Methanol-to-olefins (MTO) is a key technology for the production of ethylene and propylene from non-petroleum sources. The third-generation MTO technology has achieved significant improvements over the previous two generations. DMTO-III employs a new generation of catalysts and a fluidized bed reaction-regeneration process: a single unit has a larger processing capacity, lower methanol consumption, higher ethylene and propylene selectivity and yield, and can increase olefin production without the addition of methanol feed; the process has a relaxed requirement for methanol feedstock, and can be flexibly connected with coal-to-methanol, natural gas-to-methanol, and imported methanol, providing a diversified olefin feedstock solution for both coal-rich regions and coastal areas. The technology has been built and commissioned in a pilot plant, which has verified the feasibility of the process and has the basis for process scaling, making it suitable for large-scale owners planning to build new coal (methanol) to olefins projects or upgrading existing MTO units. Services including process package licensing, catalyst supply solutions, basic design support, commissioning guidance, and operation training are available.

Ethanol is the basic raw material for the production of various fine chemicals such as acetic acid, glycerol, and pyridine compounds. This technology uses ethanol as the raw material and adopts a catalytic dehydrogenation route to produce ethanol: under the action of copper-based or modified catalysts, ethanol is dehydrogenated to produce ethanol and hydrogen gas, with mild reaction conditions, high selectivity, and recoverable hydrogen gas; compared with the ethylene oxidation method, this route has flexible raw material sources (biological ethanol and synthetic ethanol), a short process, low investment, and no corrosive media, making it suitable for regions with abundant ethanol resources and small- and medium-scale fine chemical supporting needs. The product scheme can be directly connected to downstream acetic acid, acetic anhydride, and other units, enabling the extension of the ethanol industry chain. This technology has been built and commissioned a pilot plant, which has verified the feasibility of the process and has the basis for process scaling. The company can provide process package authorization, catalyst selection and lifetime management recommendations, basic design support, commissioning guidance, and operation training services, with the requirement that the customer provide the necessary ethanol raw materials and hydrogen utilization or discharge conditions.

This technology uses the ethylene production and carbon utilization value of methane-CO2 coupling conversion route. Under the action of a special catalyst, CO2 assists in the dehydrogenation of methane to produce ethylene, while CO2 is reduced to CO, which together with the hydrogen produced as a by-product of dehydrogenation forms a synthetic gas product. Compared with traditional steam cracking, this route has a lower reaction temperature, lower energy consumption and carbon emission intensity, and is particularly suitable for owners with abundant methane resources (shale gas, associated gas, imported methane) and who place great importance on carbon reduction. The synthetic gas produced can be connected to downstream units for ketone synthesis, methanol production, and so on. A pilot plant has been built and commissioned, which has verified the feasibility of the process and has the basis for process scale-up. Services such as process package licensing, catalyst selection, reactor and separation scheme design, commissioning guidance, and operation training are available.

The III+ lubricating oil base oil has high viscosity index, low volatility and excellent oxidation stability, and is a core component of high-end engine oils and industrial oils, mainly relying on the hydrogenation process. This technology uses Fetoparaffin as raw material to produce III+ class base oil through the hydrogenation isomerization-supplementation refining process: Fetoparaffin has high purity and contains almost no sulfur and nitrogen aromatics, which is an ideal raw material; a special dual-function catalyst achieves selective isomerization of long-chain normal hydrocarbons, while maintaining high viscosity index and significantly reducing the boiling point, resulting in high product yield and stable quality. This technology is naturally connected to the coal-to-oil and natural gas-to-oil (GTL) industry chains, providing a path for Fetoparaffin companies to expand into downstream high-value-added products. At present, a pilot plant has been built and commissioned, which has verified the feasibility of the process and has the basis for process scaling. Services such as process package authorization, catalyst selection and supply recommendations, fractionation scheme design, basic design support, commissioning guidance, and operation training are available.

This technology is aimed at the deep utilization of naphthenic base oil, providing hydrogenation isomerization catalysts and complete processes: under high-pressure hydrogenation conditions, heavy components are refined, isomerization and selective cracking are coordinated, improving the viscosity-temperature performance and oxidation stability of the base oil, and high-quality bright oil products are obtained, filling the gap in product quality of conventional solvent refining processes. The catalysts take into account activity, selectivity, and resistance to impurities, and the process flow is well compatible with existing hydrogenation units.

2,6-Naphthalene dicarboxylic acid (2,6-NDCA) is a key monomer for high-performance polyester PEN (poly(naphthalene dicarboxylic acid, ethylene glycol ester), which is significantly superior to PET in heat resistance, gas barrier properties, and mechanical strength, and is used in high-end films, fibers, and packaging. This technology uses 2,6-dialkyl naphthalene as raw material to produce 2,6-naphthalene dicarboxylic acid by liquid-phase catalytic oxidation: through the synergistic optimization of the catalyst system and oxidation process conditions, the high-efficiency directional oxidation of the alkyl group on the naphthalene ring is achieved, and the crude product is refined to meet the polymerization level requirements.

The technology provides two production pathways: benzene hydrogenation-alkylation coupling conversion, in which benzene is used as raw material to partially hydrogenate to form a cyclopentene intermediate and then alkylate it in situ with benzene; or benzene and cyclopentene are directly alkylated.

In response to the structural contradiction between the abundance of propane resources and the shortage of light cracking feedstock, this technology selectively converts propane into ethylene and propylene through catalytic conversion. The reaction process realizes the directional restructuring of C4 alkanes into light hydrocarbons, and the products, ethylene and propylene, are high-quality feedstock for steam cracking units, significantly improving the yield of ethylene and propylene and improving the structure of the cracking feedstock.
