The effects of nucleating/clarifying agents in polypropylene

Polypropylene (PP) is one of the most important polymers of our time, produced at the highest volumes all over the world. The converting techniques of its are very versatile, from extrusion through cast- and blown-film, blow moulding till injection moulding, so as to satisfy the demand of the different applications such as the building-trade, packaging, household articles, automotive industry, etc. Of course, for all applications the customers (converters) need more and more advanced properties that can make the converting process smoother, faster, cheaper and the final product better.

Function of geological study in Pakistan hydrocarbon research

As the subject of the Pakistan hydrocarbon project, there several exploring and producing wells have been drilled since 1999 by MOL Plc. and Partners. Geological study of the material of these drillings was mainly fulfilled by the geologist team of the Exploration and Production Division at Békásmegyer (HU). Our work is to examine the cuttings and core samples from petrographic and palaeontological point of view.

Alternative methods for evaluating exploration projects

Oil production practically is the realisation of the (extra) profit captured through exploration. Geological exploration secures the higher than average profitability for the upstream oil companies. Geological exploration is a highrisk high-reward operation.

Compliance with future regulation of air quality management in refining

Meeting the increasing demand for motor fuels parallel with the more and more stringent environmental norms can only be accomplished by improving engine design in parallel with the development of motor fuels. This continuously forces refineries to invest into technological development projects and this, in turn, unavoidably entails the increased emission of air pollutants from the refineries.

C9+ frakció elkeverésének lehetôségei a Dunai Finomítóban

As of January 1, 2008 maximum sulfur content of heating oils is 1000 mg/kg. With regard to this, I examined as an alternative the possibility of mixing the TVK produced C9+ fraction with heating oil in the Gasoil-mixing unit of Danube Refinery and it was clear that mixing these two materials would have several benefi ts.

FCC-benzinekben lévô egyedi olefinek átalakulásának vizsgálata a hidrogénezô kéntelenítés körülményei között

During heterogeneous catalytic desulphurization of FCC gasoline (full range or heavy FCC gasoline) many chemical reactions take place apart from the main reactions. Thus the hydrocarbon composition of the final product changes which significantly influences other important properties (e.g.: researchand motor octane number, storage stability etc.) of the product. In the paper conversion of individual olefins and its effect on the octane number was investigated in a laboratory scale reactor system.
