The Catalysed Transformation of Vegetable Oils or Animal Fats to Biofuels and Bio-Lubricants: A Review

Round 1

Reviewer 1 Report

Dear Editor,

 

The manuscript by Martin Hajek et al. summarizes an overview of the vegetable oils and animal fats as a promising resource of reusable energy. The review provides an overview of the transformation of oils/fats into biofuels and biolubricants. The manuscript is well written and organized. I think the manuscript should be attractive for a selected group of readers of catalysts and could fit on the scope of the journal. However, minor things should be addressed before acceptance:

 

Introduction

Line 74-75. It should be indicated all the sources for obtaining renewable energy. For example, I miss geothermal, oceans, hydrogen, etc.

Reference 5, is not properly referenced, could be improved.

Line 113,  “The consumption in also USA increasing” seems inconsistent with the text. It should be revised to clarify the meaning.

Main text

Table 4 is a bit confusing when trying to discern advantages and disadvantages of each catalyst. The table should be modified so that each item is clearly delimited.

 

Line 661 indicates a list of companies that have developed commercial triglycerides. I do not see the interest for readers to mention these companies. Also, I think there are many more of there even more important which could be added. I recommend deleting it from the text.

 

Titles on the paragraphs 5.1, 5.2 and 5.3 are very general. They could be improved to include more information about the section.

 

References

References format should be revised, there are many typos and format is not correct.

Line 74-75. It should be indicated all the sources for obtaining renewable energy. For example, I miss geothermal, oceans, hydrogen, etc.

The other sources of renewable energy were added.

 

Reference 5, is not properly referenced, could be improved.

The reference 5 was replaced by more appropriate reference.

 

Line 113,  “The consumption in also USA increasing” seems inconsistent with the text. It should be revised to clarify the meaning.

The sentence was rewritten.

 

Main text

Table 4 is a bit confusing when trying to discern advantages and disadvantages of each catalyst. The table should be modified so that each item is clearly delimited.

Table 4 was modified so that each advantage or disadvantage can be clearly seen.

 

Line 661 indicates a list of companies that have developed commercial triglycerides. I do not see the interest for readers to mention these companies. Also, I think there are many more of there even more important which could be added. I recommend deleting it from the text.

In line with the reviewer’s comment, the names of the companies have been deleted.

 

Titles on the paragraphs 5.1, 5.2 and 5.3 are very general. They could be improved to include more information about the section.

The titles of paragraphs 5.1, 5.2 and 5.3 have been edited to include more information about the corresponding section.

Reviewer 2 Report

The authors have summarized the entire process of biodiesel and Green diesel production. Its significance and comparison to Fossil diesel is clearly presented. Though there are number of reviews regarding green diesel topic, this review by Martin et al. would be a good addition to the list.

Comments:

In the introduction section: Line 93 for example: The authors mention the problems associated with first generation and second generation biofuels, but i encourage them to describe the problems.
