Yet MARPOL Annex VI allows 2.9-4 % m/m sulfer content. If I searched correctly and I believe I did: 0.10% m/m is 1000ppm. So marpol allows up to 40,000 ppm sulfer content. Now then I got the break down on allowed by MARPOL from their web site. I got break down of 5 m/m to ppm from http://www.enginemanufacturers.org/i...uelcharter.pdf Whitelightning |

I think Volkswagon should bring back the '78 Rabbit. I got 35 MPG mixed city/highway driving (highway speeds of 70 MPH) and as good as 50 MPG at 55 MPH for a long distance. That's pretty close to matching, or bettering today's hybrids, with their more expensive batteries. > > -- > -- > --John > to email, dial "usenet" and validate > (was jclarke at eye bee em dot net) > > |
Re: Inside Toyota's Hybrid Truck
Not to rain on anyone's parade, but most of the h2 generated in North
America comes from "cracking" Nat'l gas. I do it every day. And btw, the process I use liberates more H2 than what is in the gas to start with.

Can enough be generated in that fashion to provide energy equivalent to the current consumption of gasoline? If you're getting more hydrogen out than was in the natural gas to begin with one would expect so. > Regards, > JR > > > "bearman" <noyb@home.com> wrote in message > news:p8ednRS7db9j9uTanZ2dnUVZ_u6rnZ2d@comcast.com. .. >> .... >>> Hydrogen would be nice too---but it is not cost effective to >>> release the H >>> from the "Two O".... >> >> >> I think you need to release the H2 from the O. >> >> -- >> Bearman >> >> America: Land of the free because of the brave. -- -- --John to email, dial "usenet" and validate (was jclarke at eye bee em dot net) |
Re: Inside Toyota's Hybrid Truck
OK I will try to explain this as best I can off the top of my head.
The steam used to "crack" the gas is created in a small boiler that is also gas fired. The waste gas stream from the burner contains H2 as well as other unburned hydrocarbons. These are collected as well and run thru a series of catalytic converters and stripped from the waste gas and reintroduced to the cracking chamber at moderate pressure 2-300 psig. The spent steam itself is also a small source of H2 as the flashed vapor is sent thru yet another process (semi-permeable membrane filter) as it is enroute to a collection vessel and discarded. All liquid waste is piped to our chemical waste treatment plant. The final waste gas stream is scrubbed and released from a short stack as a mix of inert gasses. This process produces roughly 10,000 cubic ft of H2/hour @ 200 psig using roughly 6,800 cubic ft of Nat'l gas/hour @ 80 psig. I will leave it to you calculate the energy available in each. I just want the H2 for other processes. There ain't no free lunch, but we are constantly working on increasing the efficiency of the process. Will this replace gasoline? I don't think so yet if you want to burn the H2 as a fuel, maybe in a few years as better methods of mobile storage and new engines are developed. It could replace gasoline now if used in a fuel cell to generate electricity. The equipment I use was originally designed as an on site source of H2 at a network of refueling stations across the country. Part of the H2 infrastructure so to speak. The H2 generating unit itself will fit in the back of a 20 ft van truck. All it needs is a source of softwater ,Nat'l gas, and electricity. It's pretty cool stuff. Regards, JR "J.

One needs to be very careful when comparing fuel sources... the energy required to convert them into a usable form has to be taken into account. |

Cracking crude oil to gasoline requires energy too, does it not? The question is whether the energy required to make the steam is greater than the energy to be derived by converting the resulting hydrogen into energy either by combustion in an engine or by use in a fuel cell. -- -- --John to email, dial "usenet" and validate (was jclarke at eye bee em dot net) |

Until that question is answered, you're comparing apples to oranges. |
