This invention relates to a method of producing aromatic hydrocarbons and olefin from hydrocarbonaceous oils including large amounts of polycyclic aromatic compounds having two or more rings via partial hydrogenation in the presence of a hydrogenation catalyst and catalytic cracking in the presence of a catalytic cracking catalyst.

Method of producing aromatic hydrocarbons and olefin from hydrocarbonaceous oils comprising large amounts of polycyclic aromatic compounds

Provided is a method for reducing the amount of organic acids in a hydrocarbon oil fraction by hydrogenating the organic acids in the hydrocarbon oil fraction under mild conditions. Provided is a new method able to overcome the problem of organic-acid-induced corrosion during the process of distillation, by using hydrogen or a hydrogen-containing mixed gas and a hydrogenation catalyst to subject the organic acids in the hydrocarbon oil fraction to hydrogenation at an appropriate temperature and pressure, thereby converting the same to hydrocarbons and so reducing the amount of organic acids in the hydrocarbon oil fraction.

Method for reducing the amount of organic acids in a hydrocarbon oil fraction

The present invention relates to a method for manufacturing aromatic products (benzene/toluene/xylene) and olefinic products from an aromatic-compound-containing oil fraction, whereby it is possible to substitute naphtha as a feedstock for aromatic production and so make stable supply and demand, and it is possible to substantially increase the yield of high-added-value olefinic and high-added-value aromatic components, by providing a method for manufacturing olefinic and aromatic products from light cycle oil comprising a hydrogen-processing reaction step, a catalytic cracking step, an separation step and a transalkylation step, and optionally also comprising a recirculation step.

Method for producing high-added-value aromatic products and olefinic products from an aromatic-compound-containing oil fraction

This invention relates to a method of producing aromatics and olefins from oils derived from coal or wood, including partially saturating and cracking the oils derived from coal or wood in a hydrogenation and reaction area, separating them depending on the number of carbons, recirculating heavy oils having 11 or more carbons to the hydrogenation and reaction area, feeding oils suitable for producing BTX to an aromatic separation process and a transalkylation process to recover aromatics, and feeding hydrocarbonaceous components having 5 or less carbons to a light separation process, thus obtaining olefins.

Method of producing valuable aromatics and olefins from hydrocarbonaceous oils derived from coal or wood

This invention relates to a petroleum refining method for producing high value-added clean petroleum products and aromatics (Benzene/Toluene/Xylene) together, by which low pollution petroleum products including liquefied petroleum gas or low-sulfur gas oil and aromatics can be efficiently produced together from a fluid catalytic cracked oil fraction.

Process for the preparation of clean fuel and aromatics from hydrocarbon mixtures catalytic cracked on fluid bed

The present invention relates to a method of producing aromatic products (benzene/toluene/xylene) and olefin products from petroleum fractions obtained by fluid catalytic cracking, and, more particularly, to a method of producing products comprising high-concentration aromatic products and high value-added light olefin products from light cycle oil obtained by fluid catalytic cracking.

Method for producing high value aromatics and olefin from light cycle oil produced by a fluidized catalytic cracking process
