摘要

通过提纯甘蔗渣中的活性炭来减少废食用油中的游离脂肪酸,成功地生产出了生物柴油。在 400 oC 下用 H3PO4 对蔗渣中的 10 克活性炭进行活化,然后将其用作精炼废食用油的吸附剂。根据 SNI 01-2901-2006 标准进行油质检测,成功地将 ALB 含量从 4.16% 降至 0.336%,过氧化物含量从 6.99 mek/kg 降至 6.99 mek/kg。用 GC(气相色谱法)鉴定生物柴油形成化合物的结果是油酸、亚油酸和棕榈酸脂肪酸,分别为 43.4181%、10.5952% 和 38.6358。 在这项研究中,通过净化甘蔗浆的活性炭来减少废食用油中的游离脂肪酸,成功地制成了生物柴油。在 400 摄氏度的温度下,用 H3PO4 对质量为 10 克的甘蔗浆活性炭进行活化,然后将其用作精炼废食用油的吸附剂。根据 SNI 01-2901-2006 标准进行油质测试,成功地将 ALB 含量从 4.16% 降至 0.336%,过氧化物含量从 6.99 mek/kg 降至 6.99 mek/kg。根据 SNI 04-7182-2006,在油中加入比例为 1:6 的甲醇和 1%的催化剂,生产出生物柴油,酸值为 0.6731%,碘值为 57.3625%,生物柴油密度为 0.8599 克/毫升。 通过气相色谱法(GC)鉴定生物柴油形成化合物,得出油酸、亚油酸和棕榈酸脂肪酸的组成分别为 43.4181%、10.5952% 和 38.6358。

Pemanfaatan Karbon Aktif Ampas Tebu dalam Mereduksi Asam Lemak Bebas (Free Fatty Acid) untuk Pemurnian Minyak Jelantah sebagai Biodiesel
Pembuatan biodiesel telah berhasil dilakukan dengan pemurnian karbon aktif ampas tebu untuk mereduksi asam lemak bebas (free fatty acid) pada minyak jelantah. Karbon dari ampas tebu diaktivasi dengan H3PO4 pada suhu 400 oC dengan massa 10 g lalu digunakan sebagai adsorben dalam pemurnian minyak jelantah. Pengujian kualitas minyak sesuai SNI 01-2901-2006 dan berhasil menurunkan kadar ALB sebesar dari 4,16% menjadi 0,336% dan bilangan peroksida 6,99 mek/kg. Penambahan metanol pada minyak dengan perbandingan 1:6 serta katalis 1% menghasilkan biodiesel sesuai SNI 04-7182-2006 dengan bilangan asam sebesar 0,6731%, bilangan iod 57,3625% dan densitas biodiesel yaitu 0,8599 g/mL. Identifikasi senyawa pembentuk biodiesel dengan GC (Gas Chromatography) menghasilkan komposisi FAME oleat, linoleat dan palmitat yaitu 43,4181%, 10,5952%, 38,6358.   In this study, biodiesel has been successfully made by purifying the activated carbon of the sugar cane pulp to reduce free fatty acids in used cooking oil. The carbon from the pulp of sugar cane is activated with H3PO4 at a temperature of 400oC with a mass of 10 g and then used as an adsorbent in refining used cooking oil. Oil quality testing produced according to SNI 01-2901-2006 and succeeded in reducing ALB levels from 4.16% to 0.336% and 6.99 mek / kg peroxide. The addition of methanol to oil with a ratio of 1: 6 and 1% catalyst produced biodiesel according to SNI 04-7182-2006 with acid numbers of 0.6731%, iodine number 57.3625% and biodiesel density which was 0.8599 g / mL. Identification of biodiesel-forming compounds with GC (Gas Chromatography) resulted in compositions of FAME oleate, linoleic and palmitic respectively 43.4181%, 10.5952%, 38.6358.
