|
摘要
以向日葵秸秆、紫苏秸秆、花生壳和核桃壳作为研究材料,研究了材料粒径、吸附时间、吸附温度对其吸油能力的影响,以及该4种材料对3种不同油品的吸附性能;同时考察了4种吸附材料的保油性能和疏水保油性能。结果表明:4种材料的吸油能力依次为紫苏秸秆>向日葵秸秆>核桃壳>花生壳;向日葵秸秆、紫苏秸秆、花生壳、核桃壳的最佳粒径分别为40、20、60目和40目,最佳吸附时间分别为60、60、30 min和120 min,最佳吸附温度分别为30、50、30℃和30℃;在各自最优吸附条件下,4种材料对大豆油最大的吸附量分别为2. 91、4. 09、1. 05 g/g和1. 65 g/g; 4种材料对3种不同油品的吸附能力依次为大豆油>柴油>汽油;紫苏秸秆的吸油能力最强,同时其对3种油品的保油能力不低于75%,油水比可达1. 12。
With sunflower straw,perilla straw,peanut shell and walnut shell as research materials,the effects of particle size,adsorption time and adsorption temperature on oil adsorption capacity of four kinds of oil crops biomass materials were studied. The adsorption properties of these materials to three kinds of oils were also tested. In addition,oil retention capacities and hydrophobic oil absorption capacities of the four kinds of materials were also studied. The results showed that the oil adsorption capacity of perilla straw was the best,followed by sunflower straw,walnut shell and peanut shell. The optimal particle size,adsorption time and adsorption temperature of sunflower straw,perilla straw,peanut shell and walnut shell were 40,20,60 meshes and 40 meshes,60,60,30 min and 120 min,30,50,30 ℃ and 30 ℃,respectively. Under the optimal conditions,the maximum adsorption capacities of the four kinds of materials on soybean oil were 2. 91,4. 09,1. 05 g/g and 1. 65 g/g,respectively. The adsorption capacities of four materials on soybean oil were the strongest,followed by diesel oil and gasoline. Perilla straw had the highest oil absorption capacity,and its oil retention capacities on three kinds of oils were not less than 75%,and its oil-water ratio was up to 1. 12.
