The invention relates to a polypropylene based nucleating agent masterbatch and a preparation method thereof. The masterbatch is composed of, by weight, 0.1 to 60 wt. % of bis-2-hydroxyethylene terephthalate (BHETA) based nucleating agent, 40 to 99.9 wt. % parts of polypropylene. The present invention discloses a process for preparation of a polypropylene masterbatch by mixing polypropylene with a nucleating agent as represented in FIG. According to the invention, the prepared polypropylene masterbatch has the advantages of being a masterbatch which can be added in any grade of polypropylene, does not cause inhalation hazards while handling, is easy to handle and has improved dispersion in the base polypropylene.

The present disclosure provides a process for preparing a reforming catalyst, said process comprising: (a) impregnating at least one support with at least one promoter metal and at least one active metallic component to obtain a second catalytic precursor; (b) contacting the second catalytic precursor with at least one non-metallic component to obtain a third catalytic precursor; (c) coating the third catalytic precursor with at least one silanizing agent to obtain a coated third catalytic precursor; and (d) drying the coated third catalytic precursor to obtain a dried third catalytic precursor followed by calcination of the dried third catalytic precursor to obtain the reforming catalyst. The present disclosure also provides a reforming catalyst and the process for catalytically reforming a hydrocarbon feed stream by using the reforming catalyst.

Reforming catalyst and a method of modification and application thereof

A process for oligomerization of olefins includes contacting a feedstock with a zeolite catalyst under conditions of oligomerization at pressure between 8-20 bars and temperature in the range of 60-100&#xb0; C. to obtain oligomers, wherein, the zeolite catalyst has a pentagonal sheet morphology.
