So some renovations should be made,for example,increasing the solvent ratio of propane deasphalting;using hydrofinishing instead of clay treating;mo...
By controlling reaction condition in different steps and hydrogenated with Raney Ni,most of components were converted into industrial grade p-menthane without purification.
Preparation of EGD air-cooling two-stroke-cycle gasoline engine oil and TC-W3 water-cooling two-stroke-cycle gasoline engine oil was studied by using hydroisomerizing base oil.
Technology Progress of producing BTX aromatics from heavy fraction of pyrolysis gasoline and correlative hydrodealkylation and non-aromatics hydrocracking techniques were reviewed in this paper.
The polymerised product (mainly diisobutylene ) can be hydrogenated to be used as gasoline blending agent replacing MTBE, or separated as fine chemical feedstock.
The quality of diesel oil producing was advanced by isomery pour point depression technique applying in hydrogenation unit in Harbin Petroleum Company Branch of PetroChina.
The role and application of hydrofinishing to lube oil processing were described. Having Compared with clay refining, the trend of development of lube oil hydrorefining technology was given.
The catalysts used to hydrogenate polymer containing polydiolefin units are introduced in this paper.The mechanism of SBS hydrogenation and the development of the kinetics are also referred to.
