The development of catalysts possessing high activity and high stability in the catalytic hydrotreatmentof pyrolysis oils (bio-oil) is of great interest. NiCu bimetallic catalytic systems are very attractive for usein hydrotreatment process due to their low price and high activity in hydrogenation, hydrodeoxygena-tion and hydrocracking reactions. In the present work P-/Mo-containing agents were used to modifybimetallic catalytic system NiCu/SiO2–ZrO2to improve its mechanical strength and stability in acidicmedium. The modified catalysts were tested in hydrodeoxygenation (HDO) of guaiacol—a well-knownmodel compound of bio-oil. HDO process has been carried out in an autoclave at 320◦C, 17 MPa initialhydrogen pressure, reaction time 1 h. It was shown that phosphorus and molybdenum addition to thecatalysts composition results in the decrease of guaiacol conversion and deoxygenation degree. The yieldof undesirable gaseous reaction products (mainly methane) and coking of the catalyst were lower forthe modified catalysts in contrast to the initial NiCu/SiO2–ZrO2system. The catalysts treatment in glacialacetic acid at 118◦C showed that modification by P and Mo gives a significant improvement of catalystsstability in acidic medium (mass loss decreases from 53 wt.% to 1 wt.%). Also a significant improvementof bulk crushing strength has been observed for PMo-modified samples (from 0.5 MPa to 1.2 MPa).
