Import Biodiesel Purification Bc800 — Buy in Bulk from Supplier in China

The BC800 is a macroporous styrene-divinylbenzene (DVB) copolymer ion exchange resin engineered for the purification and refinement of crude biodiesel. Its polymer matrix features a hydrogen screen size distribution of 16 to 30 +16 mesh, enabling selective adsorption of free glycerides, soaps, and polar impurities from fatty acid methyl ester (FAME) streams. The crosslinked styrene-DVB structure delivers thermal and chemical stability under the alkaline conditions common in transesterification processes. The 16-30 mesh fraction corresponds to particle diameters of approximately 0.6 to 1.2 mm, a standard sizing for fixed-bed column operations in fuel upgrading. This resin functions primarily through ion exchange and adsorption mechanisms rather than catalysis, stripping contaminants that degrade cold-filter plugging point (CFPP) and oxidation stability.

The BC800's polymer backbone resists swelling in non-polar organic media, maintaining bed integrity across repeated regeneration cycles with methanol or aqueous brine. Typical operating temperatures for such purification resins range from 20°C to 80°C, though the supplier does not state explicit thermal limits. The macroporous architecture provides surface area and pore volume suited to high-molecular-weight contaminants like mono-, di-, and triglycerides. In biodiesel refining, removal of residual catalysts (sodium or potassium methoxide), soaps, and free fatty acids is critical to meet EN 14214 or ASTM D6751 specifications. The BC800 addresses these failure modes without the water washing steps that introduce emulsification risks and wastewater burdens.

Biodiesel manufacturers and fuel blenders purchase this resin for post-reactor polishing, particularly in plants processing multi-feedstock inputs with variable free fatty acid content. Laboratories and pilot-scale facilities employ it for method development in alternative fuel certification. The resin is supplied in bulk, typically in fibre drums or supersacks; the exact packaging and MOQ must be confirmed directly with Jiangsu Jinkai Resin Chemical. FOB and CIF Incoterms are mentioned in trade discussions, though specific pricing and lead times are not available in the listing data. Buyers should request a certificate of analysis (CoA) for each lot covering moisture content, total exchange capacity, and bead integrity.

Jiangsu Jinkai Resin Chemical Co., Ltd is located on Yuehai Road in the Coastal Industrial Park, Yancheng, Jiangsu Province, China (postal code 224500). The supplier holds an imported tier classification and a harbor trust tier, indicating marketplace registration without extensive verification documentation. The response rate is recorded at 0.00% with an average response time of zero hours, which suggests either no inquiry history or a data recording gap rather than operational inactivity. No factory audit, ISO certification, or export licence details are provided in the profile. The company specialises in ion exchange resins for industrial applications, with the BC800 positioned within its biodiesel and biofuel refining portfolio.

The listing does not disclose annual production capacity, number of employees, revenue figures, or named clients. No information is given about research and development facilities, patent holdings, or participation in industry consortia. The supplier's address places it within a coastal chemical industrial zone, which implies access to port infrastructure for export logistics, though this is not explicitly confirmed. Buyers should conduct independent due diligence, including verification of business licence, environmental compliance records, and product-specific test reports, before committing to orders. Direct communication through formal channels is essential given the absence of response statistics.
