Abstract: According to the technical characteristics of STRONG ebullated bed hydrogenation process, the microspherical catalysts for ebullated bed residue and coal tar hydrogenation were developed. The microspherical residue hydrogenation catalysts were used successfully in 50,000 TPY ebullated bed residue hydrogenation demonstration unit, showing good reaction performance and wear resistance, which was comparable to the advanced technology abroad. The microspherical coal tar hydrogenation catalyst with good hydrolytic resistance and hydrogenation performance has been applied in 0.5 MM TPY coal tar ebullated bed hydrogenation unit of Shaanxi Jingyi Chemical Co.,Ltd. In view of the introduced ebullated bed hydrogenation unit, the strip type coal liquefaction oil and residue hydrogenation catalysts were developed. The coal liquefaction oil hydrogenation catalyst has been successfully applied in the hydrogenation stability unit of Shenhua Ordos Coal to Oil Company. With good aromatic hydrogenation selectivity and high wear resistance, the overall performance of the catalyst was better than that of foreign technologies. Due to its high lateral compressive strength and wear resistance, the hydrogenation performance of the strip type ebullated bed residue hydrogenation catalyst was on par with the advanced technology abroad.
