The lactate to sulfate molar ratio in reactor R2a (1.94 mol mol−1) was increased by a factor of three compared to the inoculum, reactor R-0 (0.67 mol mol−1) and a factor of about six compared to reactor R1 (0.34 mol mol−1).
In the first series, as the concentration of the SPS ionomer component (2.65 mol%) was increased, the average fatigue lifetimes were reduced with an apparent minimum at 30 wt%.
The production per mol photons was increased 40-50% by 30% shading.
The mesophase transformation from cubic Im¯3m to Ia3d symmetries occurred when the concentration of cerium nitrate was increased from 0 1 mol% to 5 8 mol%; while higher ceria loadings resulted in the formation of phase segregated alumina-rich spheres embedded in a ceria-rich matrix.
However, the yield and concentration of hydrogen were kept at similar levels with the increase of Ca. By normalizing the yield of hydrogen in relation to the amount of Ni presented inside the catalyst, the hydrogen yield per mole of nickel was increased from 50 g Ni −1 0.1Ca catalyst) to 80 g Ni−1 (0.8catalystyst) when the Ca addition was increased from 10 mol% to 80moll%.
CO conversion was increased from 9.1 mol% at T = 200 °C and H2/CO = 1 to 79.6 mol% at T = 240 °C and H2/CO = 2 and the yield and selectivity of DME also increased from 7.11% to 47.05% and 41.57% to 59.96%, (molar basis) respectively.
From a phase behavior study of these hybrid materials using a differential scanning calorimeter (DSC) and solid-state nuclear magnetic resonance (NMR) spectroscopy, it was found that the hybrid system was miscible for organic and inorganic phases with low silane content, but exhibited heterogeneously when silane content was increased to 40 mol% or more.
In view of the lower intrinsic reactivity of 4 a, its concentration was increased to 3 mol % in toluene, and at 0 °C this gave a good conversion to 6 a with 83 % ee (entry 13).
However, when the solvent in the second step was changed to CH2Cl2 and the amount of (S)- 5 was increased to 20 mol %, the entire process could be conducted at 0 °C to give the aryl addition products with high enantioselectivity (88 96% ee) for the aromatic, aliphatic, and α,β-unsaturated aldehydes (Table 7).
They also observed that as the hydrocarbon mol ratio was increasing with a corresponding decrease in aromatic carbon content, the yields of dry gas, diesel oil was decreasing, but the coke yield showed an increasing trend.
