Catalysts were tested in simultaneous reactions of dibenzothiophene (DBT) and o-xylene under typical hydrotreating conditions.
The prepared catalysts were characterized by nitrogen physisorption, small-angle and powder X-ray diffraction (XRD), UV vis diffuse reflectance spectroscopy (DRS), temperature-programmed reduction (TPR), high resolution transmission electron microscopy (HRTEM) and tested in simultaneous HDS of dibenzothiophene (DBT) and 4,6-dimethyldibenzothiophene (4,6-DMDBT) in a batch reactor at 300 °C for 8 h.
The performance of the evolved strain was also tested in simultaneous saccharification and fermentation using both pretreated Arundo and spruce material.
Simultaneous presentation Each subject was first tested in the simultaneous condition.
Sulfided catalysts were characterized by HRTEM and tested in the simultaneous HDS of dibenzothiophene (DBT) and 4,6-dimethyldibenzothiophene (4,6-DMDBT).
The catalysts were sulphided in situ and subsequently tested in the simultaneous dibenzothiophene (DBT HDSS and tetralin (THN) hydrogenation reactions in a high pressure batch reactor at 613 K and 70 bar.
Supports and catalysts were characterized by nitrogen physisorption, small-angle and powder XRD, thermogravimetric analysis (TGA/DTG), temperature programmed reduction, UV vis DRS, HRTEM, and tested in the simultaneous HDS of dibenzothiophene (DBT) and 4,6-dimethyldibenzothiophene (4,6-DMDBT).
Supports and catalysts were characterized by nitrogen physisorption, small-angle and powder XRD, TPR, UV vis DRS, HRTEM, and tested in the simultaneous HDS of dibenzothiophene (DBT) and 4,6-dimethyldibenzothiophene (4,6-DMDBT).
However, many of these findings have been recently challenged by a study of Minini and Jeffery [146], who concluded that rats, when tested in a simultaneous (i.e., a two-alternative forced-choice) discrimination task, do not spontaneously rely on a shape-based recognition strategy, at least when other lower-level visual cues are available to successfully accomplish the task.
The technique is first tested in laboratory experiments with simultaneous registration of the ground reaction forces.
The catalysts were tested in the vapor-phase simultaneous hydrogenation (HYD) of naphthalene and toluene in the presence of dibenzothiophene (DBT; 100 ppm of S) at 5 MPa of total pressure.
