The source technology of the nitrogen fertilizer and chemical raw materials industry chain is the ammonia synthesis production process. The coal head route is to gasify raw coal to produce crude gas, and after transformation, carbon removal, and sulfur removal purification, qualified hydrogen-nitrogen gas is obtained; the gas head route is to convert natural gas into syngas, with a shorter process and relatively low carbon emissions. After purification, the nitrogen-hydrogen mixture gas is compressed and synthesized into ammonia under high temperature and pressure using an iron-based catalyst, and the liquid ammonia is separated and recycled to the system. Both routes have been implemented in engineering applications and have a mature industrial operation base, which can be selected according to the coal or natural gas resources available at the site of the owner. The product liquid ammonia can be further processed into urea, ammonium nitrate, or sold directly as a chemical raw material. Services such as feed route selection, plant-wide process package design, key equipment selection for gasification and synthesis systems, catalyst selection, start-up guidance, and operation training are available.

The key link in the downstream extension of oil and grease chemical industry is the technology of fatty acid methyl ester hydrogenation to fatty alcohols: fatty acid methyl ester and hydrogen gas react under the action of a catalyst to produce fatty alcohols, which are then separated by distillation and decarbonized to obtain alcohols with different carbon chain lengths. The products cover the C8-C18 series of fatty alcohols, which are important raw materials for surfactants, detergents, plasticizers, and cosmetics. This route is suitable for the layout of oil and grease chemical parks using natural oils such as palm oil and coconut oil as raw materials, and can also be combined with fatty acid and glycerol plants to form a complete industrial chain. The technology has been implemented in industrial applications and has a mature basis for industrialization. The owner must have hydrogen supply conditions. Services such as process package authorization, hydrogenation reaction system base design support, catalyst selection and filling scheme, distillation system equipment selection recommendations, commissioning guidance, and operation training are available.
