Conceptual Design of a Batch Process for the Production of Biodiesel from High Free Fatty Acid Feedstocks

A. Mohammadi; B. Ghobadian

Volume 19, Issue 1 , March 2022, , Pages 15-32


  A batch process was developed for the production of biodiesel from high free fatty acid feedstocks. The mixed-integer nonlinear programming (MINLP) problem, caused due to applying the hierarchical procedure together with Malone’s algorithm for the conceptual design, was solved. Meanwhile, the optimum ...  Read More

Techno-Economic Optimization of a Continuous Process for the Biodiesel Production from Waste Vegetable Oils

Abbas Mohammadi; Barat Ghobadian

Volume 18, Issue 4 , December 2021, , Pages 20-35


  A continuous process was designed and optimized at a conceptual stage for the biodiesel production from waste vegetable oils. Unlike previous studies, the process was optimized taking into account the technical and economic considerations, simultaneously, to find the optimum operating conditions fort ...  Read More

Ultrasound-Assisted Biodiesel Production in microreactors

M. Basiri; M. Rahimi; H. Babaei Mohammadi

Volume 13, Issue 2 , April 2016, , Pages 22-32

  The ultrasound-assisted (UA) soybean oil methanolysis using KOH as a catalyst was studied at different reaction conditions in a microreactor. Box–Behnken experimental design, with three variables, was performed and the effects of three reaction variables i.e. reaction temperature, catalyst concentration ...  Read More

Lipase Immobilized into Novel GPTMS: TMOS Derived Sol-Gels and Its Application for Biodiesel Production from Waste Oil

M. Nikpour; M. Pazouki

Volume 13, Issue 1 , January 2016, , Pages 32-46

  In this essay, lipase from Burkholderia cepacia was immobilized into 3-glycidoxypropyltrimethoxysilane (GPTMS) and tetramethoxysilane (TMOS) derived sol-gels. GPTMS:TMOS molar ratio of 1:3 was found to yield the best result. The morphological characteristics were investigated based on SEM and BET analysis. ...  Read More

Investigation of Liquid–Liquid Two-Phase Flow Pattern in Microreactors for Biodiesel Production

M. Basiri; M. Rahimi; F. Mohammadi

Volume 12, Issue 3 , July 2015, , Pages 32-40

  "> In the present study, transesterification of soybean oil to Fatty Acid Methyl Ester (FAME) was carried out in the microreactor. The system performance was investigated in the presence of hexane as a cosolvent. Furthermore, the effect of number of micromixer’s inlets on the mixing was one ...  Read More
