Product Description:

1. Product Introduction & Core Advantages

Aogochem's Y-Type Zeolite Catalyst is the foundational and most widely used cracking catalyst in the global refining industry. Characterized by its FAU framework with a three-dimensional network of large supercages accessible through 7.4 Å pores, it provides unparalleled access for bulky hydrocarbon molecules. Its strong acidity and exceptional ion-exchange capacity make it the active heart of catalysts for converting heavy oil into valuable fuels and petrochemicals.

As the primary active component in Fluid Catalytic Cracking (FCC) catalysts, Y-Zeolite is responsible for breaking down heavy gas oils into gasoline, diesel, and light olefins. It is equally crucial in hydrocracking catalysts for producing high-quality middle distillates. For refineries in the MENA and CIS regions, which process heavy and complex crudes, advanced Y-Type zeolites are essential for maximizing liquid yield, operational flexibility, and overall refinery profitability.

We supply various Y-Zeolite grades, including high-stability Ultra-Stable Y (USY) and rare-earth exchanged forms, tailored for specific process goals. Its hydrothermal stability is engineered to withstand regenerator conditions. Partnering with Aogochem provides access to consistent, high-performance Y-Zeolite, deep refining process expertise, and a supply chain dedicated to supporting the complex needs of refineries in strategic energy markets.

2. Technical Specifications & Performance Data

Y-Type zeolite's properties are tailored for severe refining operations. Aogochem offers a range of formulations.

Parameter	Unit	Typical Specification / Description	Importance / Notes
Framework Type	-	FAU	Defines the 3D large-pore (7.4 x 7.4 Å) structure with supercages (~12 Å diameter), essential for cracking large molecules.
Key Variants	-	NaY, USY (Ultra-Stable Y), REY (Rare-Earth Y)	USY offers higher hydrothermal stability and lower hydrogen transfer; REY provides higher activity and gasoline selectivity.
SiO₂/Al₂O₃ Molar Ratio	-	5:1 (NaY) to >100:1 (High-Silica USY)	Higher ratios (in USY) dramatically improve stability by dealumination, crucial for FCC regenerator resistance.
Unit Cell Size (UCS)	Å	~24.25 - 24.70	A critical measure of framework aluminum content and acid site density, directly related to catalytic activity and selectivity.
Specific Surface Area (BET)	m²/g	600 - 900	Very high surface area provides a vast number of active sites for hydrocarbon cracking.
Primary Acid Sites	-	Brønsted and Lewis	Generated from framework aluminum. The ratio influences product selectivity (e.g., gasoline vs. light gases).
Thermal & Hydrothermal Stability	-	Excellent (especially USY)	Engineered to retain crystallinity and activity at temperatures exceeding 800°C in steam-rich FCC regenerator environments.

3. Primary Application Industries

Y-Type zeolite is indispensable in core conversion processes that determine a refinery's output and economics.

Fluid Catalytic Cracking (FCC): The dominant application. As the active component in FCC catalysts, Y-Zeolite (especially USY and REY) cracks heavy vacuum gas oil and residues into lighter products. It is fundamental to gasoline production and a major source of propylene and other light olefins. Catalyst formulations are fine-tuned to maximize desired product slates.
Hydrocracking: Y-Zeolite serves as the acidic component in bifunctional hydrocracking catalysts. Paired with a hydrogenation metal (e.g., Pt, Pd, Ni-Mo, Ni-W), it cracks pre-hydrotreated feedstocks under high hydrogen pressure to maximize yields of high-quality diesel, jet fuel, and naphtha, with excellent product properties.
Other Processes: Also used in alkylation, isomerization, and as a versatile adsorbent and catalyst support in petrochemical applications due to its large pore size and acidity.

5. Handling & Operational Guidelines

Integration into Catalyst: Y-Zeolite is typically supplied to catalyst manufacturers who incorporate it into finished FCC or hydrocracking catalyst particles. Handling at the zeolite production stage is highly controlled.
In-Use Operation (in FCC): In the FCC unit, the catalyst containing Y-Zeolite cycles between the reactor (cracking at ~500-550°C) and regenerator (coke burn-off at ~700°C+). Proper control of regenerator temperature and oxygen content is vital to preserve zeolite stability.
In-Use Operation (in Hydrocracking): In hydrocracking units, the catalyst operates in a fixed-bed reactor under high hydrogen pressure. Careful presulfiding and control of feed nitrogen levels are critical to protect the catalyst's acid and metal functions.
Storage & Safety (Zeolite Powder): Store in a dry, sealed environment. As a fine powder, use appropriate dust control measures and PPE (respirator, gloves, safety glasses) during handling to prevent inhalation or contact. Refer to the Safety Data Sheet (SDS).
