Biodiesel production from hybrid non-edible oil using bio-support beads immobilized with lipase from Pseudomonas cepacia

The rising demands of fuel and petrochemical fuels that have harmful gas emissions are encouraging researchers to develop green fuels, especially biodiesel. Whereas the substantial restriction for utilizing biodiesel as a replacement fuel is poor cold flow properties. This research aimed to consider the synchronic improvement of canola biodiesel-diesel-alcohols mixture with low-temperature performance and diesel engine parameters. The simplex lattice mixture design method was applied to optimize, statistically analyze, and design fuel-blend experiments. The best-fitted values via the models were verified employing analysis of variance. Optimum conditions for the cold flow properties of the ternary fuel blends were achieved at biodiesel (19.3), diesel (41.7), and alcohol (39) v/v.%, named as B19.3-Bu39. At the optimum, the best cold flow properties had a pour point and cloud point of − 22.67 and − 16.37 0C. Engine performance results revealed that increment of higher alcohols in fuel blend enhanced brake specific fuel consumption (6.22%) and exhaust gas temperature (16.25%), while the brake thermal efficiency (4.03%) diminished. At the maximum loading, emission reductions of 13% and 49% of carbon monoxide, and 20.3% and 30.5% of unburned hydrocarbon were achieved for B19.3 and B100 (100% biodiesel). Oxidative stability of the optimum fuel blend was 10.32 h, which is satisfactory according to EN14214 standard. Results implied that the B19.3-Bu39 fuel has superior lubrication, lower emission, wear, and friction as compared to pure diesel. It can be concluded that the incorporation of higher alcohols presents a novel prospect for the simultaneous improvement of fuel cold flow properties and CI engine operability parameters.

Towards water-insensitive CO2-binding organic liquids for CO2 absorption: Effect of amines as promoter

The transesterification of Amygdalus scoparia oil to biodiesel was performed and examined through the electrolysis method in the presence of KOH/Al2O3 as a heterogeneous catalyst at room temperature. A KOH/Al2O3 as solid base catalyst was prepared through the impregnation of Al2O3 with KOH solution (concentration of 25g in 100 mL deionized water). The catalyst was analyzed using X-ray diffraction (XRD), scanning electron microscopy (SEM) and Energy-dispersive X-ray spectroscopy (EDS). The transesterification key variables such as reaction time, methanol to oil molar ratio, and catalyst weight were optimized by applying the central composite design (CCD) approach. The maximum yield of 94% was obtained at the methanol to oil ratio of 10:1, catalyst weight of 1.6 wt/v%, voltage of 10 V, a reaction time of 2.30 h, 10 wt% acetone at room temperature (25 ᵒC). The characterizations of Amygdalus scoparia oil and biodiesel were specified using a gas chromatography-mass spectrometry (GC-MS) and Fourier-transform infrared spectroscopy (FTIR) analyses.
