![]() ![]() Without hydrofracking, it would be difficult to access energy resources that are available in oil shale, tight oil and coal seam gas. It brings about an efficient form of energy. ![]() There are many pros and cons that are associated with it, and they are important to consider while coming up with an opinion on this controversial topic. ![]() More than half of the world’s hydrofracking operations that had occurred in the last seven decades happened in the US. The method is a well-stimulation technique that uses pressured liquids to fracture rocks. Pulse reaction test method determined the activity of the metal function at near reaction condition on the sulfided catalysts.Hydraulic fracturing, or commonly known as hydrofracking, has become a hot point of contention today in many areas as the US attempts to gain more energy independence from the rest of the world. ![]() A direct relationship was observed between the acidity of the catalysts and VGO conversion. Nickel and molybdenum were impregnated as active metals on 0.8 mm extrudates of silica-alumina supports prepared with an alumina binder. In addition to the prepared catalyst, one commercial catalyst was also evaluated for comparison purposes. The hydrocracking activity of all the prepared catalysts was measured using Arabian heavy VGO as feed in a swing type autoclave reactor. The characterization results are discussed in relation to the catalytic activities in hydrocracking reactions. A series of amorphous silica-alumina and zeolite based first stage hydrocracking catalyst was prepared, characterized for acidity measurement by temperature programmed desorption of ammonia (TPD), pulse reaction test (PRT) method for hydrogenation/dehydrogenation activity and evaluated for vacuum gas oil (VGO) conversion. An attempt has been made to measure the metal function by cyclohexane dehydrogenation reaction. Determination of acidity is straight forward but direct measurement of the metal function of bi-functional hydroprocessing catalyst is a complicated procedure. For the better performance of hydrocracking catalyst a balance is required between the acid function and hydrogenation/dehydrogenation function of the catalyst. ![]()
