The proton resonant properties in 1.Ne, which determine the reaction rate of the key stellar 1.O(α,p)1.F reaction, have been studied by using a technique of proton resonant elastic scattering of 1.F+p. A 4.22 MeV/nucleon 1.F radioactive ion (RI) beam was produced via a projectile-fragmentation reaction, and separated by a Radioactive Ion Beam Line in Lanzhou (RIBLL). By bombarding a thick (CH2)n target, the energy spectra of the recoiled protons were measured by two ΔE-E silicon telescopes at the center-of-mass scattering angles of θc.m.≈1.5°±5°, θc.m.≈1.2°±8°, respectively. Several proton resonances in 1.Ne were ob served clearly. A further R-matrix analysis of the experimental data is under way to determine the resonant parameters. The present work reports the preliminary results briefly.

生物油是唯一的液体含碳可再生资源,因其成分复杂、热值低、酸度高、粘度大等特点,必须经过提质才能进一步利用。生物油电化学提质是一种条件温和、易于控制的新兴提质方法,但仍面临生物油聚合结焦的问题,降低了提质生物油的品质和收率。通过对含有不同浓度乙酸和富芳香组分(Aromatic-Rich Fraction,ARF)的调制生物油分别进行电化学提质实验,对电化学反应后的溶液和焦表征分析,研究了乙酸和ARF对焦产率的影响规律,探讨了乙酸和ARF对生物油聚合结焦的影响机制。结果表明,乙酸能抑制生物油聚合结焦,加入浓度1.的乙酸可降低焦产率约25%,继续增加乙酸浓度会进一步降低焦产率;而ARF则会促进生物油聚合结焦,当ARF浓度从60%升到70%时,焦产率增加了约70%,当ARF浓度升到80%后,焦产率增加了约1.0%。乙酸能抑制生物油中酚类物质自缩合,降低了聚合结焦反应的速率,而ARF则增强了羟醛缩合反应,提高了聚合结焦反应的速率。
