The creation of activated carbon from walnut shells is a sophisticated blend of thermal engineering and chemical ingenuity, transforming rigid, fibrous shells into a labyrinth of pores capable of trapping contaminants at the molecular level. Walnut shells, composed primarily of lignin (40-50%) and cellulose (20-30%), offer a carbon-rich base with inherent durability, yielding a material that withstands high-pressure environments better than softer precursors like wood.

1. Feedstock Sourcing and Initial Processing

It starts with selecting high-quality walnut shells from Juglans regia trees, prized for their thick, oil-resistant exteriors that minimize cracking during handling. In Iran's walnut belt, we process over 200,000 tons of shells yearly, grinding them into 2-10 mm granules via impact crushers to optimize surface exposure. A preliminary hydrothermal treatment—steaming at 120-140°C for 30-45 minutes—pre-swells the fibers, increasing carbonization yield by 12-18% while extracting tannins that could otherwise reduce porosity.

2. Thermal Carbonization: Forming the Core Structure

Carbonization occurs in vertical retorts or horizontal kilns at 500-700°C under vacuum or helium to prevent combustion. This devolatilization phase expels 50-60% of the shell's mass as syngas and tars, leaving a robust char with 65-75% fixed carbon. Duration varies: 2-4 hours for batch systems, ensuring uniform heating to avoid hotspots that degrade structure. Our facilities integrate heat recovery from exhaust gases, cutting energy consumption by 25% and aligning with green manufacturing goals.

3. Activation Strategies: Engineering Porosity for Peak Performance

Activation elevates the char from inert to active, creating a surface area of 900-1,400 m²/g through controlled etching.

Steam and Gas Activation: The most common for walnut shells, involving superheated steam at 850-950°C in fluidized beds. This generates a pore distribution skewed toward micropores (70-80% <1 nm), perfect for gases and small organics, with apparent density of 0.45-0.55 g/cm³. CO₂ activation at 900°C for 90 minutes achieves iodine adsorption of 1,050-1,250 mg/g, as the gas reacts via the Boudouard equilibrium (C + CO₂ → 2CO), selectively widening channels without over-etching.

Advanced Chemical Methods: Using phosphoric acid (H₃PO₄) at 400-500°C, we impregnate the char at a 1

ratio, followed by carbonization. This yields hierarchical pores (micro + macro) with methylene blue uptake of 400-500 mg/g, superior for dyes and pharmaceuticals. Post-activation, a multi-stage wash (H₃PO₄ neutralization with NaHCO₃) removes residues, achieving ash content below 1%. Unlike aggressive KOH, phosphoric acid preserves the shell's phenolic groups, boosting metal ion affinity (e.g., 92% Pb²⁺ removal).

Imagine a filtration material that's not only powerful but also kind to the planet and your wallet. Walnut shell activated carbon delivers exactly that, outperforming traditional options like coal-based carbons in durability and value.
