Abstract

The invention provides a novel composite fuel oil desulfurization adsorbent, a preparation method and application thereof. The novel composite fuel oil desulfurization adsorbent comprises the following components by weight: 10-20 parts of molecular sieve raw powder, 10-20 parts of Al2O3, 40-60 parts of water glass, 5-15 parts of a metal salt and 1-6 parts of an organic ligand. According to the invention, integral molecular sieve particles are adopted as the carrier, on which a metal organic skeleton with high desulfurization activity is loaded, and finally an integral hierarchical pore molecular sieve@metal organic skeleton composite desulfurization adsorbent can be obtained, and the problems of low desulfurization precision, low sulfur capacity and the like in the prior art are solved. The desulfurization adsorbent provided by the invention has high removal efficiency on thiophene sulfides, has high selectivity on sulfides, is environment-friendly and has no secondary pollution. The operation can be performed under normal temperature and normal pressure, and the operation cost is saved.

Description

technical field [0001] The invention relates to fuel oil desulfurization and adsorbent technology, in particular to a novel composite fuel oil desulfurization adsorbent, its preparation method and application. Background technique [0002] At present, the contradiction between human's increasing demand for energy and environmental pollution has become a global hot issue. Despite the rapid development of clean energy such as solar energy, wind energy, and tidal energy, there are still many difficulties to be overcome to replace traditional fossil energy. The combustion of fossil energy will produce a large amount of pollutants, causing environmental pollution. Fuel oil is a widely used fossil energy, and the sulfur oxides produced by the combustion of sulfide in fuel oil are the main cause of acid rain pollution. Environmental regulations to reduce fuel sulfur levels have been ongoing for the past two decades. The U.S. Environmental Protection Agency (USEPA) sets the optim...
