摘要

我们强烈建议棕榈油厂使用棕榈壳和纤维作为锅炉燃料，以保持可持续的利用周期。棕榈油壳和纤维燃烧后产生的灰烬未得到最佳利用和管理，极有可能造成环境污染。本研究旨在利用棕榈油厂锅炉灰烬（ABKS）作为合成沸石/活性碳（ZKA）复合材料的原料。ZKA 复合材料可作为粗棕榈油（CPO）漂白过程中游离脂肪酸和胡萝卜素的吸附剂。根据 EDX 和 XRD 的表征结果，ABKS 的 Si、Al、C 含量分别为 40.71%、6.10%、0.66%：0.66%，并表明含有石英和菱锰矿矿物。用 NaOH 进行煅烧，然后在 100 °C 的温度下进行 24 小时的水热处理，可生成 ZKA，根据使用 XRD 和 EDX 进行表征的结果可知，复合材料中含有安山沸石和碳。根据 SEM 表征结果，ZAKA 复合材料的形态是多孔的，具有良好的粒度分布。根据漂白前后 CPO 中游离脂肪酸和胡萝卜素的分析结果，ZKA 复合材料减少了 15.67% 的游离脂肪酸和 16.34% 的胡萝卜素。由此得到的复合材料对游离脂肪酸和胡萝卜素具有良好的吸附能力，可以作为棕榈油行业循环经济应用中生物质废物利用的一种解决方案。

Sintesis Zeolit-Karbon Aktif Berbasis Abu Boiler Pabrik Kelapa Sawit Sebagai Adsorben Asam Lemak Bebas dan Karoten pada Crude Palm Oil

The application of palm shells and fibers as boiler fuel in palm oil mills is highly recommended to maintain a sustainable utilization cycle. The combustion of palm oil shells and fibers producing non-optimally utilized and managed ash generates a high potential for environmental pollution. This research aims to utilize palm oil mill boiler ash (ABKS) as raw material for zeolite/activated-carbon (ZKA) composite synthesis. ZKA composite uses as free fatty acids and carotenes adsorbent in the bleaching process of crude palm oil (CPO). Based on the results of characterization with EDX and XRD, ABKS contains Si; Al; C of 40.71%; 6.10%: 0.66% and indicates to contain quartz and cristobalite minerals. The calcination process with NaOH followed by a hydrothermal process at a temperature of 100 °C for 24 hours produces ZKA which is known from the results of characterization using XRD and EDX where the composite is indicated to contain analcime zeolite and carbon. Based on SEM characterization results, the morphology of the ZKA composite is porous and have good particle size distribution. Based on the results of analysis of free fatty acids and carotenes from CPO before and after bleaching, ZKA composite reduces 15.67% of free fatty acids and 16.34% of carotenes. The resulting composite has good adsorption capabilities for free fatty acids and carotenes and may be a solution for utilizing biomass waste as a circular economy application in the palm oil industry.
