Production of acrylic acid catalyst with highest yield and purityprocess
Acrylic acid is one of the main products of the downstream industry chain of propylene, which is easy to degrade. The downstream products mainly include acrylic acid ester, polymer water absorbent resin (SAP), washing aid, special acrylic acid ester, water treatment agent, etc., which is the upstream raw material supporting the development of important industries such as paper making, coating, textile, home health, leather and building materials. It is an important driving force to promote the development of propylene industry, and the market space is extremely broad.
The propylene oxidation to acrolein/acrylic acid catalyst is mainly used in the acrolein production plant or for the two-stage oxidation process to produce acrylic acid device, including two catalyst products: GR-AC1 is the first stage catalyst for the oxidation of propylene to acrolein, and GR-AAI is the second stage catalyst for the oxidation of acrolein to acrylic acid. The catalyst has the characteristics of high propylene conversion, good product selectivity and high flexibility in process operation.
The catalyst belongs to the coated spherical system catalyst, which is stable in operation and operation. It has the ability of stable operation at high propylene airspeed, high propylene conversion rate and good product selectivity.
Shanghai Guanru Chemical Co., Ltd. is a professional enterprise in the research, production and sales of chemicals.The products developed and produced by the company are widely used in pulp and paper industry, textile printing and dyeing industry, architectural coating industry, surface cleaning industry, chemical industry, petroleum industry, sewage treatment industry, etc. Quality is excellent, products are superior; supply is timely, and service is thoughtful!
Supply "Excellent Quality + Reasonable Price + Specialized Services" is our development tenet. The company have scientific management, strong technology and sincerely service system. We welcome customers all over the world visit for business negotiation on the basic of sincerely cooperation and mutual benefit!

Propylene oxidation method
In 1969, UCC created the oxidation process for acrylic acid. This production method is initially divided into a one-step method and a two-step method, but the two-step method is more conducive to improving the selectivity of the catalyst, so the two-step oxidation of propylene is selected in the production process to produce acrylic acid. This method is so far the longest use time, and the product yield and purity of the highest process, the pollution to the environment is also very small, so far the production plant has experienced 40 years of device calibration, propylene oxidation method is the most mature production process. The main reaction is the oxidation of propylene to acrolein in the first step and the oxidation of acrolein to acrylic acid in the second step, during which a catalyst is needed to accelerate the main reaction rate and selectivity. So far, the world's enterprises mainly use this process to produce acrylic acid.
