The calculation of chemical structures and physical properties is the basis of petroleum refining optimization. In this article, a method to build an average molecule model for hydrocarbons and petroleum fractions is developed. 1H‐NMR, molecular weight, and elemental composition were used as input parameters to construct a single molecular model that represents the average chemical structure. The...
Delayed coking is an important petroleum resid conversion process. The processability of coking liquids is known to be dependent on the heteroatom compounds present in the coking liquids. Eight commercial delayed coking liquids were characterized by electrospray ionization (ESI) Fourier transform ion cyclotron resonance mass spectrometry (ESI FT-ICR MS) and gas chromatographic techniques. High relatively...
In this thesis, the preparation technology of UHMWPE microporous membranes was researched via TIPS method and supercritical propane extraction when liquid paraffin(LP) was used as diluent. Under the conditions of 100°C, 9MPa, 2h, 1.5kg/h, the extraction efficiency of extracting LP is up to 98.5% and the porosity of membranes is 32.65%.
