Received: 7 August 2020; Accepted: 11 September 2020; Published: date Supporting information about the material preparation Chemical and Reagents. The other supports used in this paper including active carbon, SiO2, and MgO were achieved though commercial approach and were utilized without further purification. The cock husk granule active carbon particles (2-4 mm), SiO2 support (600-800 mesh, AR), MgO support (AR), 2 and Al-MCM-41 (SABET = 400-700 m /g, PDavg = 3-5 nm) were provided by local suppliers. Material Preparation. Synthesis of 5%Ru/other supports. The synthesis of other support is performed through the wet impregnation method, which is almost similar to the preparation of 5%Ru/γ- Al2O3@ASMA pellet catalyst but without the encapsulation process. All the supports were sonicated in water for 30 min to remove the surface impurity and dried at 105ºC overnight for further usage. Ru species of 5% by weight were introduced into the other support through the conventional wet impregnation method. 2.0 g other support were transferred into the round bottom flask with the prestaging RuCl3 ethanol solution of 0.2053 g RuCl3 and refluxed for 12 h with continuous stirring at 78ºC. The impregnation process was finished when the solvent fully evaporated. The resulted samples were collected, washed, and dried at 105ºC overnight. Before being applied in the hydrogenation reaction, the as-prepared 5%Ru/other support precursor was placed in a batch reactor filled with 5 MPa H2 at 120ºC for 3 h. After washing with water to remove the residue chlorine ions and dried, the target peer samples 5%Ru/active carbon, 5%Ru/SiO2, 5%Ru/MgO, and 5%Ru/MCM-41 catalyst can be achieved. Table S1.
