Polyether based polyurethanes are among the most interested polymers which have been used suitably for the biomedical applications, especially in cardiovascular system. In order to meet the requirements of the artificial heart program in our college, two sorts of polyether based polyurethane elastomers, PU-BD and PU-MC, were synthesized both based on prepolymer formed by the reaction of polytetramethylene ether glycol and diphenyl methane-4, 4′-diisccyanate, with 1, 4-butanediol and 3, 3′-dich...

Synthesis of biodiesel by transesterification of rapeseed oil and methanol catalyzed by KOH/Al2O3 solid base was studied. The catalyst was prepared by isochoric impregnation. Effects of some factors on the transesterification were investigated systematically and reaction conditions were optimized. The optimum reaction conditions on KOH/Al2O3 catalyst were: mass ratio of KOH to Al2O3 20%; calcination temperature 400℃ for 5h; molar ratio of methanol to oil 12:1, the amount of catalyst 5wt%; reaction temperature 60℃ and reaction time 2h.

采用等体积浸渍法制备了KOH/Al2O3负载型固体碱催化剂，并将其用于菜籽油与甲醇酯交换法合成生物柴油的研究；分别考察了催化剂附载量、锻烧温度、醇油摩尔比、反应温度、反应时间等条件对生物柴油产率的影响；结果表明：用等体积浸渍法，在400℃煅烧5h，制得负载量为20%的KOH/Al2O3催化剂。

The journal well informs the research advances in this field, ranging from marine palynomorphs to higher land plants, including systematics, evolution, palaeobiology, palaeoecology, biostratigraphy, biochronology, palaeoclimatology, paleogeography, palaeoenvironmental reconstructions, palaeobotany and palynology etc.

By comparison among concentration of nitrogen compounds, relative contents of pryyolic N-H shielded carbazoles and parameters of C21-/C22+、Pr/nC17 , the results show that slight biodegradation has little effects on the relative contents and distribution of pyrrolic nitrogen compounds, but has certain effect on its concentration.

根据2类原油中含氮化合物浓度、屏蔽型含氮化合物的相对含量与反晕原油生物降解的地化参数C21-/C22+、Pr/nC17等指标的对比研究，发现生物降解作用对该区原油中含氮化合物的相对含量及其分布影响不显，运移作用仍然是造成含氮化合物分馏的主要因素。

For example, in order to generate an economically viable amount of biodiesel product, a conventional biodiesel plant contains large, batch-type reactors, large separation units (eg, decanters, centrifuges, clarifiers), and distillation columns as tall as 50 to 200 feet or more.

例如，为了产生一种经济上可行的生物柴油生产量，传统的生物柴油厂包含大，批次型反应堆，大型分离单位（例如，倾析器，离心分离，澄清池），并精馏塔一样高50至200英尺或更多。
