, 2009 以新疆克拉玛依油田采油污泥为对象,分别采用热重分析仪和小型流化床热解反应器研究了含油污泥的热解过程及其热解效果。结果表明,油泥热解主要经历了失水、轻质组分挥发、重组分快速热解失重和缓慢失重4个阶段,热解过程基本符合一级动力学方程,提高热解的升温速率,可使油泥的最大失重速率Dm ax、失重速率峰值温度mθax、升温终点的最大失重率都随之增加,表现在动力学上,反映出表观活化能和碰撞频率因子的同时升高,即提高油泥热解转化率的同时也影响了热解效率。失水油泥用流化床热解,在热解温度600℃、反应时间3 m in时,

Unveiling Entropy‐Driven Hard‐Tough Synergy Mechanisms in High‐Entropy Carbonitride Ceramics
Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT High‐entropy ceramics manifested promise for extreme environments, yet their phase stability and mechanical synergy mechanisms remain elusive. Herein, entropy‐difference carbonitrides, including (TaTiV)CN, (TaTiVNb)CN, and (TaTiVNbHf)CN, were designed and consolidated via spark plasma sintering.

, 2016 近年来，随着石油、煤炭等化石燃料日益短缺，生物质能的开发利用倍受青睐。其中富木质素类生物质来源广泛，却尚未得到有效利用，其主要工业来源包括造纸黑液及木质纤维素发酵渣等，然而不论何种生物质物料，其热解液不可避免的存在组成复杂、热值偏低的弊端。因此，通过催化热解或与塑料共热解方式对热解液进行提质，成为生物质热解相关研究领域中的热点方向。另一方面，逐年增加的大量电子垃圾的无害化处理和再利用是关系环境、能源、材料等诸多领域的重要内容。因此，作为电路板主要成分的酚醛树脂的热解特性研究具有重要价值。鉴于此 ...

Advances in Thermoelectric Cu2ZnSnS4: From Structure, Synthesis to Performance
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Thermoelectric technology has the capacity to directly convert waste heat into electricity and vice versa. For a long time, Cu2ZnSnS4 (CZTS) has been extensively researched in the domains of solar cells and photocatalysis due to its exceptional photovoltaic properties, but its wide bandgap prevents it from being favored in thermoelectrics ...
