In this research, thermal and catalytic pyrolysis of neem seed as a non-edible feed has been investigated for the production of valuable chemicals including bio-oil, bio-char and bio-gas. The sensitivity analysis of main operating parameters of thermal pyrolysis process including temperature (350-550 °C), reaction time (30-180 min) and heating rate (10-40 °C/min) on the major products yield has been performed and the optimum operating condition to maximize the bio-oil production has been determined. The achieved results indicated that the maximum bio-oil production yield is obtained at temperature of 450 °C. The bio-oil production yield enhances with increasing the heating rate, whereas the process time in the considered range has not significant effect on the bio-oil production yield. Since the main focus of this study was catalytic upgrading of pyrolysis-derived bio-oil to valuable fuels, catalytic pyrolysis of neem seeds over industrial RFCC catalyst has been examined using different catalyst loading in the range of 10-40 wt %. It is inferred that more aromatic compounds will be generated with increasing the RFCC catalyst loading which could be attributed to the presence of Al 2 O 3 and zeolite in the catalyst structure. Also, the bio-oil and bio-gas production yields via catalytic pyrolysis process over 20 wt. % RFCC catalyst enhanced from 44.3 % to 49.5 % and 22.4 % to 27 % with increasing temperature from 350 and 450 °C, respectively.

Thermal and catalytic pyrolysis of olive pomace as a second generation of biomass for the production of valuable bio‐oil has been investigated. The achieved results indicate that the maximum bio‐oil production yield through the non‐catalytic pyrolysis process is 56% at a temperature of 500°C, with a high content of oxygenated compounds. Since the main focus of this study was the catalytic upgrading of pyrolysis‐derived bio‐oil to valuable fuels, an industrial residue fluid catalytic cracking (RFCC) catalyst has been examined using different catalyst to biomass ratios. For a catalyst to biomass ratio of 0.5, the highest bio‐oil production yield was 44 wt% at 500°C and for a catalyst to biomass ratio of 5, the highest bio‐oil yield was 39 wt% at 400°C. The obtained experimental results indicate that, although the bio‐oil production yield decreases through catalytic pyrolysis, application of RFCC catalysts reduces the oxygenated compounds as undesirable products and increases aromatic and cyclic compound content in the bio‐oil, significantly. By increasing the temperature, the production of aromatic compounds as valuable products intensifies, and this compound group is identified as the main content of the derived bio‐oil. It is inferred that RFCC catalysts are appropriate candidates for use in the pyrolysis process for developing biofuel production on an industrial scale. © 2022 Society of Chemical Industry and John Wiley & Sons, Ltd.

In recent years there has been a growing interest in the scale‐up and commercialization of lignocellulosic biorefinery. Process simulation is a crucial preliminary study, conducted at the system level, to evaluate the feasibility of industrializing biorefinery operations. Numerous research studies have been conducted on the application of process simulation in lignocellulosic biorefinery, making it essential to provide a detailed introduction to this topic. This paper summarizes two aspects of the application of process simulation in lignocellulosic biorefinery: the production of bioenergy and the production of biochemicals. The bioenergy section describes the application of process simulation to hydrochar, syngas, and bioethanol. The biochemicals section relates to the production processes for cellulose, lignin, and hemicellulose. Additionally, the research status of process simulation in biorefinery are detailed from the following aspects: physical property parameters, kinetic study, the variety of raw materials and validation. Finally, this paper discusses some advances in biorefinery process simulation. It is hoped that this paper will assist the industrialization of lignocellulosic biorefinery.
