Help: The use of dimethyl carbonate in oil formulation

2011-02-25View Original

Thread Content

I’m new to this industry. I’ve heard that dimethyl carbonate can replace MTBE and that it helps improve the quality of fuels, but it seems to be used very little in practice. I don’t understand what the reason is Another question: can dimethyl carbonate be added to both gasoline and diesel, or can it only be added to gasoline? I hope the seniors will kindly provide answers! Thank you!

From some information found online, it seems that DMC has great potential. I would also appreciate it if the senior could explain what the actual situation is. Thank you again! “Dimethyl carbonate (DMC) is the most prominent one, regarded as the most promising octane booster. Furthermore, studies have shown that the addition of DMC has little effect on the saturated vapor pressure freezing point and water solubility of gasoline. Compared to MTBE, DMC has a higher oxygen content. To achieve the same oxygen content in gasoline, the volume of DMC required is only about 40% of that needed for MTBE. It has a similar blending effect on catalyzed gasoline, but for straight-run gasoline, DMC is less sensitive than MTBE. When the addition volumes were classified as 3% DMC and MTBE, the baseline octane numbers of straight-run gasoline increased from 51.0 to 52.5 and 53.1 respectively; this shows that DMC is more suitable for blending gasoline with a baseline octane number greater than 80. ”

It is said that Haike has already begun limited-scale practical deployment; the specific details are unknown. **There are also no relevant policies.

Additionally, Sinopec prohibits the use of dimethyl esters; if they are detected, the product won’t pass inspection. Of course, money can get things done. . Hehe, you get it. . .

This technology is already widely used abroad, but not in China due to oil monopolies. DMC is primarily produced by companies other than Sinopec, whereas MTBE comes from Sinopec’s own refinery waste gases; the reason for this is self-evident. It will take at least another 5 years before this technology can be applied in this industry; as prices and costs decrease, it will also become a large market in the solvent industry

DMC’s capacity expansion will continue in the future; it seems that the new DMC units are also equipped with downstream PC facilities. It should still be a product with supply exceeding demand. It seems that the main downstream sector for DMC at present is still the coatings and adhesives industry? What percentage of the oil used is estimated to come from the upper floor? In which industries will the growth in demand for DMCs be primarily seen in the future?

Could you provide more details on its use abroad?

Dimethyl carbonate is widely used in oil modification; those who are interested can discuss this further. I am a manufacturer of dimethyl carbonate, and of course we also have the formulas for oil modification. QQ: 347068039
