Loading of catalyst

Proper and reasonable loading of catalyst is the basis of effective use of catalyst. Through years of experience accumulation and research improvement, hydrogenation workers have developed a series of loading methods and equipment for hydrogenation catalyst, which can achieve multiple loading of catalysts in a reactor of a certain volume. Reduce the pressure drop of the reactor, the gas liquid distribution in the reaction process is reasonable, so as to play the catalytic function of the catalyst more effectively, improve the operation level of the hydrogenation unit, prolong the operation cycle, improve the economic benefit of the unit.

1. Catalyst inspection and sieving

Before loading the catalyst, carefully check the brand, inspection certificate and acceptance procedures of the catalyst, check the packaging condition of the catalyst, damp and pollution, so as to reasonably formulate the construction plan before starting. The catalyst will be broken in the process of transportation and loading and unloading. After regeneration, the catalyst will be broken more, as well as rust, coke and other impurities. In order to prevent the increase of pressure drop in the bed and ensure the reasonable distribution of gas and liquid during operation, it must be sieved.

2. Common loading of catalyst

The loading of the catalyst is carried out by the loading equipment, which consists of three parts, the hopper, connected to the metal pipe, then connected to the canvas hose. During loading, the catalyst is installed in the hopper, the flow of the catalyst is controlled through the gate valve, so that the catalyst is evenly spread in the reactor. According to the situation, the loading equipment is moved and the canvas hose is shortened until the loading is completed.
