{"product_id":"ekmfbrnat","title":"ECS-KM Fixed Bed Reactor (Max. 1000°C, 0.5 MPa) with Nickel-Based Alloy Tube for Polymer Upgrading, EKMFBRNAT","description":"\u003cp\u003eUsing a fixed-bed reactor with a nickel-based alloy tube (such as Inconel 600, 625, 718, or Hastelloy C-276) is standard practice for high-temperature, high-pressure catalytic upgrading of polymer waste and biomass feedstocks. Standard 316 stainless steel degrades rapidly under harsh thermo-chemical conditions—such as supercritical water gasification, hydrothermal liquefaction (HTL) upgrading, or halide-containing polymer depolymerization—due to pitting, stress corrosion cracking (SCC), and hydrogen embrittlement.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCorrosion Mechanisms in Polymer Processing\u003c\/strong\u003e: (1) \u003cstrong\u003eHalide Attack (HCl, HF)\u003c\/strong\u003e: Dechlorination of PVC or halogenated plastic waste generates gaseous HCl. Molybdenum-rich alloys like Hastelloy C-276 form protective oxide\/molybdate films that mitigate severe pitting. (2) \u003cstrong\u003eCarburization \u0026amp; Metal Dusting\u003c\/strong\u003e: High carbon activity from cracked polyolefins (PE, PP, PS) at 500-800 °C can diffuse carbon into the tube wall, forming brittle internal chromium carbides. High-nickel matrices inhibit carbon diffusion. (3) \u003cstrong\u003eOrganic Acids \u0026amp; Phenols\u003c\/strong\u003e: Biomass fast-pyrolysis vapors contain high concentrations of acetic acid, formic acid, and phenolic compounds. High chromium content (like in Inconel 625) provides long-term passivation against organic acid corrosion.\u003c\/p\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cul\u003e\n\u003cli\u003eEKMFBRNAT (EKM-FBR-NAT)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003ePower\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cul\u003e\n\u003cli\u003eAC220V±10%, single phase, 50\/60Hz, 3000 W \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003eWorkflow Design \u0026amp; General Description\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cul\u003e\n\u003cli\u003eStock Feeding System: 2 gas lines and 1 liquid line (gasification)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGas line\u003c\/strong\u003e: two-lines gases go through the second-state relief valve, filter, and enter into the vaporization mixer under MFC control.
