【摘要】 以镁铝尖晶石复合材料为载体,采用浸渍钴钼活性组分无煅烧技术,中试制备出新型XH-1无钾耐硫变换催化剂。对该催化剂进行实验室活性评价和6个月的工业侧线试验,结果表明:XH-1型催化剂结构稳定、机械强度高;在中压(2.0MPa)、低汽气比(0.3~0.6)的反应条件下,催化活性优于国内外同类产品;在高压(≥3.0 MPa)、高汽气比(≥1.0)条件下催化性能与同类产品相当,符合高、中压各种变换工艺条件对催化剂性能的要求。更多还原

【Abstract】 New XH-1 type of potassium-free sulfur-tolerant water gas shift catalyst was trial produced on a pilot scale by the impregnation of Co-Mo active composition on the complex support of magnalium-alumina spinel without calcination.The results of both the evaluation in the laboratory and the industrial sidetrack test in a period of six months showed that the XH-1 type of catalyst had higher activity in comparison with the same type of products made in inland and overseas under medium pressure(2.0 MPa) and at low steam-to-gas ratio(0.3-0.6),but the same activity under high pressure(≥3.0 MPa) and at high steam-to-gas ratio(≥1.0).Moreover the XH-1 type of catalyst was found to have stable construction and high mechanical strength.The catalyst was suitable for different shift technology conditions of high and medium pressure.更多还原
