Results of hydrotreating the kerosene fraction of HTI`S first proof of concept run

PDF Version Also Available for Download.

Description

The objective of Sandia`s hydrotreating study is to determine the relationships between hydrotreating conditions and product characteristics for coal liquids produced using current technologies. The coal-derived liquid used in the current work is the kerosene fraction of the product from Hydrocarbon Technologies Inc.`s first proof-of-concept run for it`s Catalytic Two-Stage Liquefaction Technology. Sandia`s hydrotreating experiments were performed in a continuous operation, microflow reactor system using aged HDN-60 catalyst. A factorial experimental design with three variables (temperature, pressure, liquid hourly space velocity) was used in this work. Nitrogen and sulfur contents of the feed and hydrotreated products were determined using an ... continued below

The coal-derived liquid used in the current work is the kerosene fraction of the product from Hydrocarbon Technologies Inc.`s first proof-of-concept run for it`s Catalytic Two-Stage Liquefaction Technology. Sandia`s hydrotreating experiments were performed in a continuous operation, microflow reactor system using aged HDN-60 catalyst. A factorial experimental design with three variables (temperature, pressure, liquid hourly space velocity) was used in this work. Nitrogen and sulfur contents of the feed and hydrotreated products were determined using an Antek 7000 Sulfur and Nitrogen Analyzer. Multiple samples were collected at each set of reaction conditions to ensure that each condition was lined out. Hydrotreating at each set of reaction conditions was repeated so that results could be normalized for catalyst deactivation. The normalized results were statistically analyzed. Increases in temperature and pressure had the greatest effects on nitrogen removal. The highest severity condition (388{degrees}C, 1500 psig H{sub 2}, 1.5g/h/g(cat)) gave a measured nitrogen value of <5 ppm.
