1) blending ratio of vacuum residue
掺渣比
1.
The optimum conditions were:feedstock preheating temperature 250℃,first and second riser outlet temperature 510,525℃ respectively,blending ratio of vacuum residue in feedstock about 35%,the mass fraction of discharging decanted oil 3%-4%,the recycling rude gasoline feeding above nozzle of recycling decanted oil,using LV-23 type FCC catalyst.
优化结果为:原料油预热温度250℃,一段提升管出口温度510℃,二段提升管出口温度525℃,原料掺渣比约35%,所产总油浆的3%~4%(质量分数)外排,粗汽油回炼时从二段提升管油浆回炼喷嘴的上方进料,采用LV-23型FCC催化剂。
2) high residue blending proportion
高掺渣比
3) residual oil blending
掺渣
4) residue blending ratio
掺渣率
5) GGBS replacement level
矿渣掺量
1.
Test results show that the freeze thaw durability and strength of GGBS concrete are greatly affected by the strength grade,curing regime and GGBS replacement level.
试验表明，强度等级、养护条件、矿渣掺量等因素对矿渣混凝土的强度、抗冻融耐久性有着显著的影响；矿渣混凝土的抗冻融耐久性明显优于同等级的普通混凝土；矿渣掺量愈大，矿渣混凝土的抗冻融耐久性愈
6) addition amount of waste residue
废渣掺量
1.
Study on the cognizance method of addition amount of waste residue to building materials product in the comprehensive utilization of resource;
建材产品资源综合利用中废渣掺量认定方法的研究
补充资料：渣比
slagtoironratio,slagratio：高炉冶炼每吨生铁的出渣量，即渣比＝Q渣/Q铁。Q渣—每批料的出渣量，t；Q铁—每批料的出铁量，t0。
