Hey everyone, what catalysts are used in MTBE production at various factories? Let’s share our experiences
Regarding the catalysts for MTBE plants! http://bbs.hcbbs.com/thread-250592-1-1.html
This was found online: Catalyst resin specific for MTBE (D006-III). Product overview for catalyst resin specific for MTBE (D006-III): The catalyst resin D006-III is used for methyl butyl ether (MTBE), which is an excellent component in the formulation of lead-free gasoline, as well as a raw material for producing high-purity isobutylene. It is formed by the enol condensation of isobutylene in the carbon composition with methanol under the action of a catalyst. Large-pore strong acid cation exchange resins are excellent catalysts, and they are the only catalysts that offer high activity, high conversion rates, and high selectivity. The D006-III large-pore highly acidic cation exchange resin catalyst, developed by our factory’s technical staff with the strong support of higher education institutions, features high activity at low temperatures; it can initiate catalytic reactions at 27 degrees Celsius, with 94% of its active components remaining functional at 40 degrees Celsius. It can withstand high temperatures up to 130 degrees Celsius, does not cause desulfurization, achieves a conversion rate of up to 98%, and a selectivity of 100%. Catalysts with such high performance are second to none in China. Product Features » Brand: New Era. Product Model: D006-III. Product Specifications: φ0.315-1.250mm
I am using the D005-II resin catalyst from Dandong Mingzhu Special Resins Co., Ltd. Here are the recommended operating conditions for this catalyst: 1. Alcohol-to-olefin ratio (in mmol ratio): 0.98–1.05:1. 2. Reaction temperature: 50–80°C; the optimal temperature is 55–65°C. 3. Space velocity: 1–5 h-1; the optimal space velocity is 1.5–2.5 h-1. 4. Maximum pressure drop: ≤0.1 MPa. 5. MTBE yield (per ton of dry catalyst): For FCC tetrahydrocarbons, it is 4500–6000 tons or more; for DCC tetrahydrocarbons, it is 8000–10000 tons or more. 6. Isobutylene conversion rate in the reactor: For FCC tetrahydrocarbons, it is ≥92%; for DCC tetrahydrocarbons, it is ≥95%. 7. Isobutylene conversion rate in the catalytic distillation column: ≥99%. Thank you!
