Comparison of Microwave-Assisted Digestion Methods for the Analysis of Hydrotreating Catalysts by Atomic Emission
Abstract:Nickel-molybdenum catalysts make up a large portion of hydrotreating catalysts and have very wide applications in the petroleum refining industry. They are primarily used to remove undesirable elements such as N, O, and S along with Ni, V, and Fe from petroleum feedstocks or products. They have also been useful in hydrogenation of unsaturates and hydrocracking of heavy compounds. However, they are not universal catalysts; each catalyst is designed to perform one major task in the process. In a procedure to make Ni-Mo catalysts selective for a particular reaction or improve the thermomechanical properties, promoters and modifiers are incorporated into the catalysts. Their concentrations play a crucial role in the performance of the catalyst, whether it is thermal stability or catalytic activity.
