Overview Select 450 by Oil-Dri is a finely divided selective silicate adsorbent positioned for the reduction of soaps, phospholipids, trace metals, and other polar impurities in ed ible-oil and biofuel-processing applications. Select 450 is commonly evaluated as a pretreatment medium before bleaching, polishing, or downstream refining. By targeting impurities that may interfere with feedstock quality, filtration, processing efficiency, or finished-product specifications, it can complement bleaching earth and other purification steps within an integrated treatment system.

How Select 450 fits into a treatment process Process stage Potential role Incoming oil or feedstock Characterize soaps, phospholipids, moisture, trace elements, color, and other impurities Select 450 pretreatment Target selected polar impurities, soaps, phospholipids, and trace metals Bleaching-earth treatment Provide broader reduction of color bodies, chlorophyll, oxidation products, and additional impurities Filtration Remove spent adsorbent and retained contaminants from the treated oil Downstream refining or conversion Continue processing toward the required finished-oil or fuel specification The appropriate sequence depends on the oil or feedstock, process equipment, contaminant profile, and finished-product requirements. Packaging & availability Package Configuration 2,000 lb (approximately 907 kg) One pallet containing 40 × 50 lb (22.68 kg) bags 2,000 lb (approximately 907 kg) One bulk supersack Minimum order: Two pallets for published bagged-pallet pricing Bagged material: Forty individual 50 lb bags per pallet Bulk material: Supersacks available by request, subject to current supplier availability Lead time: Confirmed at quotation or order placement Freight: Nationwide LTL shipping with live checkout rates for eligible configurations Volume purchasing: Contact us for recurring supply, multi-pallet requirements, or delivered pricing Application and trial guidance The appropriate Select 450 dosage depends on the oil or feedstock, incoming soap concentration, phospholipids, trace-metal profile, moisture level, treatment temperature, mixing conditions, contact time, filtration equipment, and downstream specification. Begin with controlled bench trials using the actual oil or feedstock Measure the untreated feed before establishing a treatment target Evaluate multiple Select 450 dosage rates rather than assuming one universal treatment level When used before bleaching earth, optimize both media dosages together Measure soap reduction, phospholipids, trace elements, filtration behavior, oil retention, and downstream performance Confirm that treated material meets all applicable process and finished-product requirements No universal dosage is stated on this page because the proper treatment rate must be established through process testing and current manufacturer guidance. Select 450 compared with bleaching earth Media type Primary treatment emphasis Select 450 Selective pretreatment for soaps, phospholipids, trace metals, and other polar impurities Bleaching earth Broader color reduction, chlorophyll adsorption, oxidation-product removal, and oil polishing Combined treatment Sequential or integrated impurity removal where one medium alone does not meet the process target efficiently Select 450 should not automatically be treated as a direct replacement for Supreme 55, Supreme B81, B80, or another bleaching clay. The treatment sequence should be established through trials with the actual feedstock. Select 350 or Select 450? Select 350 and Select 450 are both positioned as selective silicate adsorbents for targeted oil and feedstock pretreatment. The available reference data indicate differences in moisture content and tamped density, but those figures alone do not establish which grade will deliver better contaminant removal in a specific process. Reference property Select 350 Select 450 Free moisture Less than 5.0% 10.0% pH 3.6 3.6 Tamped density 37.0 lb/ft³ 43.0 lb/ft³ Particle size 62% passing 325 mesh 62% passing 325 mesh These comparison values are based on previously supplied product information and require confirmation against current Oil-Dri documentation. Final grade selection should be based on manufacturer guidance and comparative trials. Handling & storage Store unused material in a dry, protected location Keep bags or supersacks closed until needed Minimize airborne dust during transfer, mixing, and handling Use appropriate ventilation and personal protective equipment as directed by the current SDS Avoid contact with incompatible materials identified in current manufacturer documentation Handle fresh and spent adsorbent according to the treated oil, facility procedures, and applicable regulations Important: Review a current manufacturer SDS before handling or use.

Need help designing a pretreatment trial? Adsorbent selection depends on the feedstock, soap concentration, phospholipids, metals, moisture, acidity, treatment temperature, contact time, filtration system, and downstream specification. Sorbents Direct can help compare Select 450 with Select 350 and available Oil-Dri bleaching-earth grades for controlled process evaluation. Questions & answers What is Select 450? Select 450 is a finely divided selective silicate adsorbent positioned for pretreatment and impurity reduction in compatible edible-oil, biodiesel, and industrial-oil processes. What impurities does Select 450 target? Select 450 is positioned for reducing soaps, phospholipids, trace metals, and other polar impurities that can interfere with downstream refining, bleaching, conversion, or specification compliance. Is Select 450 a bleaching clay? No. Select 450 is described as a selective silicate adsorbent and is generally positioned as a targeted pretreatment medium. Bleaching earth has a broader emphasis on color, chlorophyll, oxidation products, and oil polishing. When should Select 450 be used before bleaching earth? It may be evaluated before bleaching when soaps, phospholipids, metals, or other polar impurities are creating processing problems that bleaching clay alone does not remove efficiently. Can Select 450 be used in biodiesel processing? Select 450 may be evaluated for pretreatment or adsorptive cleanup of compatible biodiesel feedstocks. Suitability depends on the feedstock, process configuration, contaminants, and required finished-fuel specification. What is the difference between Select 450 and Select 350? Both are positioned as selective silicate adsorbents. The available reference values show differences in moisture and bulk density, but they do not establish that one grade is universally stronger or more effective. Grade selection should be based on current Oil-Dri guidance and comparative process trials. Is Select 450 stronger than Select 350? Sorbents Direct does not currently have sufficient verified manufacturer documentation to make that claim. The most efficient grade and dosage should be established using the actual feedstock and relevant contaminant targets. What dosage should I use? There is no universal dosage for all oils or feedstocks. Establish the treatment rate through controlled bench trials based on contaminant levels, process conditions, filtration performance, and downstream specifications. What is the minimum order? The current minimum order for published bagged-pallet pricing is two pallets, or 4,000 lb total. How is each pallet configured? Each bagged pallet contains forty 50 lb (22.68 kg) bags for a total net weight of 2,000 lb, or approximately 907 kg. Is Select 450 available in supersacks? Yes. A 2,000 lb supersack is available by request, subject to current supplier availability. Contact Sorbents Direct for pricing and freight. Are the technical values on this page manufacturer verified? The displayed reference values were retained from previously supplied product information, but Sorbents Direct has not yet confirmed them against a current publicly available Oil-Dri Select 450 TDS or lot-specific COA. Request current documentation before qualification or process design. Is freight included in the pallet price? No. Freight is separate and may be calculated at checkout using live LTL rates. Available options may include liftgate service and delivery appointments. What documentation is available? Sorbents Direct can request the current SDS, technical product information, and lot documentation from the supplier or manufacturer. Availability should be confirmed before purchase when documentation is required.
