This invention relates to a hydrogen spillover-based catalyst and use thereof, wherein a hydrogen activation metal cluster is dispersed in the form of being encapsulated in a crystalline or amorphous aluminosilicate matrix which is partially or fully structurally collapsed zeolite, thereby exhibiting high hydroprocessing or dehydrogenation activity and suppressed C&#x2014;C hydrogenolysis activity.

Catalyst containing metal cluster in structurally collapsed zeolite, and use thereof

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.

The present invention relates to a bifunctional catalyst for a hydrodewaxing process with improved isomerization selectivity, and to a method for manufacturing the same, and more particularly to a bifunctional catalyst and to a method for manufacturing same, which is characterized in that EU-2 zeolite with a controlled degree of phase transformation is used as a catalyst support having an acid site. The EU-2 zeolite, the degree of phase transformation of which is controlled, includes, by controlling synthesis parameters of EU-2, predetermined amounts of materials that are phase-transformed from EU-2 crystals such as cristobalite and quartz. The metal loaded bifunctional catalyst according to the present invention improves selectivity of the isomerization process, rather than a cracking reaction, during a hydroisomerization reaction of n-hexadecane. Therefore, the bifunctional catalyst can be widely used as a catalyst for a dewaxing process such as lubricant base oil and diesel oil.

Disclosed is a method of recovering 1,3-butadiene from a C4 stream containing butane, isobutane, 2-butene, 1-butene, isobutene, butadiene and acetylene. The process of recovering highly pure 1,3-butadiene includes acetylene conversion for selectively converting acetylene through liquid-phase hydrogenation, so that the acetylene content is decreased to 70 wt ppm or less, and 1,3-butadiene extraction using an extractive distillation column, a pre-separator, a solvent stripping column, a solvent recovery column, and a purification column. Through the acetylene conversion, the concentration of vinylacetylene is decreased to 70 wt ppm or less, after which 1,3-butadiene is recovered using only one extractive distillation column, thereby considerably decreasing the degree of utility and the loss of streams in the course of extraction. The number of units necessary for the process is decreased, thus remarkably reducing the time during which impurities can accumulate in a processing unit.

To synthesize the required catalyst, the important procedures are mixing ratio and mixing sequence of Mn, P, zeolite, and inorganic complex.
