从China供应商批发进口3-Lobe Alumina Catalyst Carrier — FOB条款

The 3-lobe alumina catalyst carrier from Zibo Highlion New Material is a shaped ceramic support designed for catalytic processes where geometric surface area and pressure-drop characteristics are critical. The trilobal extrusion profile increases external geometric surface area compared to cylindrical carriers of equivalent diameter, improving catalyst active-phase dispersion and reactant contact efficiency. The supplier states that all indexes, including size, pore structure, and stacking density, are adjustable according to buyer requirements, indicating a custom-manufacturing capability rather than fixed-catalogue stock. High compressive strength and low abrasion loss are claimed as base characteristics, essential for fixed-bed reactor applications where attrition generates fines that increase pressure drop and shorten run lengths.

Alumina catalyst carriers are typically produced from boehmite or pseudo-boehmite alumina precursors through extrusion, drying, and calcination at 500-900 °C, with phase composition ranging from gamma-alumina to delta/theta mixtures depending on calcination temperature. The 3-lobe geometry is standard in hydroprocessing, specifically hydrodesulfurisation (HDS) and hydrodenitrogenation (HDN) catalyst supports, as well as for CO shift catalyst carriers in ammonia and hydrogen plants. Pore volume for such carriers typically falls between 0.35-0.65 cm³/g, with surface areas of 150-300 m²/g for gamma-phase material, though Zibo Highlion's exact specifications require direct confirmation. The lobed shape also improves bed void fraction and reduces channeling compared to spheres or cylinders.

Primary buyers include petroleum refinery catalyst packagers, petrochemical hydrogenation unit operators, and syngas plant engineering contractors. The carrier itself is inactive; it is impregnated with active metal phases (typically Mo, Co, Ni, W) by catalyst producers before sale to end users. Zibo Highlion's location in Zibo, Shandong Province, places it within China's dense ceramic and refractory materials cluster, with access to bauxite-derived alumina feedstock. Buyers should confirm whether the supplier provides the carrier in calcined-only form or offers pre-impregnation services, and whether technical datasheets include crush strength values (typically measured in N/cm or N/mm for extrudates),attrition loss (ASTM D4058 or similar), and mercury porosimetry or nitrogen sorption pore distribution data.

Zibo Highlion New Material Co., Ltd. is located at No. 165, Xincun West Road, Zhangdian District, Zibo City, Shandong Province, 255000, China. Zibo is a major industrial centre for alumina-based ceramics and refractories, with raw material and technical infrastructure advantages for catalyst carrier production. The company holds harbor trust tier status, indicating baseline verification. The 0.00% response rate and zero average response hours recorded on the platform suggest no recent quotation activity, or that metrics are not being synchronised. Buyers should contact the company directly through its registered address to establish sales channel responsiveness and technical support availability.

The supplier profile does not disclose establishment date, production capacity, number of employees, annual turnover, specific certifications, or named clients. Its product focus is on customisable alumina carriers rather than standard-catalogue items, which implies extrusion and calcination capabilities with formulation flexibility. No ISO 9001, ISO 14001, or petrochemical industry qualification (such as supplier approval by major catalyst companies) is mentioned in the source data. Buyers should conduct due diligence including factory audit, quality system certification verification, and sample evaluation before committing to volume supply agreements for critical-path refinery catalyst projects.
