The energy demand and the impact by fossil fuels use in the Mexico City Metropolitan Area, from 1988 to 2000

Temporary variation for the demand of refining products which are used in the Mexico City Metropolitan Area (MCMA) is presented. Its consequent energy contribution is evaluated from 1988 to 2000. The annual estimation was integrated from a detailed inventory of fuels volume, so as the calculus of its respective energy equivalence. The fuel quality specifications, which have been required by regional Air Quality authority for controlling emissions to the atmosphere, are also presented for the same period. The evolution demand of fuels, in term of volume, quality and its energy contribution for this area, is compared with the national demand. On this regard, fuel pool differs in each bound and the demand along the same period has been increasing on both regions but at different rates, with 21% at MCMA and 31% countrywide. In 2000, the MCMA demanded 14% of the internal refining products volume sales, which represented 17% of the energy contribution to the country for those fuels. Likewise, the energy use coefficient (GJ per capita) was applied to compare this region with country trends. During 1996 and up to 2000, the MCMA presented slightly minor energy use per capita, than the rest of the country, and this period was distinguished also for using cleaner fuels and for obtaining improvements in air quality. On the other hand, MCMA and country greenhouse gases emissions will increase because of their fossil fuel dependence, so several mitigation measures must be implemented in the next decades.     

铟生产中锌含量的控制

研究了在铟生产中的置换过程和电解精炼过程中的酸度对锌含量的影响,以及锌含量的控制。在置换过程中,当酸含量控制在15～25g/L时,能控制反应的速度,从而降低粗铟中锌的含量;在电解精炼中,溶液的pH值为2～3,可使铟中锌的含量降低至0 5μg/g,并提出了采用硫酸或氢氧化钠来控制溶液酸度的方法;用海绵铟熔铸阳极时,采用NaOH熔炼的同时,加入NaCl能降低碱性熔渣的黏度,提高NaOH对Zn(OH)2、Na2ZnO2等的吸收能力,降低铟中锌的含量。

废油循环再利用的研究

废油,是其中含有5%~10%为不能被利用的废物,而90%~95%是可以重新加工再利用的,使再生油资源成为解决我国目前能源困境的一个非常有效的途径,从石油中提炼基础油产品率很低,生产1 t至少需要5 t原油。从某种方面上讲利用再生废油要比开发原油经济的多,可以节省大量的时间和资金。近年来我国平均每年要进口2亿多吨原油,进口200多万吨润滑油,而且进口原油的产地大多又受战乱,政权更迭等政治因素影响。所以,对废油再生和利用,不仅具有重要的经济意义、环保意义,还具有重要的政治意义。
