Answer: Patent.

Explanation:

A patent is the property right reserved or granted to an inventor by a sovereign authority, this right confers on an inventor the sole right to the patented design, process, invention or discovery for a particular period of time. It is the right given to an inventor over his intention(s) that prohibits someone else from using the same idea or invention without proper permission from the inventor.

In the United States, most of the patent rights are for a valid period of 20 years, except in some exceptional cases where it could be extended.

Types of Patents.

•Plant Patents: used to protect someone who discovers a plant which can reproduce.

• Utility patents: Used to protect inventions such as machines, process or articles of manufacturing or production, etc

• Design patents: used to protect a design or logo for a product or good.

A steam reformer operating at 650C and 1 atm uses propane as fuel for hydrogen production. At the given operating conditions, th
dusya [7]

Answer:

Explanation:

a) for shifting reactions,

Kps =  ph2 pco2/pcoph20

=[h2] [co2]/[co] [h2o]

h2 + co2 + h2O + co + c3H8 = 1

it implies that

H2 + 0.09 + H2O + 0.08 + 0.05 = 1

solving the system of equation yields

H2 = 0.5308,

H2O = 0.2942

B)  according to Le chatelain's principle for a slightly exothermic reaction, an increase in temperature favors the reverse reaction producing less hydrogen. As a result, concentration of hydrogen in the reformation decreases with an increasing temperature.

c) to calculate the maximum hydrogen yield , both reaction must be complete

C3H8 + 3H2O ⇒ 3CO + 7H2( REFORMING)

CO + H2O ⇒ CO2 + H2 ( SHIFTING)

C3H8 + 6H2O ⇒ 3CO2 + 10 H2 ( OVER ALL)

SO,

Maximum hydrogen yield

= 10mol h2/3 molco2 + 10molh2

= 0.77

⇒ 77%
