“…It is undoubtable that tunable carbon-based materials with different physical forms are novel catalyst supports that cannot be ignored, especially Pt-based catalysts. The influence of diverse catalysts such as Pt/C, Pd/C, Co-Mo, Pd/Al 2 O 3 and Pd/ZSM-5 was studied in rapeseed oil [33]. When using noble metal catalysts (Pd, Pt) on active carbon, the highest heating value and the lowest acid value of the products can be achieved, and Pt/C was the most potential catalyst for the production of hydrogenation cracking oil after process optimizations.…”

In order to cope with the shortage of non-renewable energy and the increasingly environmental pollution, sustainable vegetable oils, as competitive alternatives, have widely been held in the good graces of the researchers. Vegetable oils are suitable for a wide range of applications such as biofuels and biodiesel. However, the development of vegetable oils is limited due to the characteristics of unsatisfactory oxidation stability and poor cold-flow properties. Chemical modification is considered as an effective solution to enhance the performance. The research progress of the chemical modification methods and applications of vegetable oils in recent years are summarized in this review. Reducing the content of carbon–carbon double bonds and increasing the degree of saturation are the keys to improve the physicochemical properties of vegetable oils. The prospects for the development direction and challenges of vegetable oils are proposed. Future research may focus on the use of multifunctional catalysts to optimize reaction conditions or to introduce active groups with lubricating properties in epoxidation reactions and explore the combination of chemical and auxiliary methods.

“…The verification of the reduced hydrogen demand confirms the expected cost-reducing benefit of the two-step approach of this project. Further intensive re-search on CVO hydrotreating has been done at HAW Hamburg, applying the inno-vative reaction concept of reactive stripping, showing that standard hydrotreating catalysts are suitable (Sievers, 2013;Sievers et al, 2014;Baldauf et al, 2014;Bal-dauf et al, 2016;Baldauf, 2016;Baldauf et al, 2017). In these investigations, the mode of hydrotreating processing was gradually transferred from batch operation via semi-continuous operation to fully continuous operation (Baldauf, 2016).…”

The HAW Hamburg has developed an innovative reactive distillation technique, called READiTM process, in cooperation with the partner company Nexxoil. This process, a combination of non-catalytic thermal cracking and deoxygenation, of-fers the chance to convert a wide range of waste based raw materials into bio-oils. Characteristics of these bio-oils are low viscosity and low oxygen content. Due to that, they can be processed into liquid hydrocarbons as a basis for drop-in fuel production with comparatively little effort by hydrotreating. In the current READ-iTM-PtL project such a two-step approach of READiTM process (1st step) and hy-drotreating (2nd step) is applied to use cooking oil (UCO). In this case, the inter-mediate bio-oil is called CVO (Cracked Vegetable Oil); the final hydrotreated product is called HCVO (Hydrotreated Cracked Vegetable Oil). Within this project a technical prototype plant with a capacity of 2 tons per week is to be built and operated.
