The scientific community and public are expressing concerns regarding global stewardship and sustainability. In the chemical industry, sustainability efforts focus on improved energy and capital intensity, otherwise known as process intensification. A European Roadmap for Process Intensification was developed in 2007, outlining technologies that may be used to intensify chemical processes. 1 In 2017, the American Institute of Chemical Engineers partnered with the United States Department of Energy to form the RAPID Manufacturing Institute. 2 The goal of RAPID is to promote and drive the adoption of process intensification principles in energy-intensive industries.These initiatives sparked the exploration of new process intensification technologies. Much of the current research investigates the

“…The composition of the biodiesel waste was determined by using a standard method [4][5][6][7] in order to predict the cracking products. The analysis revealed a 54.5% matter organic non-glycerol (MONG) content, which consisted of mainly methyl ester molecules, 37.2% glycerol, 6.5% ash, and 1.8% water content.…”

“…Glycerol, a polyol molecule containing three hydroxyl groups, is an important chemical reactant for various applications, such as in the food, cosmetic and pharmaceutical industries [1,2]. However, glycerol can also be converted to valuable products as hydrocarbon molecules and synthesis gas [3][4][5][6][7]. Techniques used for the transformation of glycerol include hydrogenolysis [8][9][10][11][12], dehydration [13][14][15][16], esterification [17,18], carboxylation [19], catalytic cracking [20,21], and other reactions [22,23].…”

Catalytic Cracking of Biodiesel Waste Using Metal Supported SBA-15 Mesoporous Catalysts

et al. 2019

Palladium (Pd) and aluminium (Al) supported on SBA-15 were prepared as catalysts for cracking biodiesel waste from biodiesel production. Mesoporous silica SBA-15 was first synthesized by a hydrothermal method and then loaded with Al or Pd particles were loaded using postsynthesis or aqueous wet impregnation methods, respectively. The physical properties of the catalysts were characterized by X-ray diffraction (XRD), nitrogen (N2) adsorption, scanning electron microscopy (SEM), and transmission electron microscopy (TEM) analyses. The catalytic cracking performance of biodiesel waste was evaluated at reaction temperatures above 400 °C under a N2 atmosphere in a batch reactor for 40 min in comparison with that for pure glycerol, where the conversion of biodiesel waste reached 86.8% with 10 wt% Pd-SBA-15 at 650 °C. The product types depended on whether the starting material was pure glycerol or biodiesel waste. The main gaseous products were carbon monoxide as synthesis gas, carbon dioxide, and 1,3-butadiene. Additionally, 2-cyclopenten-1-one and 2-propen-1-ol were major products in the liquid fraction, which can be used in pharmaceuticals and as a flame retardant, respectively.

“…There are two kinds of reaction model: one is the empirical model and the other is the mechanism model. The empirical model contains the statistical response surface methodology [22] and sensitivity equation [23], lumping method with parameters estimation [24], and the artificial intelligence model [25]. The details of the adopted free-radical reaction network is showed in Table 2.…”

The Kumar model as a molecular model has achieved successful application. However, only 22 reactions limit its veracity and adaptability for feedstocks. A series of models with different degrees of integration of the free radical model and the molecular model has been proposed to enhance feedstock adaptability and simulation accuracy. An improved search engine algorithm, namely Improved PageRank (IPR), is provided and applied to calculate the importance of substances in Kumar model to screen the free-radical reaction network for efficient model selection. A methodology of optimal structure and model parameters chosen is applied to the target to improve the adaptability of the material and the accuracy of the model. Then, two cases with different feedstocks are demonstrated with industrial data to verify the correctness of the proposed approach and its wide feedstock adaptability. The proposed model demonstrates good performance: (1) The mean relative errors (MRE) of the K-R (Kumar and free-radical) model have reached an order of magnitude less than 0.1% compared with 5% in the Kumar model. Further, (2) the K-R model can be implemented to model some feedstocks which Kumar model can’t simulate successfully. The K-R model can be applied in simulation of extensive feedstocks with high accuracy.
