摘要
采用两种典型的高酸原油进行加氢改质技术研究。结果表明,在低压、高空速条件下,低硫、高酸的蓬莱原油经加氢改质后可作为普通原油加工;在高压、低空速条件下,高硫、高酸的重质胜利混合原油经加氢改质后,酸值、硫含量、残炭以及重金属含量大幅度降低,°API提高,加氢原油的常压渣油可直接作为催化裂化原料。另外,考察了操作条件对加氢脱酸的影响。结果表明,在低压、高空速条件下,随着温度的升高,脱酸率增大;随着体积空速的增大,脱酸率降低;氢分压降低会显著降低脱酸率。
The hydro upgrading of highly acidic crude oils was studied using two types of typical crude oils. The results indicated that Penglai crude could be processed as ordinary crude after hydro-upgrading under low pressure and high LHSV. The acid value,contents of sulfur,CCR and heavy metals of Shengli commingled crude decreased significantly after hydro-upgrading under high pressure and low LHSV, and its API gravity increased as well. The atmospheric residue of hydro-upgraded Shengli commingled crude could be used as RFCC feedstock directly. The relationships between operating conditions and hydro-deacidification were investigated. It was found that under low pressure and high LHSV, the acid removal rate increased with the increase of reaction temperature and decreased with increase of LHSV;the decrease of hydrogen partial pressure could cause the reduction of acid rem rate significantly.
