The results showed that when the volmetric fraction of anhydrous alcohol is 10%~15%,the No. 93 alcohol gasoline meeting the national standard GB 17930-1999 can be blended out by the No. 90 gasoline of Luoyang General Petrochemical Works.
20 tons ABG was blended out according to the defined formulation as testing sample. The rig test for 20 tons of ABG sample showed that both HC and CO in exhaust gas of ABG decrease by 18.5% and 22.4% respectively. The lowest fuel consumption decreases by 4.25%.
This paper analyzes the status of motor gasoline production in China and the disparity to the new international stan dards of clean motor gasoline. Several tech niques such as desulfuration of gasoline,alkene removing of gaso line,high octane blending value production,production of gasoline cleaning agents and alcohol-containing gaso line can be utilized to meet the demands of new stan dards of clean motor gasoline.
The Oil resistance of dynamically vulcanized PVC/NBR thermal plastic elactomer(TPE)was systematically investigated in this paper.Results showed that this TPE had better resistance to oils ,especially to lead-free-gasoline,alcohol-contained galoline and oxygenated gasoline. The main reason for this is the existence of the Synergistic Networkis TPE.The synergistic network Could prevent oils and solvents from permeating, Lower the permeating rate and as a results, increase the oil resistamce.
The effects of anhydrous alcohol,dispersant and water on the quality and storage stability of the No.93 alcohol blended gasoline(ABG) were studied.The results showed that when the volmetric fraction of anhydrous alcohol is 10%~15%,the No.93 alcohol gasoline meeting the national standard GB 17930-1999 can be blended out by the No.90 gasoline of Luoyang General Petrochemical Works.When the water content is less than 0.4%,the ABG keeps homogeneous phase at -10℃.20 tons ABG was blended out according to the defi...
The determination methods for olefins, aromatics and real colloids content involved in GB 17930-1999 standard, as well as the inspection method standard for alcohol-containing gasoline are discussed in this paper. It is suggested that the olefins and aromatics determination methods shall be revised, real colloids inspection method shall be unified.
