Biodiesel & Renewable Diesel Purification & Upgrading

SERVING CUSTOMIZED ADSORBENTS AND CATALYSTS
FOR ANY BIOFUEL FEEDSTOCK

The processing of biodiesel, renewable diesel and sustainable aviation fuel requires specialty adsorbents and catalysts for efficient, sustainable conversion in downstream production processes.

Clariant has developed a whole range of solutions to support bio- and renewable diesel producers along many steps of the value chain. 

It is vital to have the right adsorbent for your feedstock type, process conditions and refining targets, since renewable feedstocks used for this application contain phosphorus and other contaminants that poison the catalyst.

Our advanced specialty adsorbents purify biodiesel and renewable diesel feedstocks, while our catalysts are engineered to enhance reaction efficiencies.

Tonsil®

IN THE BIODIESEL PROCESS

Our best in class specialty adsorbents remove contaminants from feedstocks during pretreatment and from the reaction product during post-treatment. 
Depending on downstream demands, they can be used in wet bleaching as well as dry bleaching while providing excellent filtration properties.

Tonsil®

IN THE RENEWABLE DIESEL PROCESS

While the reaction product is a true hydrocarbon not needing post-treatment, our adsorbents fulfill the essential role of purifying feedstocks in pretreatment to prevent catalyst poisoning and other issues (as they do in the biodiesel process).

Different approaches in

BIO- AND RENEWABLE DIESEL FEEDSTOCK PURIFICATION PROCESS

Feedstocks for the production of hydrotreated vegetable oils (HVO) and fatty acid methyl esters (FAME) share common contaminants and the HVO pre-treatment process requires lower impurity levels to protect the hydrotreating catalyst. Moreover, alternative feedstocks, such as used cooking oil (UCO), animal fat, and palm oil mill effluent (POME), often contain phosphorus compounds and metal contaminants which make the adsorption process more complex.

With our Tonsil® RNF series specialty adsorbents, bio- and renewable fuel producers significantly enhance the efficiency and economics of their production process by removing harmful impurities, thus prolonging the lifetime and efficiency of the high value catalysts further downstream

Customized solutions

FOR ALL YOUR PURIFICATION NEEDS

Clariant offers industry-leading specialty adsorbents with specific physical and chemical properties engineered to reliably remove a broad range of contaminants from various feedstock types, as described above

 

Our renowned TONSIL® RNF brand includes an extensive selection of natural and activated bentonite bleaching claysdesigned to ensure the effective removal of impurities while minimizing feedstock losses and process disturbances. These specialty adsorbents are suitable for both pre-treatment of the feedstock (HVO, FAME) and post-treatment of the finished product (FAME).

 

At Clariant we are continuously developing solutions to address the increasing complexity posed by variability in renewable fuel feedstocks. Our technical experts can provide customized solutions to improve your processes and optimize your cost efficiency to give you peace of mind for your feedstock sourcing.

State-of-the-art catalysts

TO UPGRADE BIOFUELS

For decades, Clariant’s catalysts have been used for the distillate upgrading process with great success. Our catalysts help to make biodiesel into a premium product, thus making its production more economically attractive. 

  •  NiSat® 310 - proven performance in aromatics reduction of low-sulfur feedstocks such as kerosenedieselbase oilswhite oils, and bright stocks. The catalyst allows cost-effective aromatic saturation to reduce the smoke point of low-sulfur jet-fuel blending components or increase the cetane number of ultra-low sulfur diesel (ULSD) blending components. Furthermore, NiSat 310 RS can be used for the hydrogenation of vegetable oil to hydrogenated vegetable oil (HVO).
  • The isomerization catalyst HYSOPAR® 7000 can upgrade cold flow properties of hydrogenated vegetable oil (HVO), also known as renewable diesel.
  • The dewaxing catalysts HYDEX® C, HYDEX® E, and HYDEX® G can be used for bio-feedstock coprocessing. Catalytic dewaxing is an important process to boost fuel quality, while minimizing costs and by-product formation.
