction rate form, which greatly complicates practical computations. A general asy...
Comprehensive research results show that the fouling rate is mainly affected by mass transfer at low flow rate while it is mainly affected by surface reaction rate at high flow rate[47,48]. Ahfir et al.[49]explored the transport and deposition rates of suspended particles in saturated porous ...
The logistic function is derived from a type of reaction equation in which both the beginning and ending state weigh in, i.e. (in simplified form),(18)∂ψβ∂β=Hψβ1−ψβνwhere H is a coefficient describing the rate of change with respect to the independent variable (i.e.,...
