查询词典 methane

Even though,domestic increased rate of methane chlorides demanded is quicker than that of produced.

尽管如此，国内市场对甲烷氯化物产品的需求增长速度仍快于国内生产增长的速度。

Under the same condition as methane partial oxidation, the reaction results are as follows: CH4 conversions is 88%, CO selectivity is 90%, H2 selectivity is 68%, CO2 selectivity is 12%.H2-TPD indicates that it is difficult for H2 to desorb from catalyst. It is estimated that the reaction between hydrogen and oxygen being absorbed is the primary approach to produce H2O, and it maybe lead to the lower H2 selectivity.

反应结果如下：CH4转化率88%；CO选择性90%；H2选择性68%，CO2选择性12%。H2-TPD实验表明，H2在催化剂表面难于脱附，表面氢与表面氧反应可能是生成H2O的主要途径，这也可能是H2选择性比较低的原因。

The desorbed methane carbon isotope of coal core samples collected from Jincheng area, South Qinshui basin was measured.

对取自沁水盆地南部晋城地区的煤芯样中的解吸气进行了甲烷碳同位素测定。

During the displacement, the low adsorption methane was always first to be desorbed and the high adsorption CO2 was late to be desorbed. The displacement results under the high pressure is always better than the low pressure.

在置换过程中总是吸附能力弱的甲烷首先解吸，而吸附能力强的二氧化碳最后解吸，而且较高压力下的置换效果总比低压下的好。

The results indicate, the δ^13C1 value becomes heavier gradually as coalbed methane desorbs. The δ^13C1 value and the desorption time displays a logarithm relationship.

结果表明，随着解吸过程的进行，δ^13C1值逐渐变重，δ^13C1值和解吸时间呈对数关系，δ^13C1值变重趋势具有先快后慢的阶段性特点。

Methane production of the digesters can be further increased from 2.4 to 4.2 times.

反应器的甲烷产量可以藉由提高有机容积负荷增加2.4到4.2倍。

The government is trying to counter this by encouraging the spread of biogas digesters and larger-scale methane plants, but they have a long way to go.

政府正在鼓励推广生物饲料和沼气工程，但是还有很长的路要走。

The results showed no inhibitors in the anaerobic digestions of glucose, rice, vegetable and paper, the BMP of which were 241, 210, 147 and 244 mL·g-1 respectively, or 64.5%, 56.3%, 32.6% and 67.9% of the theoretical methane potential calculated by elemental analysis.

实验结果表明，葡萄糖、大米、蔬菜和纸张在发酵过程中没有消化抑制发生，4种原料的生化产甲烷能力分别为241、210、147和244mL·g-1，相应地占理论产甲烷能力的64.5%、56.3%、32.6%和67.9%。

For the two digestions of material proportion 83∶17 and 62∶38）with pH adjustment to 7.2 at the acidification stage, the stable pHs for methane production were 7.4~8.0, total VFA concentrations were 500~900 mg·L-1, propionic acid concentrations were 100~550 mg·L-1, and no ethanol production was detected.

实验结果表明，与单独利用食物垃圾以及未调节酸化阶段pH的厌氧消化相比，调节酸化阶段pH=7.2的食物垃圾与废纸联合厌氧消化能够避免挥发性脂肪酸抑制、保证消化稳定性并提高消化性能。

The reactions of transitional metal monoxides (TiO, ZrO, NbO, TaO, MnO, and FeO) and dioxides (VO_2, NbO_2, and TaO_2) with methane were investigated by matrix isolation infrared spectroscopic and quantum chemical calculations.

在本论文中我们利用低温基质隔离红外光谱方法研究了一些过渡金属一氧化物(TiO，ZrO，NbO，TaO，MnO和FeO)以及二氧化物(VO_2，NbO_2和TaO_2)与甲烷的反应。
