APPLICATIONS & SOLUTIONS
Chemicals and Petrochemicals
The growth and increasing economic power of the middle class globally will drive demand for more advanced and smarter products from the chemical industry. At the same time, the industry is trying to decouple growing demand from increased hydrocarbon consumption. Manufacturers are investing heavily to create value using renewable resources, with leading companies setting ambitious targets to achieve net-zero greenhouse gas emissions by 2050. Consumers and shareholders alike value better carbon efficiency and reduced emissions.
From enabling cost-efficient synthesis and purification of large-scale chemicals, to helping manufacturers minimize their water footprint, Jacobi is a partner to the chemicals and petrochemicals industry. Our customers rely on our extensive product line and our technical experts to help them maintain reliable, energy- and cost-effective manufacturing of existing and new products, while minimizing water and waste impact.

Biodiesel purification
Biodiesel is produced by the trans-esterification of natural triglycerides with methanol
Glycerin is a by-product of the trans-esterification which has to be removed before biodiesel use. Biodiesel purification can be achieved using a dry Strong Acid Cation in the H+ form. The resin can be washed with methanol when its adsorption capacity is reached.
Product: Resinex DK-8
Solvent purification
Methanol purification
Metal impurities such as iron and manganese in crud methanol form an unwanted precipitate during neutralization and distillation to recover purified methanol. Precipitation can be prevented by treating crud methanol with a Strong Acid Cation in H+ which removes Mn2+ and Fe3+ before neutralization and distillation. The resin is regenerated with sulfuric acid
Product: KP H series
Resinex KP H can be also employed to remove amine impurities form methanol. In that case, as the amines concentrations are low, depending on the size of the system, the resin can be for one-way-use.
Phenol purification
In the cumene reaction for phenol production, the 2 products phenol and acetone are recovered by distillation. Before distillation, it is necessary to remove acidity. Phenol deacidification can be achieved using a Weak Base Anion resin such as Resinex CAT-23. The resin is conditioned with methanol at start-up and for the regeneration with caustic soda (sweetening-on, sweetening off).
After distillation, remaining impurities of same molecular weight as phenol (e.g. methylstyrene, acetophenone…) can be removed by condensation with phenol which produces easily separable high boiling products. A Strong Acid Cation resin in H+ form as Resinex CAT-9 can be used as catalyst for this condensation reaction.
Catalysis
The use of ion exchange resins as catalysts is well established and has increased the sustainability of making a host of well-known products. Ion exchange catalysts are a green chemistry solution because they can be reused many times, enable minimal energy consumption, and reduce the handling of hazardous materials.
Jacobi’s portfolio of heterogeneous catalysts are designed to provide excellent diffusional access, selectivity, and mechanical stability for each major reaction type, ensuring maximum yield and throughput in the process. Our products are engineered to withstand many cycles of industrial use, leading to a cost-effective solution.
We offer specialised catalysts for the following processes:
- Base catalysis
- Synthesis of bisphenol-A used in polycarbonates and epoxy resins
- Synthesis of 1,4-Butanediol for polymers and solvents
- Etherification to make fuel additives such as MTBE, ETBE, and TAME
- MIBK synthesis for rubber, coatings, adhesives
- MEK synthesis
- Phenol alkylation to produce detergents for lubricants
- Butylene hydration to produce tert-butyl alcohol (TBA)
- Isobutyle dimerization to produce isooctane
