China's Green Economic Growth and the Corresponding Energy Transformation [PDF]
, 2016 资源耗竭和环境污染已经成为中国可持续发展的严重制约，特别是雾霾等环境问题的大面积集中爆发，更是将这一问题摆在了公众和政府的面前。但是，对于中国这样的发展中大国，“发展是第一要务”，因为解决十三亿人口的吃饭和就业问题都离不开经济较快增长。如何在稳增长、资源节约、环境友好这三者之间的权衡取舍是政府面临的难题。因此，对于中国社会经济的可持续发展，关键是在兼顾经济增长的同时尽可能实现资源节约和环境改善。这就需要实现绿色经济增长的转型。 另一方面，气候目标成为中国经济发展的约束条件 ...

Simulation Study of Biomass Gasification [PDF]
, 2016 生物质气化是生物质利用过程中热效率较高的一种方法，同时也是一种十分重要的可再生能源利用方式。本文采用AspenPlus模拟软件，结合吉布斯自由能最小原理，建立了生物质气化反应器模型，模拟研究了不同操作参数对气化结果的影响，同时对三种气化剂下的气化结果进行了对比分析。 在三种气化剂的模拟结果中，同一操作参数对气化结果的影响有一定共通性：（1）随着气化温度的升高(600～900℃)，一氧化碳体积分数升高，二氧化碳和甲烷体积分数降低，但氢气体积分数变化不大；气体的热值升高（700℃以上），气体产率先升高后降低，
