麻烦把下面文字翻译成英文,谢谢

氢氧化钡催化蓖麻油酯交换制备生物柴油
研究了以蓖麻油为原料,用氢氧化钡作为非均相碱催化剂,酯交换反应制备生物柴油。研究了反应醇油摩尔比、催化剂的量和反应时间对生物柴油收率和蓖麻油转化率的影响。结果表明,蓖麻油在以氢氧化钡为催化剂的酯交换反应中适宜条件为:醇油摩尔比6:1,催化剂量10:1,反应时间90 min

Preparation of biodiesel by Barium hydroxide catalyzed transesterification castor oil
Preparation of biodiesel from transesterification is studied with castor oil as raw material and barium hydroxide as a heterogeneous alkaline catalyst. What's more , the effect of  the reaction  methanol to oil molar ratio, catalyst amount and reaction time to the  yield rate of biodiesel and the conversion rate of castor oil are investigated. The results show that the appropriate conditions of the castor oil in the transesterification reaction with barium hydroxide as catalyst are methanol to oil molar ratio of 6:1,  catalyst amount of 10:1 and reaction time of 90 min.
