“…Among renewables, biomass energy shares the largest contribution (9%) and is used as a raw material for the production of heat, power, and transport biofuels [1]. In particular, biomass can be transformed into first generation biofuels such as bioethanol (from sugar cane and corn) and biodiesel (from vegetable oils), through well-established technologies [2], but also into second generation biofuels (from non-edible feedstocks like lignocellulosic biomass, energy crops, algae, and waste materials) by means of emergent methodologies like fast pyrolysis coupled with catalytic hydrodeoxygenation (HDO) [3][4][5][6].…”

ZnO/Ionic Liquid Catalyzed Biodiesel Production from Renewable and Waste Lipids as Feedstocks

A new protocol for biodiesel production is proposed, based on a binary ZnO/TBAI (TBAI = tetrabutylammonium iodide) catalytic system. Zinc oxide acts as a heterogeneous, bifunctional Lewis acid/base catalyst, while TBAI plays the role of phase transfer agent. Being composed by the bulk form powders, the whole catalyst system proved to be easy to use, without requiring nano-structuration or tedious and costly preparation or pre-activation procedures. In addition, due to the amphoteric properties of ZnO, the catalyst can simultaneously promote transesterification and esterification processes, thus becoming applicable to common vegetable oils (e.g., soybean, jatropha, linseed, etc.) and animal fats (lard and fish oil), but also to waste lipids such as cooking oils (WCOs), highly acidic lipids from oil industry processing, and lipid fractions of municipal sewage sludge. Reusability of the catalyst system together with kinetic (Ea) and thermodynamic parameters of activation (ΔG‡ and ΔH‡) are also studied for transesterification reaction.

“…Carbonates have also been studied to understand the effect of basic catalysts on plastic waste conversion. [138][139][140]240] However, carbonates are prone to decomposition under thermal treatment and will form oxide compounds (XO, X = metal) and CO 2 . [139] Despite the thermal instability, carbonates have been found to increase the rate of plastic degradation, reduce operational temperature, and reduce residence time.…”

“…Polypropylene has required lower activation energy than that of polyethylene [39] From the several practices, it has been concluded that the material of HDPE could be successfully degraded to gasoline and diesel fractionate hydrocarbon fuels in a suitable process conditions with different catalyst. Sing et al [27] conducted the pyrolysis process with HDPE virgin plastic waste with 5%wt of COCO3 catalyst in a borosil glass reactor at a temperature of 395 o C. It has been found that the above process extracted 92 % and 91% liquid fuel obtained from virgin and waste HDPE plastics and also found that the virgin plastic are gained slightly more oil over the waste plastic. In addition, he found that the absent of impurities will help to increase the oil yield and more conversion of gases into liquid.…”

Sing et al [27] has catalytic pyrolysis of waste and virgin HDPE material with catalyst cobalt corbonate (CoCO3) in borosil glass reactor temperature of 20 -395 o C with duration of 4 Hour 20 minutes. In that results studied shows that the yield of liquid oil is about 80 -92% for virgin HDPE and 79-91% for waste HDPE .…”

The rapid growth of the world population which leads to increase demand of plastic in many sectors such as construction, medical, engineering applications, automotive, aerospace and many food industries for packing purpose. These rapid populations of plastic create some serious issues to the environment and living beings. The plastics are non- degradable and emit poisonous gases during burning. In recent years, many researches being conducted to resolve the disposal issues of waste plastics and trying to convert it into useful products. The plastic is a material consists of any wide range of synthetic or semi-synthetic organic compounds, which are long molecules built around chains of carbon and hydrogen atoms. The conversion of waste plastics to hydrocarbon (HC) fuel is an effective idea for disposing of waste plastics. It will be controlled plastic population and fulfill the needs of petroleum fuel in the future. As per the survey, the fossil fuels run out earlier in 2088 due to drastic growth of automobiles and high production cost. The waste plastic contains hydrocarbon with calorific value of 41- 47MJ and it is almost equal to the calorific value of fossil fuels. There are many methods being used to extract liquid HC fuel from waste plastics and it has been reviewed elaborately in this paper. It also reviews composition of various plastics like polyethylene terephthalate, high density polyethylene, low density polyethylene, polyvinyl chloride and polypropylene polystyrene and analyse their properties. In addition, it includes the selection of plastic and catalyst for extraction process, research gap in the existing extraction methods and the effect temperature and process timing on oil yield.
