<p>Lignocellulosic biomasses are promising alternative resource for bio-fuel production. But due to the recalcitrant nature of lignin and hemicellulose, necessitates an efficient pre-treatment process to improve the yield of reducing sugars and maximising the enzymatic hydrolysis efficiency. Catalysed-microwave pre-treatment may be a good alternative as compared to other methods since it can reduce the time and improve the enzymatic activity during hydrolysis. The aim of this study was to evaluate the efficiency of the catalysed-microwave based pre-treatment of lignocellulosic biomass of Camelina sativa straw (CSS) to overcome the recalcitrant nature of cellulosic biomass. The microwave-alkaline (2 % NaOH) pre-treatment of CSS at 250 W for 10 min yields maximum (~422 mg/g) total soluble sugars (TSS) production during hydrolysis. Likewise, the maximum glucose content (~294 mg/g) was measured in 2 % alkaline-microwave pre-treatment for 10 min at RT. However, slight increase in lignin degradation was observed with the increase in alkaline hydroxide concentration and microwave irradiation exposure time. The maximum degradation in lignin content (~83 %) was measured in 3 % alkaline-microwave pre-treatment for 20 min at RT. Our results suggest that the microwave-alkaline pre-treatment approach may be employed for comprehensive utilisation of CSS biomass of Camelina sativa L. cv. Calena (EC643910) for bio-fuel production.</p>

The paper reviews the topicality and practical significance of the implementation of processing technology of plastic with the purpose of obtaining raw material for manufacturing motor benzene. It is shown that this case is the advantageous strategy for the damage reduction to the environment from the oil-gas complex and usage of commercial gasoline based on the fossil hydrocarbon crude and for the utilization of plastic wastes as well. The perspective technologies of plastic processing including pyrolysis, catalytic cracking, hydrothermal liquefaction based on the bibliographic review and the recommendations on the improvement of benzene component obtained as a basis for industrial production of motor benzene are presented. In the capacity of the last ones, the implementation of alcohol mixed octane-increasing additives based on the ethanol is justified. It is shown that using alcohol not only increases octane number of the fuel, but also saves expensive hydrocarbon components, allows reducing the toxic high-octane aromatic hydrocarbons in the gasoline, improves the distribution of octane numbers by benzene fractions based on the reformat, as well as expands the crude base for fuel production due to the non-oil raw. The studies showed that adding 10 % of alcohol is the optimum concentration, as on the one hand it provides the growth of knock characteristics and phase stability of the gasoline, on the other hand does not require additional regulation of motor engine for using such fuel.
