Abstract: A new process for the production of purified terephthalic acid (PTA) is disclosed to keep terephthalic acid (TA) in dissolved state during the process of oxidation reaction, to obtain intermediate product crude terephthalic acid (CTA) not containing the two impurities of 4-carboxyl benzaldehyde (4-CBA) and p-methyl benzoic acid (PT acid), so that it can eliminate the “purified” production process, and reduce the consumptions of raw materials, acetic acid, fuel and power, and water, thereby saving production costs.

Abstract: A method for achieving a hybrid combustion mode of an internal combustion engine, a controller thereof, and an internal combustion engine. The hybrid combustion mode of an internal combustion engine comprises: directly injecting fuel in a cylinder; using homogeneous charge compression ignition combustion mode when the internal combustion engine is run; and when the internal combustion engine is low in load, or when it cannot be determined, that a compression ignition condition is met, switching a combustion control mode from ignition to compression ignition, if a compression ignition state can be switched to smoothly, maintaining the compression ignition combustion mode, and if the compression ignition state cannot be switched to smoothly and therefore the rotation speed of the engine decreases abnormally, quickly recovering the ignition combustion control mode. Cool start of low-octane gasoline internal combustion engine in a low-temperature environment can be implemented.

Abstract: Disclosed is a process for producing purified terephthalic acid, which employs new para-xylene (PX) oxidation technology to make the intermediate product, crude terephthalic acid (CTA) produced by oxidation does not contain two purities of 4-carboxybenzaldehyde (4-CBA) and para-toluic acid (PT acid), so that the factory processing operation of “purification” can be omitted. PTA product produced by the present process is more suitable to be used as the polymer raw material of food packaging material, beverage bottle material, medicament packaging material and medical appliance since the content of formaldehyde group thereof is extremely low and it has the advantages of being safer and having no poison.
