| Abstract: | The physical parameters and hydrofining reaction mechanisms of hydrofining catalyst LYT-701 are described.The control of temperature rise of catalyst in pre-sulfiding and hydrogenation beds in hydrogen generation from coker off-gas is detailed.The results show that,the hydrofining catalyst LYT-701,when applied in combination with zinc oxide desulfurization catalyst,can reduce the olefin in high-olefin and high-sulfur coker off-gas by minimum 1%(v),and the total sulfur could be lowered to 0.5 mg/m~3,meeting ... |
