Abstract

The hydrofining of semicoking coal tar from the Shubarkul deposit (Republic of Kazakhstan) in the presence of nanoheterogeneous molybdenum sulfide catalyst systems (Mo content, 0.025–0.12%) was studied in order to intensify processing technology. The catalysts were in situ prepared in the coal tar with the addition of a sulfidizing agent—elemental sulfur in an amount of 0.03 –0.09 wt % on a raw material basis. It was found that the effective Mo content of the catalyst was 0.025%, and the amount of sulfur was 0.03%, which made it possible to obtain a maximum yield of total liquid products (76.8%), which mainly contained diesel fuel fractions, at 5 MPa and 400°C.

纳米非均相硫化钼催化剂在舒巴库尔矿床煤半焦焦油加氢精制中的应用

摘要

为了增强加工技术，研究了在纳米均相硫化钼催化剂体系（Mo含量为0.025-0.12％）存在下，从Shubarkul矿床（哈萨克斯坦共和国）对半焦煤焦油进行加氢精制。催化剂是在煤焦油中原位制备的，其中添加了以原料为基准的0.03-0.09 wt％的硫化剂-元素硫。发现催化剂的有效Mo含量为0.025％，硫的含量为0.03％，这使得有可能获得最大液体总产物（76.8％）的最大产率，该液体产物主要包含柴油燃料馏分。 5 MPa和400°C。
