Which has higher diene selectivity, the UOP catalyst or the DMTO catalyst?

Personally, I think UOP is better:lol:lol
The domestic version has a high efficiency; UOP incorporates OCP technology, which results in a high overall olefin yield
Then why are UOP’s catalysts so expensive! Is it just because of the low wear? ?
UOP performs better than DMTO in terms of olefin conversion rate and catalyst loss, and as far as I know, UOP’s catalysts are even a bit cheaper than those available in China.
The catalyst strength is indeed better with UOP, but UOP’s olefin selectivity isn’t as high as that of DMTO, right? I think it used to be DMTO at 200,000, and UOP at 220,000 to 240,000 per ton.
For MTO, it should not be referred to as \"olefin conversion rate\"; rather, it should be the methanol conversion rate, along with the yield and selectivity of olefins. The conversion rate of methanol in UOPMTO is lower than that in DMTO. At the same scale (based on methanol as the feedstock), the UOP MTO catalyst requires less loading, resulting in less catalyst loss. The unit price of UOP catalysts is higher than that of DMTO catalysts, but the annual catalyst consumption cost is lower than that of DMTO.
I’ve been reading a lot of relevant materials recently. Upon calculation, the catalyst consumption cost over a year is indeed the same for both types of olefins; the cost for the UOP process is significantly lower than that of DMTO. But why is it always said online that the catalysts for DMTO are much cheaper compared to those used abroad, costing only 8–15% of the price of foreign catalysts? Can’t understand. Moreover, many data show that UOP offers higher efficiency in terms of methanol conversion rate, olefin conversion rate, catalyst consumption, and investment costs compared to DMTO and DMTO-II. Why is DMTO used so much domestically while UOP is used less?
Personally, I think UOP is better; the prices of their catalysts are similar to those of the other company’s
