加工劣质原料油增产丙烯专用催化剂设计

为了扩大催化裂化进料来源,中山天乙石化公司在该公司产量为40万t/a的催化裂化装置上加工M-100类劣质原料油,该类原料油性质较差、金属含量高、裂化难度大,因此,对所使用的催化剂提出了苛刻的要求。中石化石油化工研究院(RIPP)和中石化催化剂长岭分公司设计并生产出该装置所专用的催化剂CMO,经实验评价,CMO具有很好的活性和活性稳定性、优异的抗金属污染性能、优秀的重油转化能力,能有效地增产丙烯。

The influence of international oil price fluctuation on the exchange rate of countries along the “Belt and Road”

In recent years, the international crude oil price has become increasingly volatile. It influences the exchange rate changes of relevant countries through economic growth, price level, international balance of payments, and other channels. Such exchange rate fluctuations have caused certain risks for the development of China’s “Belt and Road” Initiative. This article analyzes the impact of oil price changes on the exchange rates of countries. Because the fluctuation of oil prices and exchange rates has shown the characteristics of multiple time scales, this study used the empirical mode decomposition (EMD) method to obtain the long-cycle and short-cycle sequences of oil prices and the exchange rates of various countries, then analyzed the impact of oil price changes on exchange rates under different time scales. The results showed that oil price fluctuations have an impact on the exchange rate changes of countries along the “Belt and Road” under different time scales. However, this effect is asymmetric between oil-producing countries and non-oil-producing countries, and the transmission path of oil prices to exchange rates varies from cycle to cycle.

水轮发电机推力油槽油位下降的原因分析与处理

2009年末,大唐碧口水力发电厂3号水轮发电机组在运行的一周内出现三次推力油槽油位下降的现象,给机组的正常运行构成了极大的威胁,同时也增加了大量的维护成本。经过对可能造成推力油槽油位下降多种原因进行分析论证,最终确认导致的推力油槽油位下降的原因为推力轴承油冷却器渗漏。在秋检时对3号机10台推力轴承油冷却器进行打压试验,发现4号油冷却器存在渗漏现象,将4号冷却器进行了整体更换后回装,机组运行至今再未发生推力油槽油位下降的现象。

Oil Crisis,Market Reforms,and Human Welfare： An Econometric Analysis of the Australian Economy

As an active trader in international crude oil and petroleum product markets, Australia＇s human welfare is affected by oil crisis and contagion from the perspectives of economic growth, income inequality, and environmental sustainability. This paper investigates the impacts of oil price shocks upon Australia＇s gross domestic product （GDP） growth, Gini coefficients, and carbon dioxide emissions per capita from 1970 to 2012 with yearly frequency. Hypotheses concerning whether Australia＇s economic immunity against oil crisis is affected after the deregulation of oil market and whether endogenous oil price shocks account for more variations in human welfare than exogenous oil price shocks are tested. The methodologies include a theoretic model and a series of econometric tests. For the short-run dynamics, oil price is integrated into the model both linearly and non-linearly. Oil price shocks are categorized into exogenous and endogenous shocks. The conclusions are that inflated oil prices exert mainly non-linear negative impacts upon human welfare indicators and exogenous shocks induce endogenous shocks through labor price, Consumer Price Index （CPI）, interest rate, and exchange rate. For the long-run equilibrium, non-linear shocks＇ effects decay more slowly than linear shocks and the impacts of endogenous shocks last longer than that of exogenous shocks. Finally, oil market policies are evaluated and proposed.     

高压禁油数字压力计检定方法的探讨

阐述了在检定数字压力计时遇到的一种高压禁油数字压力计,这种压力计准确度高（±0．1％）、测量范围大（0—10MPa）,在检定时必须禁止和任何有油物质接触。现用常规检定标准器有数字压力发生器（准确度±0．01％,测量范围-0．1～314MPa）和一等活塞式压力计（准确度±0．02％,测量范围0～60MPa）两种。一等活塞式压力计使用的工作介质是蓖麻油,是检定二等活塞式压力计专用的标准器,受地区重力加速度的影响输出的压力值也不是整数,所有标准器都不能满足这种数字压力计的检定条件,而建立一套满足该检定条件的标准装置投资成本较高。通过实验、研究、分析,摸索出一种用一等活塞式压力计检定这种高压禁油数字压力计的方法。
