Embodiment 1

[0019] use as figure 1 In the process flow shown, oil and gas enter the central pipe (5) directly from the oil and gas inlet (1) at the top of the reactor, and enter the catalyst bed after passing through the central pipe network. The oil and gas radiate to the surroundings through the catalyst bed and then enter the fan-shaped cylinder (4) along the wall, and then enter the manifold from the bottom of the fan-shaped cylinder (4), and then flow out from both sides and enter the next equipment. The oil and gas inlet (1) is connected with the reactor by a flange (2). The catalyst enters from the catalyst inlet (3), and flows out from the catalyst outlet (6) to the next device by its own gravity.

[0020] The flow direction of the oil and gas in the reactor of the present invention is "from the inside to the outside", and the fan-shaped cylinder is used instead of the sleeve and the outer cylinder with multiple hollow walls. The fan-shaped cylinder structure is more solid and re...

Embodiment 2

[0022] The reforming reactor with the same structure as in Example 1 is used, the difference is that after the reforming reactor, the oil gas enters the manifold from the bottom of the fan-shaped cylinder (4), is exported from both sides and then enters the catalyst filter through the oil gas outlet. The catalyst filter adopts a cylindrical structure. The oil and gas inlet of the catalyst filter is in the middle of the cylinder, and the lower part is conical. The oil and gas outlets of the filter are connected.

[0023] The catalyst filter structure provided by the invention is particularly suitable for the catalytic reforming process with a reforming reactor with a special structure, which improves product quality and maintains long-term operation of the device.

Abstract

The invention relates to a catalytic reforming method. According to the catalytic reforming method, oil gas is delivered into a central tube via an oil gas inlet arranged on the top of a reforming reactor, and is subjected to contact reaction with a catalyst; after reaction, oil gas is delivered into a collecting tube via a fan-shaped barrel, and is discharged out of the reforming reactor via an oil gas outlet. According to the catalytic reforming method, flow direction of oil gas in the reactor is changed; connection of internal components is avoided, contact area of the catalyst with oil gas is enlarged, residence time of oil gas on the catalyst is prolonged, problems caused by catalyst leakage are prevented or reduced, and product quality is improved at a same severity.

Description

technical field [0001] The invention relates to a continuous catalytic reforming process for petroleum processing. Background technique [0002] Catalytic reforming unit is an important process of petroleum secondary processing. It is a catalytic reaction to produce high-octane gasoline components and aromatics from low-octane straight-run naphtha under the action of a catalyst through a series of special reactions. process. The reforming reactor is an important equipment of the reforming unit and also the core part of the whole reforming unit. The role of the reforming reactor is to allow the hydrocarbons to contact the catalyst under reaction conditions without allowing the catalyst to leave without entraining the product. The equipment is a radial reactor, which operates in a high-temperature hydrogen-facing environment. The reactor is composed of oil and gas inlet and outlet parts, catalyst dipleg and reactor internals. The internal components include oil and gas dis...
