    摘要： A method for producing monocyclic aromatic hydrocarbons of 6 to 8 carbon number from a feedstock oil containing polycyclic aromatic hydrocarbons and saturated hydrocarbons and having a 10 volume % distillation temperature of at least 140°C and a 90 volume % distillation temperature of not more than 380°C, the method comprising a cracking and reforming reaction step of bringing the feedstock oil into contact with a monocyclic aromatic hydrocarbon production catalyst comprising a crystalline aluminosilicate to cyclize and dehydrogenate the saturated hydrocarbons and to partially hydrogenate the polycyclic aromatic hydrocarbons using a hydrogen transfer reaction from the saturated hydrocarbons, thereby obtaining a product comprising monocyclic aromatic hydrocarbons of 6 to 8 carbon number, a hydrogenation reaction step of hydrogenating a portion of the product obtained in the cracking and reforming reaction step, a refining and collection step of refining and collecting monocyclic aromatic hydrocarbons of 6 to 8 carbon number by distilling a hydrogenation reaction product obtained in the hydrogenation reaction step, a recycling step of returning a heavy fraction of 9 or more carbon number, which has been separated and removed from the monocyclic aromatic hydrocarbons of 6 to 8 carbon number in the refining and collection step, to the cracking and reforming reaction step, a hydrogen recovery step of recovering, from the product obtained in the cracking and reforming reaction step, hydrogen that is produced as a byproduct in the cracking and reforming reaction step, and a hydrogen supply step of supplying the hydrogen recovered in the hydrogen recovery step to the hydrogenation reaction step, wherein the monocyclic aromatic hydrocarbon production catalyst includes at least one of phosphorus, boron, gallium, and zinc, and supply of hydrogen from an external source is completely eliminated.

    摘要： The invention provides a process for preparing a hydrowax comprising the steps of: (a) providing a hydrocarbonaceous feedstock which contains more than 4% by weight of hydrocarbons boiling in the range of from 550 to 800 °C; (b) hydrotreating the hydrocarbonaceous feedstock with a hydrotreating catalyst in the presence of a hydrogen- containing gas under hydrotreating conditions to obtain a hydrotreated product; (c) hydrocracking at least part of the hydrotreated product as obtained in step (b) with a hydrocracking catalyst in the presence of a hydrogen-containing gas under hydrocracking conditions to obtain a hydrocracked product, which hydrocracking catalyst contains a zeolitic component which is present in an amount of at least 14 wt%, based on the total weight of the hydrocracking catalyst, and wherein the volume ratio of the hydrotreating catalyst as used in step (b) and the hydrocracking catalyst is more than 1; and (d) recovering from the hydrocracked product as obtained in step (c) the hydrowax.
