  Life cycle assessment of fuel cell vehicles a methodology example of input data treatment for future technologies

  摘要：

  Life cycle assessment (LCA) will always involve some subjectivity and uncertainty. This reality is especially true when the analysis concerns new technologies. Dealing with uncertainty can generate richer information and minimize some of the result mismatches currently encountered in the literature. As a way of analyzing future fuel cell vehicles and their potential new fuels, the Fuel Upstream Energy and Emission Model (FUEEM) developed at the University of California - Davis, pioneered two different ways to incorporate uncertainty into the analysis. First, the model works with probabilistic curves as inputs and with Monte Carlo simulation techniques to propagate the uncertainties. Second, the project involved the interested parties in the entire process, not only in the critical review phase. The objective of this paper is to present, as a case study, the tools and the methodologies developed to acquire most of the knowledge held by interested parties and to deal with their eventually conflicted - interests. The analysis calculation methodology, the scenarios, and all assumed probabilistic curves were derived from a consensus of an international expert network discussion, using existing data in the literature along with new information collected from companies. The main part of the expert discussion process uses a variant of the Delphi technique, focusing on the group learning process through the information feedback feature. A qualitative analysis indicates that a higher level of credibility and a higher quality of information can be achieved through a more participatory process. The FUEEM method works well within technical information and also in establishing a reasonable set of simple scenarios. However, for a complex combination of scenarios, it will require some improvement. The time spent in the process was the major drawback of the method and some alternatives to share this time cost are suggested.

  Synthesis of silanes with more than three silicon atoms are disclosed (i.e., (SinH(2n+2) with n=4-100). More particularly, the disclosed synthesis methods tune and optimize the isomer ratio by selection of process parameters such as temperature, residence time, and the relative amount of starting compounds, as well as selection of proper catalyst. The disclosed synthesis methods allow facile preparation of silanes containing more than three silicon atoms and particularly, the silanes containing preferably one major isomer. The pure isomers and isomer enriched mixtures are prepared by catalytic transformation of silane (SiH4), disilane (Si2H6), trisilane (Si3H8), and mixtures thereof.

  公开了具有三个以上硅原子的硅烷的合成方法（即 n=4-100 的 (SinH(2n+2)）。更具体地说，所公开的合成方法通过选择工艺参数，如温度、停留时间和起始化合物的相对量，以及选择适当的催化剂来调整和优化异构体比例。所公开的合成方法可以方便地制备含有三个以上硅原子的硅烷，特别是含有一种主要异构体的硅烷。纯异构体和异构体富集混合物是通过硅烷（SiH4）、二硅烷（Si2H6）、三硅烷（Si3H8）及其混合物的催化转化制备的。
