“…This endothermic reaction is associated with a weight loss starting already at lower temperatures. The weight loss at 570 °C is attributed to the decomposition of Ca (OH) 2 , which is supported by the characteristic DTA peak. The presence of CaC0 3 is proved by the DTA peak at 874 °C and the release of C0 2 at the same temperature [19].…”

“…A review of it as an energy crop can be found in [1]. The research work done has shown the potential of this species for biomass production as well as the different applications of the crop produce: the lignocellulosic biomass as solid biofuel for heat or power generation and even as a substrate for paper pulping [2], and the seed oil for biodiesel. The energy and traditional applications of this crop are detailed in [3].…”

Keywords: Cynara biomass Potassium fertilisers Combustion Thermal Analysis Scanning electron microscopy Herbaceous biomass like Cynara is commonly high in potassium, chlorine and ash, which has been reported as a source of problems for combustion applications. An appropriate management of the potassium fertilisation is suggested as a way of improving the quality of the Cynara biomass for solid fuel applications. In this work a factorial experiment was designed involving two types of fertilisers, KC1 and K 2 S0 4 , and two K rates, in order to study the effect of potassium fertilisation on the composition and thermal behaviour of Cynara biomass. The results proved that the potassium content of Cynara biomass increases with the potassium fertilisation. The thermogravimetric study showed that sintering phenomena can be expected at temperatures higher than 900 °C when the crop has been highly K-fertilised, irrespective of the type of fertiliser used, KC1 or K 2 S0 4 . However, the SEM images taken of samples of the four K treatments of this experiment did not reveal signs of ash melting, although some particles with crystalline appearance appeared in the samples from highly K-fertilised treatments.

Abstract. In recent years, there has been tremendous growth of interest in the utilization of non-wood based material to support the insufficient raw materials availability for the pulp and paper industry. Therefore, this study was conducted to investigate the characteristics of 120 gsm linerboard and corrugated medium paper made from unbeaten durian rinds chemimechanical (CMP) pulp. The linerboard and corrugated medium paper were prepared and tested according to Malaysian Standards / International Organization for Standardization (MS ISO) and Technical Association of the Pulp and Paper Industry (TAPPI) standard methods. Based on the burst index (2.03 kPa.m 2 /g), RCT (1.97 N.m 2 /g) and CMT (129N), the linerboard and corrugated medium from CMP durian rind pulp have shown a good potential as an alternative raw material for papermaking and comparable with other types of wood and nonwood based papers as well as current commercial papers.

“…There are many reported studies which investigate the use of annual plants or/and agricultural wastes as a new alternative sources to produce fibers [2][3][4][5][6][7]. These strategies were already applied in various countries for an example: Portugal [8][9][10], India [11,12], Malaysia [13,14], Iran [15] or Tunisia [2] and so on.…”

Synthesis and Characterization of Carboxymethyl Cellulose from Tunisian Vine Stem: Study of Water Absorption and Retention Capacities

et al. 2014

The aim of this work was to study the effect of the degree of substitution (DS) and the purity of sodium carboxymethyl cellulose (CMCNa) prepared from Tunisian vine stem on the absorption and retention of water. Vine stem was first delignified using souda-anthraquione, then bleached and finally chemically modified, in order to synthesize different CMCNa derivatives. The carboxymethylation reaction was carried out in presence of NaOH (40 %) and monochloroacetic acid (ClCH 2 COOH), in n-butanol as a reaction solvent. The obtained CMCNa derivatives were characterized using different tools such as the DS, Fourier transforms IR techniques, CP-MAS 13 C-NMR, the exchange capacity as well as the determination of modification reaction yield. The performance of the prepared derivatives in term of absorption capacities and retention capacities was established. The performance of CMCNa derivatives was compared with that achieved by commercial counterparts and it was concluded that the prepared ones exerted higher efficiency.
