“…5, it can be seen that the crude palm oil of oil palm loose fruits (LF) contains palmitic acid. Palmitic acid has a carbon atom similar to that of crude oil, so the resulted crude palm oil has the potential to be used as biofuel [8,9]. Figure 6a shows that the palmitic acid content increases with the increase in the delay time of the oil palm loose fruits (LF) processing.…”

Generally the palm loose fruits (LF) that have passed the processing time are considered as solid waste. In this study, the potential of palm loose fruits (LF) will be investigated. Mechanical extraction to obtain crude palm oil (CPO) from palm loose fruits (LF) will be carried out. Before enter the extraction process, oil palm loose fruits (LF) will be softened by heating using steaming or pressure steaming (autoclaving). The oil palm loose fruits (LF) that have passed the processing delay of 4, 8 and 12 days will be characterized and investigated related to the composition of the mesocarp, seeds and yields, both by steaming and autoclaving. It was found that the composition of mesocarp of oil palm loose fruits (LF) at different processing delay by steaming or autoclaving process was ± 55% and the yield of oil (CPO) was around 15.3 -16.64%. The results also showed that autoclaving will give significantly more yields than steaming when the oil palm loose fruits (LF) had a 12-day delay in processing. The composition of the seeds or kernels of oil palm loose fruits (LF) was around 45%. Seeds known as kernels which can be processed to produce crude palm kernel oil (CPKO), further could offer the added economic value of palm loose fruits (LF). In addition, this study found that CPO of oil palm loose fruits (LF) contain palmitic acid, while palmitic acid increased with increasing processing delay of palm loose fruits. The palmitic acid content increases due to the hydrolysis process of the palm loose fruits. Palmitic acid is a type of saturated fatty acid that has similarities with hydrocarbon compounds found in petroleum, so it can be determined that oil palm loose fruits (LF) that have passed the processing time up to 12 days still have potential as a source of biofuels.

Lignosulfonate-Based Ionic Liquids as Asphaltene Dispersants

2023

Asphaltenes are recognized as being troublesome from upstream to downstream in the oil industry due to their tendency to precipitate and self-associate. Their extraction from asphaltenic crude oil for a cost-effective refining process is a crucial and critical challenge in the oil and gas sector. Lignosulfonate (LS), as a by-product of the wood pulping process in the papermaking industry, is a highly available and underutilized feedstock. This study aimed to synthesize novel LS-based ionic liquids (ILs) by reacting lignosulfonate acid sodium salt [Na]2[LS] with different alkyl chains of piperidinium chloride for asphaltene dispersion. The synthesized ILs, 1-hexyl-1-methyl-piperidinium lignosulfonate [C6C1Pip]2[LS], 1-octyl-1-methyl-piperidinium lignosulfonate [C8C1Pip]2[LS], 1-dodecyl-1-methyl-piperidinium lignosulfonate [C12C1Pip]2[LS] and 1-hexadecyl-1-methyl-piperidinium lignosulfonate [C16C1Pip]2[LS] were characterized using FTIR-ATR and 1H NMR for functional groups and structural confirmation. The ILs depicted high thermal stability because of the presence of a long side alkyl chain and piperidinium cation following thermogravimetric analysis (TGA). Asphaltene dispersion indices (%) of ILs were tested by varying contact time, temperature and ILs concentration. The obtained indices were high for all ILs, with a dispersion index of more than 91.2% [C16C1Pip]2[LS], representing the highest dispersion at 50,000 ppm. It was able to lower asphaltene particle size diameter from 51 nm to 11 nm. The kinetic data of [C16C1Pip]2[LS] were consistent with the pseudo-second-order kinetic model. The dispersion index (%), asphaltene particle growth and the kinetic model agreed with the molecular modeling studies of the HOMO–LUMO energy of IL holds.

“…The wide sources of animal and vegetable oils provide abundant raw materials for biodiesel, and the development of biodiesel has gone through three generations. , The raw materials of the first-generation biodiesel mainly come from edible oil crops (i.e., oilseed rape, soybean, and sunflower). However, large-scale production is limited by the high costs, long production cycles, and competition for human food.…”

The second-generation biodiesel generated via deoxygenation of vegetable oils is an ideal green fuel compared to fossil fuels, and it can help address environmental pollution and the energy crisis. During the catalytic deoxygenation process of vegetable oils, the most critical core is the synthesis of catalysts with superior reaction performance. In this work, the catalyst design strategies including the selection of metal active species (non/noble metal and amorphous alloy catalysts), adjustment of coordination environment for metal active sites by metallic interstitial compounds, lattice sulfur and lattice oxygen, and regulation of the interface between metal sites and support were summarized systematically. This review is committed to providing fundamental understandings of catalytic mechanisms and insights into the catalyst design, thus guiding the catalyst synthesis for catalytic deoxygenation of vegetable oils and further boosting the industrialization process of second-generation biodiesel.
