Biodiesel vs. petroleum diesel pollutants... does biodiesel produce fewer pollutants?

Question

I understand that the primary drawback to diesel are the pollutants (particulates and NOx ?); and, although 'bottom line' pollution (i.e. greater energy extracted per gallon/fuel efficiency, etc.) may be 'better' than gasoline engines, is there a significant difference, regarding pollutants, between petro-diesel and biodiesel?

Answer 1

Not really and the pollutant of NO2 is not so bad. Mother nature does it every time it lightening's. It is the heat but will wash out of the atmosphere with rain. Some places along the highway u see dead trees and they say it is the acid rain wrong it is that NO2 is a fertilizer and what happens to a plant with too much fertilizer and not enough rain.

Answer 2

Yes, normal diesel pollutes with NOx, COx, SOx, HxS, CxHy and particulate matter, while biodisel produces mainly COx.

Answer 3

Burning biodiesel produces an identical CO2 that replaced into used to offer the biodiesel interior the 1st place so it is not any longer a depend of what pollution it produces however the reality that it is a shorter cycle of the products of the reaction decrease back into the gas. Fossil sourced fuels are hydrocarbons that have been sequestered for hundreds of thousands of years so the pollution that are produced via burning fossil fuels are those that weren't interior the ambience for hundreds of thousands of years subsequently a internet strengthen of CO2, H2O and a internet decrease of O2 (The C and H is from the fossil gas or the bio gas however the O is from the air). With fossil fuels, we ought to attend hundreds of thousands of years till now the pollution land up decrease back as gas returned. sure, organic and organic fuels are notoriously inefficient to offer, photosynthesis has a theoretical performance decrease of 6.6% and maximum plant life function properly below a million% performance and biodiesel and ethanol production in elementary terms makes use of the nutrition bearing component of the plant. yet who says the source ought to be organic and organic, we are able to surely synthesize linear hydrocarbons right now from CO2 and H2O via utilising photograph voltaic potential as verified via Sandia Labs CR5 reactor. Photovoltaics have reached efficiencies of 40 two.8% so we are able to surely outdo nature yet our photograph voltaic panels do no longer enhance on timber. synthetic fuels synthesized from gasification of biomass like trash and dried sewage can surely be carbon destructive besides as being carbon independent so our modern-day autos can surely help freshen up our ecosystem in spite of the pollution popping out their exhaust pipe. you won't be able to easily look at what's popping out of the exhaust pipe yet the place the gas is coming from.
