Abstract

A reactor for distribution modulation of Fischer-Tropsch synthesis products and application thereof belong to the technical field of hypergravity reactor. The reactor comprises a sealed reactor shell, a rotor fixed with catalyst bed layers, a rotating shaft, an end cover, a reactant inlet and a reactant outlet. A rotor of a rotating packed bed catalytic reactor is provided with multiple concentric ring-type catalyst bed layers therein; an interlayer heat transfer section is arranged between every two catalyst bed layers, the interlayer heat transfer section is a concentric ring formed by multiple separated casings or heat pipes surronuding the center of the rotor; the end cover is provided with a heat transfer medium inlet and outlet devices; and the outer edge of the rotor is provided with blades. The rotating packed bed catalytic reactor changes the variety and amount of catalyst and inner structure and hypergravity level of the hypergravity reactor to synthesize products with specific component distribution with high selectivity. The hypergravity rotating packed bed catalytic reactor with a novel structure of the invention has advantages of orientated production of the target product, good heat and mass transfer performances and long service life of catalyst, etc.

Description

technical field [0001] The invention relates to a reactor for regulating the distribution of Fischer-Tropsch synthesis products, in particular to a rotary packed bed catalytic reactor with a multi-layer rotor and a heat exchange section composed of concentric ring catalyst layers, which belongs to the supergravity reaction device technology field. technical background [0002] Synthesis gas (CO, CO 2 and H 2 mixed gas), and then use syngas as raw material to produce liquid hydrocarbons through Fischer-Tropsch synthesis, which is a good oil replacement technology. Fischer-Tropsch synthesis (Fischer-Tropsch process), also known as F-T synthesis, is a technical process of synthesizing liquid fuel mainly composed of paraffin hydrocarbons with synthesis gas as raw material under catalyst and appropriate conditions. The Fischer-Tropsch synthesis reaction has a history of more than 80 years, and Sasol, PetroSA, Shell, and Oryx have relatively large-scale Fischer-Tropsch synthesi...
