Hydro-conversion of coal hydroliquefaction residue obtained from a 6t/day pilot plant of Shenhua Group in Shanghai was carried out under the hydrotreating condition. The coal hydroliquefaction residue and its product were extracted in sequence with <em>n</em>-hexane, toluene and tetrahydrofuran in a...

Based on general principles of metastable states and the mechanics of continuous media, the kinetic equation of settlement of granular material subjected to low level vibration and elastic stresses is developed. Because of confining pressure, the material remained nearly as a solid block and...

We seek to provide a general strategy to permit the study of non-equilibrium aspects of conformational transitions in various types of heteropolymers. The theoretical methods we have developed rely mainly on the Gaussian self-consistent approach that replaces the exact non-linear Langevin...
