Tahe VR-based and SBR-modified high quality paving asphalt

After analyzing the working characteristics and fault forms of residuum pump at the bottom of vacuum tower of distillation unit, some technical measures are gradually found and used in practice.

The local chemical structure of non-porphyrin Ni in Liaohe vacuum residue was investigated by X-ray absorption fine structure (XAFS) spectroscopy.

All kinds of methane upgrading reactions of Liaohe vacuum residue, under conditions of existing decentralization catalysts, are examined, in order to explore the possibility of upgrading heavy oil by using of methane as hydrogen resource.

Multi-dimension separation and composition characterization of Dagang vacuum residue;

Fundamental study on mild thermal cracking of vacuum residue with industrial hydrogen donors;

Structure features of the supercritical fluid extraction and fraction tailing of Dagang vacuum residue;

Application of ultrasound in the viscosity reduction of vacuum residuum

The two processing schemes of high-sulfur vacuum residuum in SINOPEC Qilu Branch were compared from the viewpoint of techno-economy: one is to produce heavy asphalt through vacuum deep extraction process,the other is to produce light oil products through VRDS-FCC assembled process.

Several deasphalted oil samples were obtained from vacuum residuum and FCC slurry oil deasphalted at continuous propane deasaphalting pilot equipment.
