Vehicles’ fueling by reformed hydrocarbons

Abstract

Full cycle of a vehicle fueling by purified hydrocarbons reformed by water steam would consume twice less fuel than by Internal Combustion Engine (ICE)

 

It is:

(1) The oil/NG purification after its extraction from the production wells and before transportation to consumers.

For that purpose, the oil/NG contaminants are avoided either by the aerated seawater or by its analog in a form of mineralized fresh water aerated too.

(2) The purified oil is refined by a refinery.

(3) The purified NG/liquid hydrocarbons is reformed by the water steam in excess quanyity and at high temperature creating a gaseous mix of hydrogen and carbon dioxide in moles ratio of 4 : 1, directly on-board of a vehicle.

The said steam reforming is endothermic and consumes about 210 Joules/mol.

(4) The said carbon dioxide is poisoning the most types of fuel cells, and has to be divided from hydrogen, e.g. to reform in “dry ice”, i.e. a solid form of the carbon dioxide. It consumes negligible another 25 Joules

(5) The said hydrogen is fueling an air-hydrogen fuel cell to produce electricity in quantity about 4 * 286 * 0.67 = 770 Joules for NG, and 575 Joules for oil, moving the vehicle with energy efficiency about 45 % vs. about 23% for ICE and 30% for hybride

Progressive city-car realization and powering-Updated,#1

Progressive city-car realization and powering-Updated, #1 Author: David Judbarovski, principle inventor, retired engineer, Israel judbarovski@gmail.com   Short CV: https://www.linkedin.com/in/david-judbarovski-1390944a/ Archive since 2017 yr: http://judbarovski.blogspot.be Archive since 2006 yr.: http://judbarovski.livejournal.com [3791]-3/11/2017,   My three levels’ conception of progressive transportation was disclosed in http://www.judbarovski.blogspot.co.il/2017/05/progressive-transportation-manifesto.html  (Progressive transportation manifesto, May 02. 2017). Its first level is a city-car.   Special designed city-car is a car moved electrically and equipped by very small battery as a city-grid element, and it isn’t big news now. Such cars are to be much cheaper and simpler than conventional cars and save a lot of energy. But I can suppose strictly to reject all sorts of powering them from underground, because it is energy ineffective and creates additional

Equipment for Short Take-off and Landing (E-STOL)

Equipment for Short Take-off and Landing (E-STOL) Author: David Judbarovski, systems engineering, principle inventor judbarovski@gmail.com , Linkedin Abstract My E-STOL comprises a aerodynamic resistance of quite small area (SAR), being rigid and turnable, and a water jet device (WJD), comprising high pressure water jets in corners of quadrangular frame. The SAR can be very quickly erected or downed to turn it into additional wing-kite for short gliding in the sky. The WJD provides stabilization below stall speed and serves as start support, while landing or take-off. It is very attractive for Navy aviation, because allows high cruise speed, extremely short runway, and better reliability vs. helicopter, and we can repeat approach, if taking a portion of ambient sea water, in flight by simple pails.     The water is thrust out through the jets by gases at high pressure after ignition of “liquid vigorous combustible” (LVC), e.g. stoichiometric composition of amm

Breakthrough new fuel is better than oil

Breakthrough new fuel is better than oil David Judbarovski, systems engineering, principle inventor judbarovski@gmail.com Abstract Lithium hydride being reformed by water vapor in hydrogen then by fuel cell can create 5.25 kWh electricity/ kg. LiH, vs. 3.75 kWh per kg gasoline, while that LiH needs for its recycling 10.3 kWh renewable electricity , so system energy efficiency is 50% without any harmful exhaust. For the oil, analogous technology or by burning the both are followed by the oil recycling, they are 25% energy efficient with a lot of harmful exhaust.. Really For Lithium hydride, it was evaluated by me in the article : “Breakthrough kind of electric vehicle” in https://judbarovski.blogspot.com /2022/11 , posted at Nov. 05, 2022 For the oil, it is recycled from atmospheric CO2 and hydrogen produced by the water splitting.
