Obtaining and Use of Coumarone-Indene-Carbazole Resin as a Modifier of Road Petroleum Bitumen. 2. Setting the Type and Amount of Catalyst

In the presence of various catalysts (TiCl4, AlCl3, H2SO4), the process of obtaining a coumarone-indene-carbazole resin (CICR), which is produced from liquid products of coal coking, and its subsequent use for bitumen modification was investigated. The influence of the catalyst type on the yield and modifying properties of CICR (change in thermoplastic and adhesive properties of bitumen after adding the obtained resins to them) was studied.

Production of Distilled Bitumen from High-Viscosity Crude Oils of Ukrainian Fields

The characteristics of initial crudes of Yablunivske field (Poltava, Ukraine) and the properties of blended crudes have been examined to select the ways of their further processing. The crude oils were found to be heavy high-sulfuric oils without light distillates. The possibility of obtaining paving bitumen from blended crudes under study has been considered. Distilled bitumen obtained through distillation of this blend was found to meet the requirements for commercial paving bitumen 100/150.

Preparation and Application of Coumarone-Indene-Carbazole Resin as a Modifier of Road Petroleum Bitumen. 1. Influence of Carbazole:Raw Materials Ratio

The possibility of effectively using carbazole as an improver of coumarone-indene resin for use as a modifier of petroleum bitumens is studied. All starting materials for the production of coumarone-indene-carbazole resin (CICR) were obtained from various products of the coal coking process. The influence of raw material composition (amount of carbazole added to an industrial indene-coumarone fraction) on resin yield and its modifying properties was studied.
