摘要:
The present invention relates to a method for joint production of low octane gasoline and high octane gasoline. In the process of oil or light oil rectification, the extraction points of the distillates therein are finely divided, and the temperature ranges for extraction of fractions are narrowed down. Each of the low and high octane components having a high content in the range from C6-C12 (which may be extended to C5-C14 where necessary) is then separately extracted. After that, low octane components are combined into compression ignition low octane gasoline products, while high octane components are combined into high octane gasoline products. The remaining fractions are respectively added as supplementing agents into the low octane gasoline products or high octane gasoline products dependent on their octane ratings. Low octane gasoline is used in compression ignition gasoline engines, while high octane gasoline is used in spark ignition gasoline engines.
摘要:
A gasoline product containing a combustion improver and a manufacturing method therefor. A combustion improver is added to gasoline to reduce an ignition point of the gasoline, so that the gasoline product can be applied to a compression ignition engine. Content of the combustion improver is controlled according to a value of octane in base gasoline, so as to implement homogeneity of a nitrogen oxygen equivalent contained in the gasoline product. The combustion improver is selected from at least one of ammonium nitrate and a derivative thereof, nitric acid ester and a derivative thereof, aniline and a derivative thereof, and nitrobenzene and a derivative thereof.
摘要:
A gasoline product for diffusion combustion compression ignition internal combustion engine, wherein the compression ratio of the internal combustion engine is generally 8-22; and the main component of the gasoline product is a mixture of hydrocarbons containing each of C6-C11, which is the same or similar to currently regular gasoline; wherein the gasoline product has a research octane number of 0-58.7.
摘要:
A compression-ignition low octane gasoline engine. The engine uses low octane gasoline and a compression-ignition method, does not require a spark plug, and compared with ordinary gasoline engines, increases thermal efficiency by approximately 40% and reduces green-house effects caused by emissions by approximately 45%. The "compression-ignition" of the low octane gasoline engine is a diffusion charge compression-ignition, differing from a homogeneous charge compression-ignition. The compression ratio in a cylinder can be 14 to 22, while an ordinary gasoline engine has a compression ratio of 7 to 11. The low octane gasoline engine has a simple structure, easy combustion control, a low noise level, and a low failure rate. As the low octane gasoline can be free of aromatic hydrocarbons, and not require the addition of antiknock agents such as MTBE and MMT, the present novel gasoline engine is a highly efficient, clean, and environmentally friendly internal combustion engine.

A clean, high efficient and environmentally friendly gasoline product with main fractions of C6-C11 has a low octane rating and a low spontaneous ignition temperature. It can be compressively ignited within an internal combustion engine with a compression ratio of 16-19. Small amount of ethanol or dimethyl ether can be added into the gasoline product.

摘要:
A new method is disclosed for producing purified terephthalic acid (PTA) by keeping terephthalic acid (TA) in dissolved state during the process of oxidation reaction, thereby, the obtained intermediate product crude terephthalic acid (CTA) do not contain the two impurities of 4-carboxyl benzaldehyde (4-CBA) and P-methyl benzoic acid (PT acid), so that it can leave out the "purified" production process, and reduce the consumptions of raw material, acetic acid, fuel and power, and water to save the production cost.
