“…23,[240][241][242][243] Nevertheless, since only the lignin fraction of the biomass is aromatic in nature, lignin represents the main precursor for the formation of aromatic and PAH-type compounds. 243,244 The formation of tar during the gasification process results in a significant decrease in efficiency and may cause serious problems, such as blocking and fouling in downstream equipment. In addition, tar is often responsible for serious coke deposition on the downstream catalysts provoking a rapid deactivation if the synthesis gas is utilized for production of methanol and Fischer-Tropsch liquids.…”

Recent advances on the utilization of layered double hydroxides (LDHs) and related heterogeneous catalysts in a lignocellulosic-feedstock biorefinery scheme

Layered double hydroxides (LDHs) and derived materials have been widely used as heterogeneous catalysts for different types of reactions either in gas or in liquid phase. Among these processes, the valorization/upgrading of lignocellulosic biomass and derived molecules have attracted enormous attention because it constitutes a pivotal axis in the transition from an economic model based on fossil resources to one based on renewable biomass resources with preference for biomass waste streams. Proof of this is the increasing amount of literature reports regarding the rational design and implementation of LDHs and related materials in catalytic processes such as: depolymerization, hydrogenation, selective oxidations, and C-C coupling reactions, among others, where biomass-derived compounds are used. The major aim of this contribution is to situate the most recent advances on the implementation of these types of catalysts into a lignocellulosic-feedstock biorefinery scheme, highlighting the versatility of LDHs and derived materials as multifunctional, tunable, cheap and easy to produce heterogeneous catalysts.

“…Lebih dari 400 senyawa yang telah teridentifikasi, dimana komponen senyawa tersebut ditemukan tergantung dari jenis kayu, umur tanaman sumber kayu, dan kondisi pertumbuhan kayu seperti iklim dan tanah [8]. Contohnya, tar yang dihasilkan dari selulosa adalah furan dan aldehida molekul kecil, tar yang dihasilkan dari hemiselulosa adalah asam asetat, dan yang dihasilkan dari lignin adalah furfural dan fenol [9]. Untuk menganalisa senyawa-senyawa tar yang dihasilkan oleh pirolisis ini digunakan alat uji gas chromatography-mass spectra (GC-MS).…”

This study indentified the tar yield of pyrolysis of mahogany wood. The produced tar would be analyzed using GC-MS (Gas Chromatograph-Mass Spectrometry) to understand their chemical properties affected by temperature pyrolysis. It would be identified if the elements are flammable matters or not. It is due to the fact that the yields of pyrolysis desire the flammable matters as much as possible as a biofuel. The experiment was conducted at a fixed bed reactor. The needle particle of mahogany wood was used as the pyrolysis feedstock having weight of 200 gram, sizing of mesh 20 m, and containing 2% moisture content. The variations of pyrolysis temperature influencing the mahogany wood decompositions are 250°C, 350°C, 450°C, 500°C , 600°C, 700°C and 800°C. The pyrolysis was carried out during 3 hours almost without Oxygen. The result of tar yields show that a getting higher of the pyrolysis temperature caused the volume and mass of tar formed by condensation in cold trap would increase up to 500°C and then decrease. The increasing of tar yields would also increase some acetic acid compounds and reach a peak at 350°C in which the acetic acid compound is a flammable substance. From the GC-MS results, it was also presented that at any pyrolysis temperatures, the amount of the flammable tar compounds were higher than the unflammable one. It can be interpreted that the tar yield is very potential as liquid fuel (bio-oil) because the main elements of tar is acetic acid having flash point (flash point) equal to 39°C.
