Pentane product is isoamyl olefine production device in the ether of pentane after a hydrogenation, cobalt, molybdenum catalyst; Catalysts in the hydrogen environment necessary to use solid sulfur activation, by detecting the content of H2S in the activation process to examine the catalyst activation degree, at about 1.0%, the concentration of H2S control and accuray determine hydrogen sulphide can accuray know the activation of catalyst.

xiang ying eagle analysis technology co., LTD. By GC7990 capillary gas chromatography, I.D. (30 m x 0.32 mm x 40 microns) chromatographic column, the thermal conductivity detector, hydrogen as carrier gas, nitrogen gas instead of hydrogen sulphide standard external standard method of determination of hydrogen sulphide. Precision of RDS is 0.6%, the average recovery was 97%; Inspected the sample bags of different pressure on the determination results, the influence of pressure and determine the size of the linear equation y = 121 x + 202, the correlation coefficient r = 0.997; Split ratio in 2.5:1 ~ those days of scope, concentration range of 0.25 ~ 2.00%, split ratio and bottom area of linear equation y = 873 + 39.3 x, correlation coefficient r = 0.999, h2s has a good linear relationship between peak area and concentration; Lines of a minimum of 50 PPM. The method can accuray determine the content of hydrogen in the hydrogen sulfide.

           戊烷产品是异戊烯生产装置中分离出来的醚后戊烷经过加氢所得,钴钼催化剂;催化剂需要在氢气环境下用固体硫活化,通过检测活化过程中H2S的含量来考察催化剂活化程度,H2S的浓度控制在1.0%左右,因而准确地测定硫化氢含量就可以准确的知道催化剂的活化程度。

         滕州市翔鹰分析技术有限公司采用GC7990毛细管气相色谱法,(30m×0.32mm i.d.×40μm)色谱柱,热导检测器,氢气为载气,氮气代替硫化氢标准气体的外标法测定硫化氢含量。精密度RDS为0.6%,平均回收率为97%;考察了取样袋施加不同压力对测定结果的影响,压力与测定面积的线性方程y=121x+202,相关系数r=0.997;分流比在2.5:1~20:1范围时,浓度范围0.25~2.00%,分流比倒数与面积线性方程y=873x+39.3,相关系数r=0.999,硫化氢峰面积与其浓度有良好的线性关系;zui低检测线为50ppm;该方法可以准确测定氢气中硫化氢的含量。
