“…χ-Al 2 O 3 is one of the most acidic modifications of alumina. χ-Al 2 O 3 has the concentration of the Lewis acid sites 1.8-4.0 times more than γ-Al 2 O 3 [6]. Therefore, the χ-Al 2 O 3 presence as part of alumina catalysts and catalyst supports structure in various petrochemical and oil refining catalytic processes is unfavorable.…”

Abstract:The presence of χ-Al 2 O 3 resulting from thermal decomposition gibbsite as part of alumina catalysts is unfavorable because of its acid characteristics. One of the available techniques of χ-Al 2 O 3 removal is crystallization under hydrothermal conditions into boehmite, which is a main precursor of active γ-Al 2 O 3 . The influence of products of the hydrothermal treatment of χ-Al 2 O 3 obtaining in result of thermal decomposition gibbsite under T = 150-200 • C, P = 0.5-1.5 MPa and pH = 4.0-9.2 were studied. The hydrothermal treatment products in these conditions are gibbsite and boehmite phases which are formed coincidently by parallel ways. In the alkaline medium at pH = 8.0-9.2 three-dimensional parallelepiped boehmite crystals with the edge length > 200 nm are formed, at pH = 4.0 two-dimensional rhombic-shaped plates with thickness 20-100 nm and with the edge length~80-500 nm are formed. Crystallization of coarse boehmite particles promotes the formation of large and closed mesoporous.

“…However, other crops are also prominent, such as wheat, cassava, rice, banana, and oil palm. Processing these crops generates large amounts of solid residues, including in‐field or agricultural residues (straw, leaves, and foliage) and agro‐industrial processing residues (bagasse, bunches, and shells) with diverse composition and volume (Table ) …”

South America is a pivotal supplier of agricultural commodities for a growing world population. This large-scale production generates a substantial amount of lignocellulosic residue. Inadequate disposal of this material can lead to putrefaction and leaching, and can attract insects and rodents. Solid residues can be treated by incineration or composting -both causing greenhouse gas emissions. Biotransformation of lignocellulosic residues into valuable products has been proposed as a more sophisticated alternative to burning. However, pretreatment steps are necessary to obtain fermentable sugars for biological or thermochemical transformation into value-added products. In this review, we noted trends in lignocellulosic biomass generation and potential uses, with special attention to the procedures necessary for the generation of fermented products and bio-oil. This survey pointed out that sugarcane bagasse, cereal straws, bananas, and oil-palm biomass can generate about 900 million tonnes of biomass by 2025. Based on production data from several researchers it was estimated that these raw materials have the potential for annual production of more than 550 million tonnes of fermentable sugars (i.e., glucose and xylose), 670 million tonnes of bio-oil, or 4000 TWh of thermal energy. We describe procedures and strategies for the conversion of these residues to produce higher value-added biomolecules and to promote more sustainable application of lignocellulosic biomass

“…Secara nasional data dari Direktorat Jenderal Perkebunan (2016) menunjukkan bahwa limbah TKKS setara dengan 7.118.254,2 ton/tahun. Jumlah tersebut telah digunakan untuk mulsa, bahan bakar (Ninduangdee et al, 2015), bioetanol (Ishola, Isroi, & Taherzadeh, 2014;Sahari, Sapuan, Zainudin, & Maleque, 2013), etanol (Al-Oqla, Sapuan, Ishak, & Nuraini, 2015, senyawa aromatik (Lee, Lee, Ha, Kim, & Suh, 2015) dan papan partikel, namun persentase serapannya belum optimal. Kunjungan penulis ke beberapa industri pengolah kelapa sawit menunjukkan masih banyak ditemukan limbah TKKS di pabrik-pabrik minyak kelapa sawit yang siap dibuang begitu saja di lingkungan perkebunan.…”

Nowadays binderless particleboards have chance to be developed to replace particleboard with synthetic adhesive. The objectve of this research is to determine the quality of particleboards made from oil palm empty fruit bunches (OPEFB) and pine bark waste. The material composition of particleboard consist of 70% OPEFB and 30% pine bark powder with a moisture content of 5−6%. The fiber length of OPEFB is 0.1−2.0 cm and the pine bark particle sizes used to produce particleboard which passed through 30, 40, and 50 meshes. Four variations of pressing time are applied to produce particleboard i.e 10, 15, 20 and 25 minutes. Quality assesments were undergone using the Indonesian standard for particleboard product: SNI 03-2105-2006. Results showed that the best pressing time for making particleboards using OPEFB and pine bark is 20−25 minutes. The best MOR and IB are obtained from particleboard produced from oil palm fruit empty bunches with the particle size of 50 mesh. In this condition, except for MOE, the density, moisture content, MOR and IB meet the SNI requirements for particleboard. ABSTRAK Papan partikel tanpa perekat sintetis memiliki peluang untuk dikembangkan menggantikan produk serupa dengan perekat sintetis. Pemanfaatan tandan kosong kelapa sawit (TKKS) dan kulit tusam sebagai papan partikel merupakan hal yang menarik dan belum banyak diteliti. Penelitian ini bertujuan untuk memperoleh papan partikel yang memenuhi standar SNI 03-2105-2006. Komposisi papan partikel adalah 70% TKKS dan 30% kulit tusam, panjang serat TKKS 0,1−2,0 cm dan kadar air 5−6%. Variasi ukuran partikel kulit tusam adalah lolos saringan 30, 40, dan 50 mesh. Papan partikel dibuat dengan empat variasi waktu kempa panas yaitu 10, 15, 20 dan 25 menit. Hasil pengujian menunjukkan bahwa waktu kempa panas 20−25 menit merupakan waktu terbaik untuk pembuatan papan partikel dari tandan kosong kelapa sawit dan kulit tusam. Pada produk papan partikel yang dibuat dengan ukuran partikel kulit tusam 50 mesh diperoleh sifat fisik dan mekanik yang sebagian besar memenuhi SNI 03-2105-2006 untuk papan partikel kerapatan sedang tipe 8, kecuali sifat mekanik MOE belum memenuhi syarat.
