【摘要】 随着温度的升高,煤沥青炭化产物的微晶尺寸逐渐增大。约在450℃,由于微晶重排,出现微晶分裂(Crystallite Splitting)现象。改质沥青由于含有较多的β-树脂和中间相QI,使其在炭化过程中微晶生长速率增快。更多还原

【Abstract】 Microcrystallite. grains in products from carburization of coal tars become bigger as temperature increases. Crystallite splitting occnrs at 450℃ due to mi crocrystalli te rearrangement. Chemically altered coal tars contain much P-resin and an intervening phase QI, both of which help accelerate the microcrystallite growth in carburi zation of thesecceoal tars.更多还原
