MTA process
Thread Content
I’m not sure what MTA is – it seems to be a process for producing some organic products using methanol. Could someone please explain it to me?
Methanol to aromatics is a large-scale downstream conversion technology for methanol, with BTX (benzene, toluene, xylene) as the main target products. Using MoHZSM-5 (ion-exchange) molecular sieve as a catalyst and methanol as the feedstock, under conditions of T = 380–420°C, atmospheric pressure, and LHSV = 1 h-1, the methanol conversion rate exceeds 99%, the selectivity of the liquid-phase products is greater than 33% (on a mass basis of methanol), while the selectivity of the gas-phase products is less than 10%. The aromatic content in the liquid-phase product is greater than 60%. The laboratory catalyst screening and evaluation as well as repeated regeneration tests have been completed; the single-pass lifetime of the catalyst is greater than 20 days, with an estimated total lifetime of over 8,000 hours.
