N-Methylation of amines with cO_(2) and H2 is a potential approach for cO_(2) utilization because N-methylated amines can be used as solvents and organic intermediates. In_(2)O_(3)-supported cu (cu/In_(2)O_(3)) acts as an effective heterogeneous catalyst for N-methylation reaction of N-methylaniline (MA) with cO_(2) and H_(2),showing higher N,N-dimethylaniline (DMA) selectivity than other supported cu catalysts. On one hand,the dispersion of cu can be improved by the defective In_(2)O_(3) support. On the other hand,In_(2)O_(3) support is active in the dissociative adsorption of cO_(2) through c—O bond breaking. In addition,the H_(2) dissociation ability of In_(2)O_(3) can also be enhanced by cu. The combination of cu and In_(2)O_(3) is effective in the activation of cO_(2),the adsorption of intermediate N-methylformanilide (MFA),the hydrogenation of MFA to DMA and the prohibition of c—N bond cleavage side reactions,thereby enhancing the reaction rate of MA conversion and the selectivity to DMA.

The melting process of solid-liquid phase change materials(PcM)has a significant impact on their energy storage *** more effectively apply solid-liquid PcM for energy storage,it is crucial to study the regulation of melting process of solid-liquid PcM,which is numerically investigated based on double multiple relaxation time lattice Boltzmann method(MRT-LBM)in this *** this work we pay more attention to the effects of different Stefan numbers(Ste)and Rayleigh numbers(Ra)on the melting *** results indicate that the PcM melting is greatly influenced by the Ste number and Ra number,which can be divided into the heat conduction dominant stage and the convection dominant stage,according to the onset time of convection Fo_(c).In order to describe the contribution of the heat conduction dominant stage to the whole melting process quantitatively,we firstly propose the ratio of the heat conduction dominant stage R_(pc),which can be defined as the ratio of Fo_(c)to the complete melting time Fo_(M).R_(pc)gradually decreases as the Ra number increases,and when the Ste number rises:R_(pc)=90.0%when Ste=1.0 and Ra=1×10^(5),R_(pc)=39.6%when Ste=0.1 and Ra=1×10^(5),and R_(pc)=14.0%when Ste=1.0 and Ra=1×10~7.A regime map about the effects of different Ste numbers and Ra numbers on R_(pc)has been further *** discovered findings would be helpful in regulating melting process in the energy storage of solid-liquid PcM.
