Background

Catalytic reforming: the process of rearranging the molecular structure of hydrocarbons in gasoline fraction into new molecular structure under the condition of catalyst action is called catalytic reforming. One of petroleum refining processes is a process of converting a light gasoline fraction (or naphtha) obtained by distilling crude oil into a gasoline (reformed gasoline) rich in aromatic hydrocarbons and having a high octane number, and by-producing liquefied petroleum gas and hydrogen, under the conditions of heating, hydrogen pressure and the presence of a catalyst. The reformed gasoline can be directly used as a blending component of gasoline, and can also be extracted by aromatic hydrocarbon to prepare benzene, toluene and xylene. The byproduct hydrogen is an important source of hydrogen for hydrogenation devices (such as hydrofining and hydrocracking) in petroleum refineries.

The catalytic reforming is to rearrange the molecular structure of hydrocarbons by using a catalyst and to produce a large amount of hydrogen as a byproduct. The principle of the cracking is that different components in the petroleum are subjected to processing of short-chain hydrocarbons such as different boiling points and propylene or benzene, and the cracking is deep cracking, but at the initial stage of separation of dust and oil gas, a part of heat can be taken away by the separated dust to reduce the temperature of mixed gas, so that the separation of the dust and the oil gas at the later stage is influenced, meanwhile, the ash blocking plate of the existing sediment tank mostly adopts a fixed structure, and the separated dust is easy to gather on the ash blocking plate, so that the separation effect degree of the oil gas is influenced.
