The quality and performance of coal-to-oil products
Thread Content
This post was last edited by jordan569 on 2013-1-6 22:45. After using coal to produce oil, can the quality of such oil products be compared to that of petroleum-based products? Will there be issues of incompatibility when using it on various engines? Are there any reports and results on the trial use of coal-derived oil products? Which domestic organization is currently working on this task? Shall we discuss it together? I just thought of this question. . Note $ # , $ $
There is probably some difference, but it shouldn’t be a big issue. I think the main problem is that the octane rating of gasoline and the cetane rating of diesel may not meet the required standards; as for other parameters, I believe there won’t be much difference after hydrogenation.
There must be a difference; just as mentioned above, the octane rating varies, and the heavy components contained within also differ.
After refinement, the difference should not be significant; after all, if it is to be sold on the market, it must meet **standards**. However, there is a significant difference between crude oil and rough oil, and the refining processes and conditions also vary greatly
After refinement, it should meet the national standards for gasoline and diesel; the content of heteroatoms should be low
In coal-to-oil plants, aside from the differences in coal liquefaction units compared to conventional oil refineries, the other units are similar to those in oil refineries. The products produced must pass inspections in accordance with **standards before they can be released for sale; therefore, there is not much difference between these products and those from traditional refining companies, with only minor differences that do not affect the performance of the products.
The liquefied crude oil produced by the direct coal liquefaction process retains some of the properties of the coal used as raw material for liquefaction; it has a high aromatic content, high levels of nitrogen and oxygen heteroatoms, and poor color and storage stability. To achieve a quality similar to that of petroleum products, upgrading processing is necessary.
