“…This is most likely due to the higher amount of Na available to catalyze the transesterification process which in turn produces a higher amount of biodiesel. The same increasing trends were also obtained in previous researches in which biodiesel was produced from N. oculata and C. vulgaris and various amount of loadings were used in heterogeneous catalysts [6,7,8,9]. …”

Abstract. Microalgae are promising sources of biofuel due to its production capacity of lipid that can be utilized as raw material for biodiesel production, especially Nannochloropsis oculata and Chlorella vulgaris. The lipid produced can be converted into biodiesel through transesterification reaction using homogenous or heterogeneous catalysts. Heterogeneous catalysts are more advantageous than homogeneous catalysts due to its solid form that eases the separation of catalysts from the products. In this research, NaOH/zeolite heterogeneous catalyst is utilized with varying Na loadings in the zeolite to observe its effect towards the yield of biodiesel produced from N. oculata and C. vulgaris. The best result was obtained with Na loading concentration of 20.5%. The biodiesel yields obtained from the lipids are 83.5% from N. oculata and 98% from C. vulgaris. The biodiesels contain 47.15% of saturated fatty acid methyl esters from N. oculata and 56.41% from C. vulgaris.

“…The results of different catalyst to oil loadings on the FAME yield, however, shows the yield of FAME was almost doubled (see Figure 12(B)) when the (trans)esterification process was set at 9hrs of reaction time, 2wt% of nanocatalyst to UCO, 6:1 methanol to oil mole ratio, 65°C reaction temperature, 600 RPM of agitation rate, 0.14% moisture and <2.0% of FFA in raw material. This was attributed to the fact that the number of A c c e p t e d M a n u s c r i p t 16 active sites were increasing with an increase the catalyst concentration in the reaction system requiring a shorter time to reach the equalibrium [58]. Furthermore, the yield of FAME further increased from 14.92% to 38.7% with an increase in the nano-catalyst loading from 2wt% to 4.5wt% of UCO.…”

Highlights• A novel, efficient and recyclable mesoporous TiO 2 /PrSO 3 H solid acid nano-catalyst was synthesised.• We examined the catalytic activity, stability and reusability of synthesised mesoporous TiO 2 /PrSO 3 H.• The FAME yield from UCO was 98.3% under optimum process conditions.• Synthesised biodiesel from UCO satisfied ASTM D6751 and EN 14214 standards. ABSTRACTA novel, efficient and recyclable mesoporous TiO 2 /PrSO 3 H solid acid nano-catalyst was synthesised by the post-synthetic grafting of propyl sulfonic acid groups onto a mixed phase of a TiO 2 support. The synthesised nano-catalyst was characterised using FTIR, SEM, TEM, XPS, N 2 adsorption-desorption isotherms, XRD, DSC, TGA, and CHNS analysis. The percentage of loading for propyl sulfonic acid on the TiO 2 support was calculated using CHNS analysis and TGA. The catalytic performance of TiO 2 /PrSO 3 H on the production of the fatty acid methyl esters (FAME) via simultaneous esterification and transesterification reactions from used cooking oil (UCO) has been studied. The effects of different process parameters showed that 98.3% of FAME can be obtained after 9 hrs of reaction time with 1:15 molar ratio of oil to methanol, 60°C reaction temperature and 4.5 wt% catalyst loading. It was also found that the one-pot post-surface functionalisation strategy with hydrophilic functional groups (-SO 3 H) enhanced the acid strengths of the nano-catalyst providing more acid sites for the reactants, and improving the accessibility of methanol to the

“…O rendimento obtido é extremamente baixo (28% de éster metílico). (LI et al, 2011) No presente invento diz respeito a simultaneidade da extração e produção de biodiesel, que promove maior seletividade e qualidade do material graxo, pois utiliza-se apenas metanol/etanol como solvente de extração, já o utilizando simultaneamente na reação de transesterificação/esterificação. Além disto, a composição da matéria prima pode ser heterogênea, não precisando de um processo anterior de tratamento e a matéria prima não entra em contato direto com a reação geradora de biodiesel, sendo assim facilmente separada e não precisando de um tratamento para a retirada do resíduo e posteriormente para o reuso do álcool e do catalisador.…”

RESUMOO biodiesel é um biocombustível importante para a matriz energética nacional é produzido de diferentes fontes oleaginosas, desempenhando papel importante na produção final do biocombustível. Diante de sua cadeia produtiva e da importância de métodos mais sustentáveis, realizou-se um estudo prospectivo sobre o processo simultâneo de produção de biodiesel visando à condensação das etapas de produção via simultaneidade de extração e respectiva conversão a partir de resíduos agroindustriais oleaginosos. Além disso, tem-se como objeto de estudo a utilização de catálise heterogênea ao sistema, agregando facilidades na separação do produto e do meio catalítico. Neste nicho de pesquisa e desenvolvimento de métodos alternativos para o setor do biodiesel encontram-se poucas patentes e artigos, sendo em sua maioria evidenciados processos em escala laboratorial. Sendo assim, tal tecnologia merece atenção, investimento e desenvolvimento para seu escalonamento, tendo em vista agregar diversos benefícios ao setor, desde a matéria-prima até o processo e distribuição.Palavras-chave: Biodiesel.

PROSPECTIVE STUDY ON THE PROCESS OF EXTRACTION OF AGRICULTURAL WASTE GRAIN MATERIAL WITH SIMULTANEOUS BIODIESEL PRODUCTION ABSTRACTBiodiesel is an important biofuel for the national energy matrix is produced from different oil sources, playing an important role in the final production of biofuel. In view of its production chain and the importance of more sustainable methods, a prospective study was carried out on the simultaneous production process of biodiesel, aiming at the condensation of the production stages through the simultaneity of extraction and respective conversion from agro-industrial oleaginous residues. In addition, the object of study is the use of heterogeneous catalysis to the system, adding facilities in the separation of the product and the catalytic medium. In this niche of research and development of alternative methods for the biodiesel sector are few patents and articles, being mostly evidenced processes in laboratory scale. Therefore, such technology deserves attention, investment and development for its scheduling, aiming to add several benefits to the sector, from the raw material to the process and distribution.
