摘要:
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.

摘要:
Disclosed herein is a catalyst for producing biodiesel, including a carrier having water resistance and an active component supported on the carrier and used in a hydrotreating reaction or a decarboxylation reaction. Since the catalyst for producing biodiesel includes a carrier having strong water resistance, the deactivation of the catalyst due to the water produced through a process of producing HBD can be prevented, thus remarkably improving the long term stability of a catalyst.

Disclosed is a catalyst including metal phosphide for preparation of biodiesel, and a method of preparing biodiesel from feedstock comprising vegetable oil through hydrotreating using the catalyst. When the catalyst including metal phosphide is used as a catalyst for preparation of biodiesel, preparation activity of hydrotreated biodiesel is high even without continuous supply of sulfiding agent, and hydrotreating and isomerization reactions occur at the same time, thus obtaining high-quality hydrotreated biodiesel having a low pour point.
摘要:
Disclosed is a method for producing a nitrile rubber comprising adding 0.1 to 5 parts by weight of at least one phosphate emulsifier selected from the group consisting of monoalkyl ether phosphate (MAP) represented by the following Formula 1 and dialkyl ether phosphate (DAP) represented by the following Formula 2, with respect to 100 parts by weight of monomers constituting the nitrile rubber. The method minimizes mold contamination during molding of produced nitrile rubber, eliminates the necessity of any process of removing mold contaminants, improves production efficiency and thus reduces defect rates of final molded articles.
