查询词典 carbon monoxide

From the point view of product distribution, conversion of dimethyl ether and energy consumption, with RCD plasma DME conversion was higher and was hardly affected by the residence time of dimethyl ether, and hydrogen, carbon monoxide and unsaturated hydrocarbons with RCD plasma were more than those with DBD plasma.There was no liquid product with RCD plasma, but the liquid product obtained with DBD plasma consisted of aldehydes, alcohols and methoxy-containing organic compounds, for instance, formaldehyde, methyl alcohol, dimethoxy ethane and so on.Moreover, most compositions of liquid product were methoxy-containing compounds, and the liquid product selectivity was as high as 32.23%.However, energy consumption for the reaction with DBD plasma was more than that with RCD plasma.

Results Compared with CRF group, nephrogenic hypertension of hemin group was reduced significantly at the 6th, 8th, 10th week after operation, and followed with the decrease of serum creatinine, BUN,urinary protein and the improvement of nephrogenic anemia at the 10th week after operation. Hemin not only increased the expression of HO-1, reduced the expression of ET-1 in the kidney, but also increased the concentration of carbon monoxide, reduced the level of ET-1 in the plasm.
