摘要： The object of the invention is a method for producing naphthenic process oils that have a high content of naphthenic carbon atoms of 20-60 wt % and a low content of polycyclic aromatics of less than 3 wt %, determined in accordance with IP 346, by the hydrogenation of a process oil educt that has a high content of polycyclic aromatics. The method in accordance with the invention enables secondary extracts, such as are formed in the production of label-free process oils, even in a mixture with primary extracts, to be utilized in an economically meaningful way. The resulting process oils are likewise label-free, so that the use of PCA-containing process oils can be reduced and less of these substances will get into the environment. Through this the environment and in particular health are less stressed. In addition, the starting substances in this way can lead to a different use and no longer have to be added to heating oil. By avoiding heating oil, CO2 emissions are also reduced. Also, through the direct hydrogenation of DAE, high value naphthenic process oils are obtained by the method in accordance with the invention. The process oils that are obtained contain surprisingly high amounts of naphthenic hydrocarbon compounds. In addition, an object of the invention is the use of the process oils produced in accordance with the invention as a plasticizer or extender oil for natural and synthetic rubber mixtures or thermoplastic elastomers.

摘要： Systems and methods are provided for producing an improved product slate during hydrocracking of a feedstock for production of naphtha and distillate fuels. The methods can include use of stacked beds and/or sequential reactors so that a feedstock is exposed to a suitable catalyst under aromatic saturation conditions prior to exposing the feedstock to the hydrocracking catalyst. The catalyst for performing the aromatic saturation process can be a catalyst including a Group VIII noble metal, such as Pt, Pd, or a combination thereof, while the hydrocracking catalyst can include Group VIB and Group VIII non-noble metals.

摘要： A process that provides for the improvement of the properties of a distillate feedstock that has significant concentrations of nitrogen and polyaromatic compounds. The process includes a first reaction zone that uses a base metal catalyst and is operated under high pressure conditions to provide for the hydrodenitrogenation of organic nitrogen and saturation of polyaromatic compounds contained in the distillate feedstock. The first reaction zone treated effluent is separated into a heavy fraction and a lighter fraction with the heavy fraction being charged to a second reaction zone that also uses a base metal catalyst and is operated under high pressure conditions to provide for the saturation of monaromatic compounds that are contained in the heavy fraction. The inventive process provides for a high quality, low-sulfur and low-nitrogen diesel product that has a significantly lower aromatics content than the distillate feedstock and having a high value for its high Cetane Index.
