[交流] 求译一段话

以等体积浸渍法制备了摩尔比为10,3,1,1/3,1/10,负载量为5%,10%,15%,20%,25%,30%的M-F/Al2O3颗粒。典型合成过程如下:首先取一定量的Al2O3在500度煅烧4小时后筛分至20-40目留用。Al2O3参数列于表一。根据已计算的Mn、Fe摩尔比及负载量,称取定量Fe(NO3)3及Mn(NO3)2溶于去离子水中,搅拌至均匀。将混合溶液以气雾形式喷入瞬时搅拌的Al2O3颗粒中,密封老化24h,而后转入110℃下恒温干燥箱干燥2h,接着以1℃/min的速率程序升温至500℃焙烧4h,最后退火冷却至室温。另外,考虑到浸渍过程酸碱中和方式的影响,实验过程还分别添加了四甲基氢氧化铵(0.0135mol)及氨水(0.0135mol)进行比较。

Prepared by impregnation with an equal volume of the molar ratio of 10,3,1,1 / 3,1 / 10, the load capacity of 5%, 10%, 15%, 20%, 25%, 30% of the MF/Al2O3 particles. A typical synthesis process is as follows: First, take a certain amount of Al2O3 calcined at 500 degrees for 4 hours, sieving to 20-40 mesh retained. Al2O3 parameters listed in Table 1. Has been calculated according to the Mn, Fe molar ratio and load, that take quantitative Fe (NO3) 3 and Mn (NO3) 2 dissolved in deionized water, stirring to evenly. The mixed solution in the form of aerosol spray into the instantaneous mixing of the Al2O3 particles, sealing aging 24h, then transferred to drying oven at 110 ℃ temperature 2h, followed by 1 ℃ / min rate of temperature programmed to 500 ℃ calcined 4h, the final annealing cooled to room temperature. In addition, taking into account the pH in the impregnation process and methods of the experimental process also were added to 4-methyl ammonium hydroxide (0.0135mol) and ammonia (0.0135mol) were compared. .

by impregnation with an equal volume, incipient wetness impregnation
4-methyl ammonium hydroxide , tetramethylammonium hydroxide
其他的不想看了
楼主还是找相应的英文文献对着译好些。

或者谁对照中文帮忙修正一下~~

The  particles with Mn/Fe molar ratios of 10, 3, 1, 1/3, 1/10 and different loading were prepared by incipient wetness impregnation [17]. A typical synthetic procedure was as follows: firstly took a certain amount of  Al2o3 calcined at 500C for 4 hours, then retained them as support (20-40 mute). Properties of Al2o3   are listed in Table 1. According to the calculated molar ratio and loading, took quantitative  Fe (NO3) 3  and Mn(NO3)2  into solution by adding deionized water. Further, sprayed the mixed solution into  particles (5g) and instantaneous stirred at the same time. sealed and aged for 24 hours in the air, and then transferred them to thermostatic drying oven dried for 2h at 110C, followed by 1 C/min rate temperature-programmed to 500C and calcinated for 4h, the final cooled to ambient temperature. Besides, considered partially alkali neutralization, 0.0135mol tetramethy-lammonium hydroxide (25%, AR, Sinopharm Chemical Reagent Co., Ltd) and 0.0135mol aqueous ammonia ( AR, Sinopharm Chemical Reagent Co., Ltd) are used in the process of impregnation. Definitions of the above samples are shown in Table 2.


帮忙润化一下~~~

Mn/Fe particles with molar ratios between Mn and Fe of 10, 3, 1, 1/3, 1/10 and different loadings from 5% to 30% with a step of 5% were prepared using incipient wetness impregnation method[17]. The typical synthetic procedure was as follows: a certain amount of Al2O3 particles was first calcined at 500C for 4 hours and was then sifted to 20-40 mesh in size for further processing. Properties of Al2O3 are listed in Table 1. According to the designed molar ratios and loadings, certain amounts of Fe(NO3)3 and Mn(NO3)2 were uniformly  mixed with deionized water. The mixed solution was then vaporously sprayed into Al2O3 particles (5g) which were simultaneously stirred for uniformity. This mixture was sealed and aged for 24 hours in the air, and then was transferred into a thermostatic drying oven and was kept drying at 110C for 2 hours. After all these steps, the temperature of the mixture was raised at a rate of 1C/min to 500 C and annealed at this temperature for 4 hours, and then cooled down to the room temperature. Because of considering the possible effect of the partially alkali (-acidic) neutralization, 0.0135mol tetramethy-lammonium hydroxide (25%, AR, Sinopharm Chemical Reagent Co., Ltd) and 0.0135mol aqueous ammonia ( AR, Sinopharm Chemical Reagent Co., Ltd) were, respectively, employed in the sample preparation for comparison. Definitions of the above samples are shown in Table 2.

润色了一下:
The Mn-Fe/Al2O3 catalysts with the molar ratio of Mn/Fe equaled to 10, 3, 1, 1/3, 1/10, 1/10( ??,对应于30 wt.%) and a composition of 5, 10, 15,20, 25, 30 wt.% Mn and Fe in Al2O3 respectively were prepared by incipient wetness impregnation method[17]. In a typical synthesis, the Al2O3 sample was first calcined at 500 ℃ for 4 hours and then sifted to 20-40 mesh for further use. Properties of Al2O3 are listed in Table 1. According to the designed molar ratios and loadings, certain amounts of Fe(NO3)3 and Mn(NO3)2 were dissolved in deionized water under stirring. The homogenous solution was then vaporously sprayed onto Al2O3 particles (5g) under simultaneously stirring for uniformity. The mixture was sealed and aged for 24 hours, and then was transferred into a drying oven at 110℃ for 2 hours. The mixture was heated up to 500℃ at a rate of 1℃/min, this temperature was maintained for 4 h. Furthermore, to study the effect of impregnation solution acidity, 0.0135mol tetramethyl ammonium hydroxide (25%, AR, Sinopharm Chemical Reagent Co., Ltd) and 0.0135mol aqueous ammonia (浓度, AR, Sinopharm Chemical Reagent Co., Ltd) were also added in the impregnation solution, respectively. Definitions of all the catalysts are shown in Table 2.
