Buss ChemTech is a leading technology supplier in the field of hydrocarbon resins, both base (HCR) and hydrogenated ones (HHCR).

Naturally, our technology is centred around the proven performance characteristics of the Buss Loop® Reactor, which achieves the highest mass transfer rates for the hydrogenation in comparison to other technologies. Our HCR technology allows clients to reduce solvent usage, minimize catalyst consumption and deliver consistently high quality water white resins. Our experience also includes partial and selective hydrogenations.

The distinctive feature of our hydrogenation technology is the continuous operation mode with a uniquely integrated catalyst filtration concept. Cutting edge solutions for polymerization are available on demand.

Our competence in the oleochemicals market segment is rooted to the origin of the BUSS-Loop® Reactor, unrivalled till nowadays since the earliest applications in Latin America in the 1950's.

Millions of tons of Fatty Amines, Nitriles, Alcohols, Esters, have been manufatured woldwide with our technology and helped to make people's life better. Mastering the design of the gas circuit of the loop reactor is a key technology requisite leadership in its applications for the oleochemicals, the gas phase often having a crucial effect on equilibrium of the relevant reactions.

In every polymer and oligomer production process there is at least one essential step in the liquid solution or slurry phase.

The BUSS-Loop® Reactor can perform successfully for this step, even at moderate viscosities, in modification processes of the base macromolecule to functionalize it, to modify its features, or its performance.

For decades, BUSS-Loop® Reactor Technology has successfully been used for the production of sorbitol and other sugar alcohols.

Sorbitol and its derivatives are used as ingredients in toothpaste and cosmetics as well as in foods and beverages. Sorbitol is an intermediate in the synthesis of Vitamin C and also in the production of a wide range of industrial chemicals used to make resins, adhesives, and additives for processing textiles, metals, paper and leather.

Other important sugar alcohols include maltitol, xylitol and lactitol which are used primarily as food additives.

Buss Loop® Reactor Technology for sorbitol and other sugar alcohols is based on hydrogenation of the corresponding sugar with two differ-ent catalyst systems: ruthenium (Ru/C) or Raney-nickel as slurry-phase catalyst.

Numerous plants have been designed and constructed using BUSS ChemTech's process and Hydrogenation Technology for the production of Sorbitol, Xylitol, Lactitol, and other sugar alcohols.

Continuos hydrogenation process is available too, on demand.

In the construction industry, despite the introduction of many novel compounds, the traditional materials have been subject to continuous innovation and improvement.

In modern concrete, chemical admixtures continue to play a crucial role, with superplasticizers standing in the center of the technology. For polycarboxylate superplasticizers (PCEs) only, current global production volume far exceeds 10 million tons per year - even after more than 40 years from their invention.

They are essentially polyethylene glycol (PEG), which are produced starting from various molecules to which a polyether chain is added by ethoxylation, obtaining the desired “x-PEG”.

Since its breakthrough in Ethylene Oxide Derivatives with the alkoxylation process performed using the BUSS-Loop® Reactor, BUSS ChemTech accompanied industry leaders and new producers in their effort to serve the market with innovation and high standards.

Our planet’s journey is a challenge to scientists, chemists, engineers and everyone trying to find sustainable solutions.

One target, among others, is the reduction of CO₂. This can be done by reducing emissions but also by capture and re-use of the remaining emissions ones.

Buss ChemTech participates in this collective effort and has already made its technology available for successful development.

Polyurethanes are among most versatile polymeric materials, moldable in different forms and shapes that are found in various industrial and consumer products.

Polyurethanes are formed by reacting a polyol (an alcohol with more than two reactive hydroxyl groups per molecule) with a diisocyanate or a polymeric isocyanate in the presence of suitable catalysts and additives.

The variety of diisocyanates and of polyols is wide and leads to many formulations and applications, so that polyurethanes can be found in mattresses, couches, insulation, liquid coatings and paints, soft flexible foam toys, tough elastomers such as roller blade wheels, some elastic fibers, and many other products.

Diving into the building blocks that make polyurethanes, once again the versatility of BUSS ChemTech technology can play a role, both on the Isocyanates and Polyols side.

Aniline and Toluenediamine (TDA) are the precursors of methylene diphenyl diisocyanate (MDI) and toluene diisocyanate (TDI) respectively, and can be respectively obatined by hydrogenating in the BUSS-Loop® Reactor nitrobenzene (NB) and dinitrobenzene (DNB).
