The mesophase pith was synthesized based on effects of a high-pressure thermal condensation and feed (PFO/FCC-DO) blending. The reaction conditions were designed by fluidity and reactivity of each feed during the thermal reaction. The high-pressure thermal condensation process disturbs distillation of the volatile compounds in pyrolysis fuel oil (PFO); the fluidity can be controlled. In the blending process, PFO, which has a high thermal condensation reactivity, and fluid catalytic cracking-decant oil (FCC-DO), which maintains fluidity, interacted with a synergistic effect. Thus, mesophase pitch with a large mesophase content was manufactured by the two above processes.

미국 D.C. 연방항소법원의 Verizon 판결은 ISP에 대한 FCC의 관할권을 인정하고, 나아가 오픈 인터넷 정책이 가져올 선순환 효과를 일응 인정하였다는 점에서 매우 큰 의미를 지니지만, 한편 망 중립성을 구현함에 있어 ISP를 보편적 역무 제공자로서 취급해서는 안 된다는 과제를 남 겼다. 우리나라는 전기통신사업법에 방송통신위원회 의 관할권 및 보편적 역무 제공자로서의 취급에 관한 명문 규정이 마련되어 있어 망 중립성에 관 하여 실질적인 논의에 집중할 수 있는 환경이 마 련되었다. 비록 국내 인터넷 시장 환경이 미국에 비하여 경쟁적이기는 하나, 마찬가지로 경쟁적인 시장 환경을 갖추고 있는 EU에서도 적극적인 망 중립성 정책이 채택되고 있는 점을 감안하면 Verizon 판결의 의미를 축소하기는 어렵다. 오히 려 헌법적⋅경쟁법적⋅형사법적 관점에서 망 중립 성을 통해 추구할 수 있는 가치를 면밀히 검토해야 한다. 아울러 ISP와 CP 사이의 비용부담 문제로 나타 나고 있는 현재의 망 중립성 분쟁을 해결하기 위해 서는 QoS 및 전송차등화에 대한 적극적인 연구가 필요하다. QoS 보장 서비스가 망 중립성을 해한다 는 단편적인 시각에서 벗어나, 경쟁과 혁신을 촉진 할 수 있는 규제의 방향을 검토하는 것이 보다 현 실적인 접근법이라고 생각된다.

In this study, toluene catalytic oxidation was investigated using various metal components (Cu, Ce, Ni, La and Zr) supported on Used FCC zeolite for the application of the waste recycling and odor reduction. Among the metals, 5 wt% Cu/zeolite showed the best catalytic activity. 100 % conversion was achieved at 300℃ which was 50℃ lower than that of other metal components. As increasing the amount of doped Cu, the CuO was formed and the surface area and pore size were decreased. By the reduction treatment before toluene oxidation, the catalytic activity of the oxidation below 250℃ was improved. No decrease of conversion was observed during the continuos reaction at 300℃ for 48 h.

Partial mesophase (PM) pitch precursor was prepared from fluidized catalytic cracking-decant oils (FCC-DO) by chemical reaction in the presence of Br2. The PM pitch heated-treatment at 420℃ for 9 h exhibited the softening point of 297℃ with 23% yield, and 55% anisotropic content. The PM pitch precursor was melt-spun through circular nozzle by pressurized N2, stabilized at 310℃, carbonized at 700℃, 1000℃, and 1200℃. The enough stabilization introduced 16.4% of the oxygen approximately. The stacking height (Lc002) and interlayer spacing (d002) of the as-spun fibers were 4.58 nm and 3.45a and the value became minimum and maximum at 700℃ respectively in the carbonization procedure. The tensile strength increased with an increase in the heat treatment temperature exhibiting highest value of 750 MPa at 1200℃ carbonization.
