Animal fats valorization to green transportations fuels: From concept to industrially relevant scale validation.

The potential of animal fats hydroconversion is experimentally investigated and validated in industrially relevant scale via the production of 100 L of transportation fuels. The experimental testing has indicated that mild hydrotreatment conditions are associated with low hydrogen consumption without significantly penalties in product quality. The optimal operating conditions (pressure of 6.

Oxidative stability of waste cooking oil and white diesel upon storage at room temperature.

Renewable diesel fuels are alternative fuels produced from vegetable oils or animal fats. Catalytic hydrotreating of waste cooking oil (WCO) was carried out at pilot-plant scale and a paraffinic diesel, called "white" diesel was obtained. The white diesel and WCO samples were stored for one year at room temperature under normal atmospheric conditions, but not exposed to sunlight.

Hydrotreating of waste cooking oil for biodiesel production. Part II: effect of temperature on hydrocarbon composition.

This study focuses on the use of waste cooking oil (WCO) as the main feedstock for hydrotreatment to evaluate the effect of temperature on the product hydrocarbon composition. A qualitative analysis was initially performed using a GC x GC-TOFMS indicating the presence of mainly paraffins of the C15-C18 range. A quantitative analysis was also performed via a GC-FID, which gave both n-paraffins and iso-paraffins in the range of C8-C29.

Hydrotreating of waste cooking oil for biodiesel production. Part I: Effect of temperature on product yields and heteroatom removal.

Hydrotreating of waste cooking oil (WCO) was studied as a process for biofuels production. The hydrotreatment temperature is the most dominant operating parameter which defines catalyst performance as well as catalyst life. In this analysis, a hydrotreating temperature range of 330-398 degrees C was explored via a series of five experiments (330, 350, 370, 385 and 398 degrees C).

Hydrocracking of used cooking oil for biofuels production.

Hydrocracking of used cooking oil is studied as a potential process for biofuels production. In this work several parameters are considered for evaluating the effectiveness of this technology, including hydrocracking temperature, liquid hourly space velocity (LHSV) and days on stream (DOS). Conversion and total biofuels production is favored by increasing temperature and decreasing LHSV.

Hydrocracking of vacuum gas oil-vegetable oil mixtures for biofuels production.

Hydrocracking of vacuum gas oil (VGO)--vegetable oil mixtures is a prominent process for the production of biofuels. In this work both pre-hydrotreated and non-hydrotreated VGO are assessed whether they are suitable fossil components in a VGO-vegetable oil mixture as feed-stocks to a hydrocracking process. This assessment indicates the necessity of a VGO pre-hydrotreated step prior to hydrocracking the VGO-vegetable oil mixture.
