Abstract-Experimental study was conducted to investigate the influence of the injection timing on the performance and exhaust emissions of an electronic control high-pressure common rail turbocharged direct injection diesel engine fueled with isopropanol. Diesel fuels with different amounts (0%, 5%, 10%, 15% and 20% by volume) of isopropanol were used. The results show that the isopropanol addition can significantly improve soot and CO emissions. Under the same injection timing, with the increase of isopropanol blending ratio, combustion duration shortened, brake specific fuel consumption increased, the peak of in-cylinder pressure and heat release rate of pilot-injection combustion decreased, the peak of in-cylinder pressure and heat release rate of main-injection combustion increased, THC and NOx emissions increased. With the injection timing retarded, the center of heat release rate of pilot and main injection combustion delayed, the peak of in-cylinder pressure and heat release rate of former ascended, the latter descended. Brake specific fuel consumption, CO emission, THC emission and soot emission reduced, NOx emissions increased.

“…Ca(OH)2, has been extensively used in improving biodegradability because of its low cost, high recoverability, safe handling, and minor environmental effects [49]. Song et al 2012) [50] reported that the lignin, cellulose, and hemicellulose of rice straw were significantly degraded, and the highest methane yield of 225,3 ml/g VS, was obtained with 9,81% Ca(OH)2 (w/w TS) for 5,89 day pretreatment time, and 45,12% inoculum content.…”

Abstrack -Rice straw is one of organic material that can be used for sustainable production of bioenergy and biofuels such as biogas . Out of all bioconversion technologies for biogas production, anaerobic digestion (AD) is a most cost-effective bioconversion technology that has been implemented worldwide for commercial production of electricity, heat, and compressed natural gas (CNG) from organic materials. However, the utilization of rice straw for biogas production via anaerobic digestion has not been widely adopted because the complicated structure of the plant cell wall makes it resistant to microbial attack. Pretreatment of recalcitrant rice straw is essential to achieve high biogas yield in the AD process. A number of different pretreatment techniques involving using physical pretreatment (hydrothermal and freeze), chemical pretreatment (sodium carbonate -sodium sulfite, hydrogen peroxide, NMMO, alkaline, and dilute acid) and biological pretreatment (fungal pretreatment) also combined pretretment (microwave irradiation and chemical) approaches have been investigated, but there is no report that systematically compares the performance of these pretreatment methods for application on rice straw for biogas production. This paper reviews the methods that

“…The MixAlco™ process is a version of the carboxylate platform that does not require sterilization to obtain fuels [1][2][3][4]. Using a fermentation process similar to that which occurs in the rumen of cattle, the biomass is converted to mixed acids (e.g., acetic, propionic, butyric acid).…”

Résumé -Conversion de la biomasse en combustibles hydrocarbonés au moyen du procédé MixAlco™ -Le procédé MixAlco™ convertit la biomasse en hydrocarbures (par exemple, en essence) selon les étapes génériques suivantes : prétraitement, fermentation, écumage, déshydratation, cétonisation thermique, distillation, hydrogénation, oligomérisation et saturation. Cette étude décrit la production de bioessence à partir de fumier de poulet et de papier en lambeaux, ces deux sources étant des matières premières convoitées ne nécessitant pas de prétraitement. À l'aide d'une culture mixte de microorganismes dérivés de sols marins, la biomasse a été soumise à une fermentation de manière à produire une solution aqueuse diluée de sels de carboxylates, ultérieurement écumés et séchés. Les sels séchés ont été thermiquement convertis en cétones brutes, ensuite distillées afin d'éliminer les impuretés. À l'aide du catalyseur à base de nickel de Raney, les cétones distillées ont été hydrogénées en alcools secondaires mixtes allant de C3 à C12. En utilisant le catalyseur supporté sur zéolite HZSM-5, ces alcools ont été oligomérisés en hydrocarbures dans un réacteur à écoulement piston. Enfin, ces hydrocarbures insaturés ont été hydrogénés afin de produire un mélange d'hydrocarbures pouvant être combiné à l'essence commerciale.
