Macropore hydrogenation catalyst and its preparation method

Abstract

A macroreticular hydrocatalyst for the catalytic hydrogenation of heavy oil is prepared through providing organic particles as template agent, compounding it with carrier, and removing the template agent. It features that the diameter and ration of big pores (5-2000 nm) can be controlled.

Description

technical field [0001] The invention relates to a heavy oil hydrogenation catalyst in which macropore structure parameters can be independently adjusted and a preparation method thereof. The catalyst is suitable for the catalytic hydrogenation process of heavy oil. Background technique [0002] Making full use of heavy oil resources and making them lighter to the maximum is the goal pursued by the oil refining industry, and catalytic hydrogenation of heavy oil is one of the important means of lightening heavy oil. Today, with the rapid development of social economy, the contradiction between the high content of non-hydrocarbon impurities in heavy oil, insufficient hydrogen content and stricter emission standards for fuel oil combustion in environmental legislation has become increasingly prominent. Catalytic hydrogenation of heavy oil has become an important means of clean fuel production. appear important. In the research of catalytic hydrogenation technology, the mass tr...

Therefore, in the prior art, for the same composition, the actual range of adjustment of the pore structure parameters of catalysts prepared by the same method is quite limited

In addition, the openness of the pores is also an important indicator to determine whether the catalyst has good diffusion performance. However, the characterization of the openness of the catalyst pores has always been uncertain in the prior art.
