【摘要】 开发的Co-Mo-Al7719型催化剂具有酸性低、孔径大等特点,能在焦炉气气氛下长期运转。在1.5立升模试装置上单程运转2800小时,活性未见下降,催化剂上积炭只有5%。文中还讨论了催化剂的酸性及孔径对积炭的影响。更多还原

【Abstract】 A catalyst was developed for the hydrofining of raw naphthalene. It could run for 2800 hr in a 1.5L reactor of flowing system under 320—340℃, 40kg/cm², 0.8hr^-1 and gas/oil=500 by vol. with C deposit of only about 5% when using coke oven gas as hydrogen source.The effect of the acidity and the pore size of the catalyst on the coke formation was discussed.更多还原
