The current OSHA PEL and the NIOSH recommended limit for nickel carbonyl is 0.001 ppm TWA, as Ni. Conversion of carbonyl ... Bio-oil hydrotreating is typically carried out at temperatures between2 250 and 450 °C. The main transformation processes for converting vegetable oils into liquid biofuels for transportation are transesterification, catalytic cracking and hydrotreating. [0033]The Group VIII metal component contained in the hydrotreating catalyst composition can be in the elemental form or in the form of a metal compound, such as, for example, oxides, sulfides and the like. Nickel reacts with carbon monoxide to form nickel carbonyl gas (Ni (CO)4), which can be decomposed back to nickel metal at moderate temperatures with the recovery of carbon monoxide.
