The present disclosure provides a functionalized carbon black obtained by treating an oxidized carbon black with a sulfur-containing primary or secondary amine or a salt thereof. The disclosure also relates to a process for preparing such functionalized carbon black. Furthermore, the present disclosure relates a vulcanizable rubber composition including (i) a vulcanizable rubber component, and (ii) an oxidized carbon black and (iii) a sulfur-containing primary or secondary amine or a salt thereof, or a functionalized carbon black formed from these components. The disclosure also concerns an article made from the vulcanizable rubber composition. The functionalized carbon blacks disclosed herein are particularly useful for obtaining rubber compounds with low hysteresis and enhanced abrasion resistance, e.g. for the production of energy-saving tires.

Functionalized carbon black, preparation thereof and use in vulcanizable rubber compositions

An anti-fouling device includes an elongated displacement body insertable in a heat exchanger tube to reduce the flow cross-sectional area in a portion of the tube. A mount is connected to the elongated displacement body for attaching the device to an end of the heat exchanger tube. The mount is configured to hold the displacement body, when inserted into the tube, in a spaced relationship to the inner surface of the tube. The device reliably reduces fouling over an extended period of time without requiring maintenance or external controls, is easily installable, and can be retrofitted to existing heat exchangers. The device mitigates fouling related issues in heat exchangers subjected to hot combustion or process gases such as those encountered in the production of carbon black, fumed silica or other particulate matter, without contaminating the product recoverable from the process gas or having an adverse influence on the properties thereof.

Anti-fouling device for heat exchangers and its use

The present invention relates to a furnace black having a STSA surface area of at 130 m/g to 350 m/g wherein

Process for controlling the porosity of carbon blacks

Suggested is a carbon black composition showing a narrow Aggregate Size Distribution (ASD) characterized by a &#x394;D/Dvalue of about 0.58 to about 0.65 and a Relative Span (D&#x2212;D)/Dof about 0.5 to about 0.8, which is obtainable by means of a modified furnace reactor. The composition shows superior additive performance and allows producing e.g. bus or truck tires with improved wear resistance and reinforcement.

Carbon black compositions

The invention relates to a carbon black with a CTAB surface area of from 20 to 49 m/g, with a COAN greater than 90 ml/(100 g), and with a sum of OAN and COAN greater than 235 ml/(100 g). The carbon black is produced in a furnace reactor, where from 20 to 55% by weight of the feedstock used for the carbon black are introduced radially through a nozzle within the first third of the reaction zone, and the remaining amount of the feedstock used for the carbon black is introduced through a nozzle upstream at least one further point into the reactor. The carbon black can be used in rubber mixtures.
