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.

           戊烷產(chǎn)品是異戊烯生產(chǎn)裝置中分離出來(lái)的醚后戊烷經(jīng)過(guò)加氫所得,鈷鉬催化劑;催化劑需要在氫氣環(huán)境下用固體硫活化,通過(guò)檢測(cè)活化過(guò)程中H2S的含量來(lái)考察催化劑活化程度,H2S的濃度控制在1.0%左右,因而準(zhǔn)確地測(cè)定硫化氫含量就可以準(zhǔn)確的知道催化劑的活化程度。

         滕州市翔鷹分析技術(shù)有限公司采用GC7990毛細(xì)管氣相色譜法,(30m×0.32mm i.d.×40μm)色譜柱,熱導(dǎo)檢測(cè)器,氫氣為載氣,氮?dú)獯媪蚧瘹錁?biāo)準(zhǔn)氣體的外標(biāo)法測(cè)定硫化氫含量。精密度RDS為0.6%,平均回收率為97%;考察了取樣袋施加不同壓力對(duì)測(cè)定結(jié)果的影響,壓力與測(cè)定面積的線性方程y=121x+202,相關(guān)系數(shù)r=0.997;分流比在2.5:1~20:1范圍時(shí),濃度范圍0.25~2.00%,分流比倒數(shù)與面積線性方程y=873x+39.3,相關(guān)系數(shù)r=0.999,硫化氫峰面積與其濃度有良好的線性關(guān)系;zui低檢測(cè)線為50ppm;該方法可以準(zhǔn)確測(cè)定氫氣中硫化氫的含量。
