Integrated process for the preparation of olefins
The invention provides a process for preparing olefins, comprising: (a) reacting an oxygenate and/or olefinic feed in a first reactor in the presence of a molecular sieve catalyst to form a first effluent comprising olefins; (b) fractionating at least part of the first effluent into an olefinic product fraction comprising ethylene and propylene and an olefinic product fraction comprising olefins containing 4 or more carbon atoms; (c) subjecting a paraffin-containing hydrocarbon feedstock in a second reactor to a steam cracking process to form a second effluent comprising olefins including butadiene; (d) fractionating the second effluent into an olefinic product fraction comprising ethylene and/or propylene and an olefinic product fraction comprising mono-olefins containing 4 or more carbon atoms; and (e) recycling the olefinic product fraction comprising at least part of the ethylene and/or propylene as obtained in step (d) to the reactor in step (a).. .

Press hardened parts and method of producing the same
The present invention is to produce press hardened parts having excellent properties while avoiding a peeling of a plated layer or an intergranular cracking of a base material during a press forming, in such a manner that when a surface-treated steel sheet in which a zn—fe-based plated layer is formed on a surface of a base steel sheet is manufactured by a press hardening process, the forming is started after the surface-treated steel sheet is heated to a temperature that is not lower than an ac1 transformation point of the base steel sheet and 950° c. Or lower and the surface-treated steel sheet is then cooled to a temperature that is not higher than a solidifying point of the plated layer depending on the content of fe in the plated layer..

Methods for reducing asphalt pavement thickness, increasing aggregate-to-aggregate contact of asphalt paving materials, and improving low temperature cracking performance of asphalt paving materials
Methods for reducing asphalt pavement thickness, for fabricating asphalt paving material with increased aggregate-to-aggregate contact points, and for fabricating asphalt paving materials with improved low temperature cracking performance are provided. A method for reducing asphalt pavement thickness includes combining a base asphalt, an oxidized polyolefin, and an aggregate to form an asphalt paving material.
