    TK-719

    TK-719 is a high-porosity demetallization catalyst for fixed-bed resid service. It is applied in the front-end of resid hydrotreaters due to its enhanced ability to remove metals and asphaltenes and to reduce Conradson carbon residue (CCR). Even though large particles usually result in lower...

    TK-733

    TK-733 is a demetallization (HDM) catalyst with moderate hydrodesulfurization (HDS) activity for fixed-bed resid service. TK-733 is typically used for the reduction of metals, asphaltenes and Conradson Carbon as a first-stage catalyst in composite catalyst fillings. The optimized pore system and...

    TK-743

    TK-743 is a demetallization catalyst with moderate hydrodesulfurization (HDS) activity for fixed-bed resid service and vacuum gas oil (VGO) hydrotreating. It is typically used for reduction of metals, asphaltenes and Conradson Carbon Residue (CCR) as a first-stage catalyst in composite catalyst...

    TK-753

    TK-753 is a transition catalyst in fixed-bed resid hydrodesulfurization (HDS) systems. In such applications, it would be preceded by a hydrodemetallization (HDM) type catalyst and followed by a HDS-type catalyst (like TK-773). TK-753 exhibits good HDS activity and HDM selectivity. The pore size...

    TK-773

    TK-773 is a final-stage catalyst for fixed-bed resid hydrodesulfurization (HDS) units. It has a high HDS, hydrodenitrogenation (HDN) and Conradson Carbon Residue (CCR) removal activity and, as such, has a low hydrodemetallization (HDM) selectivity. The pore size distribution and pore volume have...
