Embodiment 1

[0033] a. Preheating: Add 160 parts by weight of reaction raw material alumina with a particle size of 60~150 μm and 80 parts by weight of reaction raw material petroleum coke with a particle size of 100~150 μm, respectively, through their respective belt scales. The pre-mixing silo, the mixture is quantitatively fed to the electric induction heating furnace through the discharge valve, and the feeding amount of the electric induction heating furnace is calculated by two belt scales and the pre-mixing silo weighing instrument, the pre-mixing silo and the electric induction heating The furnace is sealed with the outside world, and the nitrogen is continuously ventilated, and the nitrogen gas is replaced during the start-up. After the start-up, the nitrogen gas maintains a certain pressure to prevent the chlorine gas from returning to the chlorination furnace. The mixture is heated to 1000°C by an electric induction heating furnace. Considering that the chlorination furnace as a ...

Abstract

An industrial production process of aluminum trichloride consists of an electric induction heating furnace, a chlorination furnace containing chlorine gas sieve plate and a slag discharge pipe, an aluminum powder feeding bin, a three-stage series-connected quenching jacket and three connected three-chloride The aluminum product silo, chlorine pipe, tail gas pipe, cyclone separator, and vibrator are composed. The reaction raw materials alumina and petroleum coke are heated by the electric induction heating furnace and then enter the chlorination furnace. The reaction raw material aluminum powder is fed from the aluminum powder feed bin Entering the chlorination furnace, chlorine gas enters from the bottom of the chlorination furnace through the chlorine pipe, and after being evenly distributed through the sieve plate at the bottom of the chlorination furnace, the alumina, petroleum coke, and aluminum powder are in a fluidized state in the chlorination furnace. The reaction produces aluminum trichloride, and aluminum trichloride products of different specifications are collected separately through rapid cooling. The slag in the chlorination furnace is discharged from the bottom of the chlorination furnace, and the tail gas is absorbed through three-stage spraying and comprehensively utilized.

Description

technical field [0001] The invention belongs to the field of inorganic fine powder materials, and in particular relates to a process for industrially producing aluminum trichloride. Background technique [0002] Aluminum trichloride is an important inorganic chemical. Its industrial product is light yellow granule or powder due to its green content, with a relative density of 2.44 grams per cubic centimeter (25°C), an apparent density of 1.23 grams per cubic centimeter, and a melting point of 190°C. (0.25MPa), strong water absorption, easy to deliquescence, exposed to the air, easy to absorb water and decompose to produce hydrogen chloride, easy to explode when exposed to water or steam, and highly corrosive. Aluminum trichloride is widely used in petrochemical and other fields. [0003] Most domestic manufacturers of aluminum trichloride adopt the aluminum ingot melting method, that is, the aluminum ingot is heated and melted, put into a chlorination reaction furnace, react...
