As a new generation of environmentally friendly hydrodesulfurization catalyst, the nickel phosphide (Ni2P) catalyst industry has broad development prospects.

Nickel phosphide catalyst, referred to as Ni2P catalyst, is a transition metal phosphide catalyst. It has the advantages of strong activity, strong dispersion, good reversible recovery, strong sulfur resistance, good environmental protection, and high stability. It is used in hydrodesulfurization , hydrodenitrification, hydrodeoxygenation, olefin hydrogenation, aromatic saturation and other fields are widely used.

There are many methods for producing nickel phosphide catalysts, mainly including nickel phosphide reduction method, hypophosphite reduction method, direct reduction method, hydrogen plasma reduction method, etc. Among them, the hypophosphite reduction method is currently the mainstream method for producing nickel phosphide catalysts. It refers to using nickel chloride and sodium hypophosphite as raw materials in a water system through mixing, drying, thermal decomposition, phosphine reduction, and water washing. The method of generating nickel phosphide catalyst in other steps has the advantages of low synthesis temperature, simple process, and easy large-scale production.

According to the “2023-2028 Nickel Phosphide (Ni2P) Catalyst Industry Market In-depth Research and Investment Prospects Forecast Analysis Report” released by the Industrial Research Center shows that the nickel phosphide catalyst has good hydrodesulfurization and sulfur resistance properties, and has broad application prospects in the field of low-sulfur fuel oil preparation. Currently, against the background of the continuous advancement of domestic dual-carbon goals and the continuous strengthening of environmental protection supervision, low-sulfur fuel oil and sulfur-free fuel oil have gradually become mainstream products in the fuel oil market, with broad market demand. Low-sulfur and sulfur-free fuel oil are mainly produced through the hydrodesulfurization (HDS) process, and HDS catalysts are the key materials to achieve this process.

Traditional HDS catalysts are mainly sulfide catalysts, which are not in line with the low-sulphurization and sulfur-free upgrade direction of fuel oil and the increasingly stringent environmental policies and regulations. The nickel phosphide catalyst is a new generation of environmentally friendly HDS catalyst with better overall performance than traditional HDS catalysts. It has gradually become a mainstream catalyst in the field of low-sulfur fuel oil preparation.

In 2022, my country’s low-sulfur fuel oil production will be approximately 15.5 million tons, a year-on-year increase of 33.5%. In recent years, driven by the rapid development of the domestic low-sulfur fuel oil industry, the market penetration rate of nickel phosphide catalysts has continued to increase, and the industry has broad prospects for development. Domestic enterprises and research institutions in the field of nickel phosphide catalyst R&D and production mainly include Wenzhou Bangxinyuan Technology, Runtai New Materials, Suzhou Dejie Membrane Material Technology, Anhui University of Technology, Changzhou University, Guangxi Normal University, etc.

Industry analysts said that nickel phosphide catalyst is a type of transition metal phosphide catalyst with good performance Chemical properties, widely used in hydrodesulfurization, hydrodenitrification, hydrodeoxygenation and other fields. Especially in the field of hydrodesulfurization, nickel phosphide catalyst is an important material for the production of low-sulfur fuel oil. As the production of low-sulfur fuel oil continues to increase, its demand continues to increase and its application prospects are broad. At present, the number of enterprises in the field of R&D and production of nickel phosphide catalysts in my country is still relatively small. The industry is still in the initial stage of development, and there is still huge room for development in the future.
