本研究采用120-1环状柱状物，在室外条件下培养油茶。考察了不同通气量下的传质情况，以及收获率对生产率和生化成分的影响。通过全面评估生产率来评估该系统的潜力。试验采用了两种不同的方案来模拟全尺寸工厂并确定“总面积生产率”(OAP)。2003年8月，在七根虚拟柱之间放置了一根实验柱(全尺寸柱)。所有的反应器都布置在壁距0.8m的地方，中心位于等边三角形的顶点。第二个实验柱(隔离柱)被放置在一个单独的区域，在完全阳光下。在第一次实验中，尽管有虚拟单元的遮蔽，但全尺寸柱的平均体积生产率并不显著低于孤立柱(0.46vs0.49g L-1天-1)。可见太阳辐射(PE)的平均OAP和转换效率分别为36.3g m(-2)d(-1)和9.4%。在第二次实验中，全尺寸色谱柱的平均体积产率为0.42g L(-1)天(-1)。OAP和PE分别为38.2g m(-2)d(-1)和9.3%。(C)2006爱思唯尔B.V.保留所有权利。
In this study, 120-1 annular columns were used to cultivate Tetraselmis suecica outdoors. The mass transfer at different aeration rates and the influence of the harvest rate on productivity and biochemical composition were investigated. The potential of the system was evaluated by estimating productivity at full-scale. Two different arrangements to simulate a full-scale plant and determine the "overall areal productivity" (OAP) were experimented with. In August 2003, one experimental column (full-scale column) was placed between seven dummy columns. All the reactors were positioned at a distance of 0.8 m wall to wall and centred at the vertices of equilateral triangles. A second experimental column (isolated column) was placed in a separate area under full sunlight. In August 2004, the columns were placed side by side in an east-west oriented row at a distance of 0.24 m wall to wall.In the first experiment, the mean volumetric productivity of the full-scale column was not significantly lower than that achieved by the isolated column (0.46 against 0.49 g l(-1) day(-1)) in spite of the shading by the dummy units. The average OAP and efficiency of conversion of visible solar radiation (PE) were 36.3 g m(-2) day(-1) and 9.4%, respectively. In the second experiment, the full-scale column attained a mean volumetric productivity of 0.42 g l(-1) day(-1). The OAP and the PE were 3 8.2 g m(-2) day(-1) and 9.3%, respectively.
