Sequential extraction and separation of medium coal tar pitch(MCTP)usingsupercritical fluid were carried out in semicontinuous apparatus.

Solvothermal synthesis of cabon-encapsulated metal nanoparticles from deoiled asphalt

The visbreaking reaction for the feedstock of deoiled asphalt from butane deasphalting unit (BDOA) blended with full distillation range FCC slurry (FDRFS) or the light FCC decanted oil of IBP-460℃(LFS) distillation range were investigated in an autoclave.

Deoiled asphalt was chosen as the carbon source and FeCl3 as the catalyst,to prepare vapor-grown carbon fibers(VGCFs)with different morphologies,by chemical vapor deposition,in an atmosphere of argon and hydrogen.

Influence of petroleum pitch coating graphite on electrochemical performance of lithium ion battery;

The thesis overviews the present development of the antiseptic outer layer of the steel tube, comparing with the petroleum pitch antiseptic layer, epoxyasphact antiseptic lay, etc.

Pitch spheres are obtained with a novel suspending method using petroleum pitch as a main raw material.

Evaluation and utilization optimization of a deasphalted oil hydroisomerization products based on carbon number distribution and hydrocarbon type analysis;

The experimental results show that the conversion of vacuum gas oil(VGO), deasphalted oil(DAO), atmospheric resid(AR), mixed oil and topped light slurry are 74.

This paper introduced the problems after SPC transformed the diesel hydrogenation plant into deasphalted oil hydrogenation plant, analyzed the causes of them, and put forward the solution through process transformation and modification of processing parameters.
