The influence of the design of dual-zone ZoneFlow type structured catalytic reactors (Fig.1) on their performance in natural gas steam reforming under commercial operating conditions is studied by mea
In this research, heterogeneous catalytic ozonation was used in a ceramic membrane system to investigate its effect on the formation of trihalomethanes (THMs), which are recognized as cancerous agents
Novel monolithic catalysts were prepared with Pd as the active component, porous hollow silica nanoparticles (PHSNs) as washcoat and monolithic cordierite as the monolithic ceramic substrate, as shown
It is well-known that the conventional supported catalyst powders usually suffer from a large flow resistance, and the poor heat transfer through the powders will easily lead to unacceptably non-unifo
The low-temperature-low-pressure methanol synthesis from syngas over CuO/ZnO/Al2O3-based catalysts is a mature and well-developed process and many large industrial plants are in operation.Due both to
The convection and diffusion processes in porous media are widely applied into chemical engineering, energy, environment and biology fields, such as chemical reaction in packed beds and mass transfer
Barium is considered as the most efficient promoter in Ru/MgO catalysts.It was found that Ba2+ could not be adsorbed directly on the surface of Mg(OH)2 having positive charge during preparation of sup
Hydrocarbon selective catalytic reduction of NOx (HC-SCR) is an attractive process to reduce emissions from diesel engines [1].Ag supported on Al2O3 is a promising catalytic system [2].Problems to sol
目的 研究酿酒酵母突变株Y518高产谷胱甘肽的潜在机制,为代谢工程进一步构建谷胱甘肽高产菌株提供新的思路.方法 提取酵母总RNA进行高通量测序,并通过基于RNA高通量测序的转录组分析,筛选出与谷胱甘肽相关的差异表达基因.结果 转录组的统计数据分析表明共有1125个差异表达基因(fold-change>=2.0,FDR<=0.001)上调,503个下调.其中13个基因富集在谷胱甘肽代谢通路.γ-谷氨
目的:魔芋粉和海藻酸钠是两种可溶性膳食纤维,能被用来当做强筋剂使用.方法:本文通过分别向面粉中添加0.1%,0.2%,0.3%,0.4%,0.5%的魔芋粉和海藻酸钠,以不添加魔芋粉和海藻酸钠的面粉为对照,利用粉质仪和拉伸仪测定面团的流动性,利用快速粘度分析仪测定面粉热力学性质,探究魔芋粉和海藻酸钠对面粉流变性和热力学性质的影响.结果:添加0.5%魔芋粉使面粉吸水率从58.7%提高到62.6%,0.
