Abstract

Furfural can be applied in various industrial fields as a solvent in the petroleum processing industry, lubricant manufacturing materials, nylon, shoe dyes, insecticide raw materials, herbicides, and fungicides. The method used in Furfural uses the supra yield process method, which can save energy, have high product purity, and do not produce by-products. The process of making fulfural with the supra yield method is bagasse from the separator basin is transported to the hydrolysis reactor to be homogenized with a 98% H2SO4 catalyst in a ratio (6: 1). Next is the hydrolysis and dehydrolysis process, where the hydrolysis process takes place in a reactor with a temperature of 700C and a pressure of 1 atm with a time of 1 hour using a semi-batch process heated using steam. The hydrolysis reaction results in pentose, which flows to the rotary vacuum filter to separate the cake and the filtrate. Then, in the dehydrolysis process, the pentose results from the previous process will be converted into Furfural using an H2SO4 catalyst and water, with a temperature of 2000C and a pressure of 15 atm for 75 minutes. Furthermore, the temperature will be lowered to 1000C. The final process is the separation and purification of the product; the mixer will add Toluene, and then it will flow to the distillation tower to separate Toluene and Furfural to get pure Furfural. As a top product, Toluene will evaporate at a temperature of 1150C. The final product with a purity of 99.9%. The primary tool used is a dehydration reactor that dehydrates pentose into Furfural. Abstrak Furfural dapat diaplikasikan pada berbagai bidang industri sebagai pelarut dalam industri pengolahan minyak bumi, bahan pembuatan pelumas, nilon, pewarna sepatu, bahan baku insektisida, herbisida dan fungisida. Adapun metode yang digunakan dalam fulfural yaitu menggunakan metode supra yield process, dimana pada metode ini dapat menghemat energi, kemurnian produk yang tinggi dan tidak menghasilkan produk samping. Proses pembuatan fulfural dengan metode supra yield yaitu ampas tebu dari bak separator diangkut menuju reaktor hidrolisis untuk dihomogenkan dengan katalis H2SO4 98% dengan perbandingan (6:1). Selanjutnya yaitu proses hidrolisa dan dehidrolisa, dimana proses hidrolisa berlangsung dalam reaktor dengan suhu 700C dan tekanan 1 atm dengan waktu 1 jam dengan menggunakan proses semi batch yang dipanaskan menggunakan steam. Hasil dari reaksi hidrolisa adalah pentosa yang selanjutnya dialirkan menuju rotary vacum filter untuk dipisahkan antara cake dan filtratnya. Kemudian proses dehidrolisa, hasil pentosa dari proses sebelumnya akan diubah menjadi fulfural dengan menggunakan katalis H2SO4 dan air, dengan suhu 2000C dan tekanan 15 atm selama 75 menit. Selanjutnya, akan diturunkan suhunya menjadi 1000C. Proses akhir yaitu pemisahan dan pemurnian produk, pada mixer akan ditambahkan toluena, selanjutnya akan dialirkan menuju menara destilasi untuk memisahkan toluena dan fulfural agar mendapatkan furfural yang murni. Toluena berupa produk atas akan menguapa pada suhu 1150 C. Produk akhir dengan kemurnian 99,9 %. Alat utama yang digunakan yaitu reaktor dehidrasi yang berfungsi untuk mengdehidrasi pentosa menjadi furfural. Kata Kunci: ampas tebu; furfural; reaktor dehidrasi; supra yield process

Abstract

There are many ways for preserving wood through the use of agricultural or biomass waste like bamboo. Its utilization can be used as a safe natural wood preservative for the community. In order to obtain a qualified liquid smoke and consumed-safe it is necessary to engineer the condenser conduit pipes. As a consequence, this study needs a performance test of condenser conduit pipe on pyrolysis reactor device. The purpose of this study is to determine the performance quality of pyrolysis reactor device based on the optimum of long condenser conduit pipe and to determine the reaction order. In this study, the pyrolysis process of 2,5 kgs bamboo was using a pyrolysis reactor in optimum operating conditions, conducted with condenser conduit pipes size 23 cm, 33 cm, 43 cm, 53 cm, 63 cm and 73 cm at temperature of 250ºC for 2 hours. The results of this study indicate that the optimal liquid smoke yield is obtained from 23 cm long condenser conduit pipe (21.66%); the mass of lost material is 52.49% found in 73 cm pipe; the performance of the pyrolysis reactor is 206.25 found in 23 cm pipe g/hour.m; and the reaction occured was included as the first order of reaction.
