Yueyang Sciensun chemical co., LTD. Specializes in research and development and production of refinery catalysts, so what is the catalyst? Today xiaobian sorted out some data, hope that through these data, can let the majority of new and old customers have a more systematic understanding of the catalyst.
First, let's look at catalysts. A catalyst is a substance that can change the rate of a chemical reaction without changing the thermodynamic equilibrium position of the reaction, and that is not visibly consumed by itself.
Secondly, it should be emphasized that the reaction performance of catalysts is the main index to evaluate the performance of catalysts, which mainly includes the activity, selectivity and stability of catalysts. The activity of the catalyst refers to the degree to which the catalyst can accelerate the reaction speed of the chemical reaction. The selectivity of catalyst refers to making the reaction go in the direction of producing a particular product. The stability of the catalyst refers to the period of stable activity of the catalyst under operating conditions. The process steps of heterogeneous catalytic reaction can be divided into external diffusion, internal diffusion, chemical adsorption, surface reaction, desorption, internal diffusion and external diffusion. Essentially, it can be divided into physical process, chemical process and physical process.
And finally do you know what the functions or effects of catalysts are in industry? (1) to achieve the process that was difficult to achieve in industry; From the past used to use a raw material, can be changed into a variety of raw materials; (3) the original production process, can achieve production; The original need to complete more steps, into a step to complete; From the original product quality is low, large energy consumption, into the production cost is low, high quality; From the original low conversion rate, many by-products, serious pollution, into a high conversion rate, a single product, pollution reduction.
So that's the basic information about catalysts. If you want to know more, please contact our catalyst manufacturer through this website!
