New Catalyst Helps High Methanol Production and Low Consumption

Recently, the NC310 methanol synthesis catalyst developed by Nanhua Research Institute passed the appraisal of scientific research achievements organized by the Ministry of Science and Technology of Sinopec. The identification expert group believes that the overall performance of the catalyst has reached the international advanced level. Up to now, the catalyst has been applied industrially for two years in a synthetic methanol plant with an annual output of 150,000 tons. The results show that the catalyst has good activity and stability, high methanol output, low unit consumption, and high grade of by-product steam. Significant economic benefits.

In recent years, the large-scale equipment has put forward higher requirements for methanol synthesis catalysts. In order to make full use of the reactor volume and obtain high methanol yield, the catalyst must have higher activity, longer service life and lower shrinkage. Nanhua Research Institute developed NC310 methanol synthesis catalyst on the basis of methanol synthesis catalyst C307. The catalyst adopts a reasonable formula and advanced binary precursor preparation technology, so that the content of surface active components is relatively high and the activity is better; the colloidal carrier prepared by using a special carrier preparation technology has a specific crystal form and a reasonable size distribution , so that the catalyst has a suitable pore size distribution, which is beneficial to the mass transfer and heat transfer in the methanol synthesis reaction process, and improves the selectivity and stability of the catalyst.

At present, the catalyst preparation technology has applied for 8 Chinese invention patents, 3 of which have been authorized.
