Manufacturing method of industrial hashane
I. Introduction
Industrial hashane is an important raw material for the production of chemicals, which is widely used in detergents, solvents, paints, coatings and other fields. With the increasing market demand, the manufacturing method of industrial hashane has also become a hot spot of research. In this paper, a common manufacturing method of industrial hashane will be introduced.
II. MATERIALS AND METHODS
1. MATERIALS
This manufacturing method mainly uses naphtha as the raw material, which is a kind of light petroleum product, and its main components are hydrocarbons.
2. Methods
The manufacturing method of industrial hashane mainly adopts catalytic reforming technology, and the specific steps are as follows:
(1) Pretreatment: naphtha is pretreated with desulfurization, dehydration and other pretreatments, so as to ensure that the catalytic reforming process is carried out smoothly.
(2) Catalytic reforming: Under the action of catalyst, the hydrocarbon compounds in naphtha undergo reforming reaction to generate hydrogen, methane, ethane, propane and other low-carbon hydrocarbon gases and liquid aromatic hydrocarbons and cycloalkanes.
(3) Separation: The industrial hashane in the liquid product is separated by separation techniques such as fractional distillation.
(4) Refining: the separated industrial hashane is refined to remove the impurities in it and obtain industrial hashane with higher purity.
III. Results and Discussion
1. Results
Through catalytic reforming technology, we can make industrial hashane with higher purity from naphtha. The specific yield and purity are affected by the quality of feedstock, catalyst type, reaction conditions and other factors.
2. DISCUSSION
In the manufacturing process of industrial hashane, the selection and use of catalysts are very critical. Different catalysts have different activities and selectivities under different reaction conditions, so it is necessary to choose the appropriate catalyst according to the specific situation. In addition, the control of reaction conditions also has a great influence on the quality and yield of the product, which needs to be optimized according to the actual situation.
IV.CONCLUSION
Industrial hashane is an important raw material for the production of chemicals, and industrial hashane with high purity can be manufactured from naphtha by catalytic reforming technology. In the specific manufacturing process, attention needs to be paid to the selection and use of catalysts and the control of reaction conditions to ensure the quality and yield of the product. The manufacturing method introduced in this paper is feasible and can provide reference for practical production.
