Distribution and Form of Iron and Calcium Compounds Before and After Residue Hydrogenation Under Different Space Velocities
文献摘要：
The distribution and form of iron and calcium compounds were studied using hydrogenation feedstock and hydrogenation products with different space velocities as the research object. The content of metallic elements, such as calcium and iron in hydrogenation feedstock, and extract samples were determined via flame atomic absorption spectrometry. The water-soluble iron and calcium species in oil samples were determined by an IC2010 high-throughput ion chromatograph. Nearly 60％–80％ of the iron or calcium compounds were mainly concentrated in resins and asphaltenes. Iron and calcium compounds mainly exist in the form of oil-soluble metal species in hydrogenation feedstock and hydrogenation products. Under certain conditions of reaction temperature, pressure, and volume ratio of hydrogen to oil, when the reaction space velocity was 0.6 h?1, about 30％ of the iron or calcium compounds were converted from oil-soluble to water-soluble species after hydrogenation. When the reaction space velocity was decreased from 1.70 to 0.60 h?1, the proportion of iron compounds converted from oil-soluble to water-soluble increased from 8.4％ to 28％. Moreover, the proportion of calcium compounds converted from oil-soluble to water-soluble increased from 10％ to 37％. This denotes that with decreasing reaction space velocity, the ratio of oil-soluble to water-soluble species increases. Water-soluble iron and calcium compounds are present in the form of inorganic salts, such as chlorate and sulfate. This study helps in understanding the removal mechanism of iron and calcium compounds and optimizing the operating conditions of residue hydrogenation.
