Abstract: A process for improving fluidity of hydrocarbon fractions by dewaxing thereof is described. In the process, hydrocarbon fractions are contacted with hydrogen in the presence of a specific type of catalyst, thereby lowering the pour point of the hydrocarbon fraction. The catalyst comprises a specific type of zeolite which is defined by a specific X-ray diffraction pattern (such as that shown in Fig. 1) and which has a mesitylene adsorption not less than 1.8 wt%.

In the process, hydrocarbon fractions are contacted with hydrogen in the presence of a specific type of catalyst, thereby lowering a pour point of the hydrocarbon fraction. The catalyst comprises a specific type of zeolite which is defined by a specific X-ray diffraction pattern and which has a predetermined range of mesitylene adsorption.

Abstract: PURPOSE:To dewax efficiently a hydrocarbon fraction and to lower pour point, by bringing the hydrocarbon fraction in the presence of hydrogen into contact with a catalyst composed of a mixture of a mordenite type zeolite and a specified pentacil type zeolite. CONSTITUTION:A mordenite type zeolite is uniformly mixed with a pentacil type zeolite having an X-ray diffraction pattern (S being intense, VS being very intense, M being medium intense) shown in Table. The monovalent alkali metal ion of the resulting zeolite mixture powder is subjected to an ion exchange treatment with hydrogen ion or ammonium ion to thereby convert it into an acid type. Pref. further a binder such as alumina sol is added thereto and the mixture is shaped into a particle having the desired size, dried and calcined to obtain a catalyst. A hydrocarbon fraction such as gas oil or kerosene is brought into contact with the catalyst in the presence of hydrogen at 200-500 deg.C to dewax it.

Abstract: PURPOSE:To perform effective aromatization of a hydrocarbon fraction with a relatively low b.p. which contains paraffin or olefin, by bringing the hydrocarbon fraction into contact with a specified crystalline aluminosilicate-contg. catalyst in the presence of hydrogen. CONSTITUTION:A hydrocarbon fraction is brought into contact with a catalyst which contains a crystalline aluminosilicate in the presence of hydrogen. The aluminosilicate is obtained by inter-action of an aqueous mixt. of silica source, alumina source and carboxyl group-contg. org. compd. in SiO2/Al2O3, H2O/SiO2: OH /SiO2 and A/Al2O3 (where A is a carboxyl group-contg. org. compd.) molar ratios of 10-200, 0.01-1.0 and 0.05 or higher, respectively. The silica sources are silica sol, sodium silicate, etc. The alkali source, preferably caustic soda, is added in such an amt. that OH may be present in the system as specified above.

Abstract: PURPOSE:To dewax efficiently a hydrocarbon fraction and to lower pour point, by bringing the hydrocarbon fraction in the presence of hydrogen into contact with a catalyst mainly composed of a mordenite type zeolite contg. a platinum metallic component and having a specified composition. CONSTITUTION:An aq. reaction mixture contg. a silica source such as silicic acid, an alumina source such as aluminum sulfate, an alkali soure such as caustic soda and a platinum metal source such as chloroplatinic acid is preped. so as to give a composition within the range of SiO2/Al2O3=9-50, OH /SiO2=0.1- 0.5 (OH being alkali source), H2O/SiO2=10-50 and M/SiO2=1X10 -1X10 (M is platinum metal source) in a molar ratio. The mixture is then reacted at 140-200 deg.C to crystallize it, thus obtaining a catalyst mainly composed of a mordenite type zeolite contg. a platinum metallic component. A hydrocarbon fraction such as gas oil is brought into contact with the catalyst in the presence of hydrogen to dewax it.
